libopenmpt 0.7.0 (2023-04-30)

  • [New] 667 files from Composer 667 are now supported.
  • [New] GTK and GT2 files from Gramouf Tracker are now supported.
  • [New] Can now read a variant of the DSMI AMF format called DMF, as found in various DOS games distributed by Webfoot (Tronic, H2O, PowBall, etc.).
  • [New] DSM files from Dynamic Studio are now supported.
  • [New] XMF files from the DOS game Imperium Galactica are now supported.
  • [New] Can now read the hacked MOD format (DMF) from the game "Apocalypse Abyss".
  • [New] libopenmpt: New APIs for getting the current tempo as a floating point value: openmpt::module::get_current_tempo2() (C++), and openmpt_module_get_current_tempo2() (C).
  • [New] C API: New stream callbacks for various platform extensions to the C stdio interface: openmpt_stream_get_file_posix_lfs64_callbacks() in libopenmpt/libopenmpt_stream_callbacks_file_posix_lfs64.h for explicit off64_t on Posix systems, openmpt_stream_get_file_posix_callbacks() in libopenmpt/libopenmpt_stream_callbacks_file_posix.h for off_t on Posix systems, openmpt_stream_get_file_msvcrt_callbacks() in libopenmpt/libopenmpt_stream_callbacks_file_msvcrt.h for 64bit file support on Windows systems with the Microsoft C runtime, and openmpt_stream_get_file_mingw_callbacks() in libopenmpt/libopenmpt_stream_callbacks_file_mingw.h for 64bit file support when targetting MinGW. The old openmpt_stream_get_file_callbacks() has been deprecated in favour of a stricly standard conforming openmpt_stream_get_file_callbacks2() in the same libopenmpt/libopenmpt_stream_callbacks_file.h header. libopenmpt/libopenmpt.h defines LIBOPENMPT_STREAM_CALLBACKS_FILE_POSIX_LFS64, LIBOPENMPT_STREAM_CALLBACKS_FILE_POSIX, LIBOPENMPT_STREAM_CALLBACKS_FILE_MSVCRT, and LIBOPENMPT_STREAM_CALLBACKS_FILE_MINGW respectively in order to allow for checking header availability.
  • [New] C API: New stream callbacks for memory buffers. openmpt_stream_get_buffer_callbacks() and openmpt_stream_buffer_init() are deprecated. Use openmpt_stream_get_buffer_callbacks2() and openmpt_stream_buffer_init2() instead. The new variants do not support loading only a file prefix and checking for overflow any more. This was only useful when using the old openmpt_could_open_probability2() style interface from the libopenmpt 0.2 API, which has been superseded by openmpt_probe_file_header(), openmpt_probe_file_header_without_filesize(), and openmpt_probe_file_header_from_stream() in libopenmpt 0.3.0.
  • [New] libopenmpt_ext: New interface interactive3 adding openmpt::ext::interactive3::set_current_tempo2() (C++) and openmpt_module_ext_interface_interactive3.set_current_tempo2() (C) which allow setting non-integer tempo values.
  • [New] New Makefile option CONFIG=mingw-w64 which consolidates all MinGW-w64 build configurations with the following options: MINGW_FLAVOUR=[|-posix|-win32], WINDOWS_ARCH=[x86|amd64], WINDOWS_FAMILY=[|desktop-app|app|phone-app|pc-app], and WINDOWS_VERSION=[win95|win98|winme|winnt4|win2000|winxp|winxp64|winvista|win7|win8|win8.1|win10|win11].
  • [New] New Makefile option CONFIG=mingw which consolidates all MinGW build configurations with the following options: MINGW_FLAVOUR=[|-posix|-win32], and WINDOWS_VERSION=[win95|win98|winme|winnt4|win2000|winxp].
  • [New] Building with MSYS2 is now fully supported for Makefile and Autotools build systems.
  • [New] Makefile CONFIG=djgpp now supports CPU= option to build optimized for a particular CPU. See build/make/config-djgpp.mk for all available options. FLAVOURED_DIR=1 places the CPU-specific optimized builds in separate folders below bin/.
  • [New] Building with a MinGW32 CRTDLL toolchain is now supported via Makefile option CONFIG=mingw32crt.
  • [New] Makefile now uses PKG_CONFIG as path to pkg-config.
  • [New] The C++ API is now also enabled for Emscripten builds by default.
  • [New] Support for GCC 7 has been restored.
  • [New] Support for Clang 6 has been restored.
  • [New] Support for Android NDK 18 has been restored.
  • [New] openmpt123: --banner [0|1|2] allows changing the openmpt123 banner style to hidden, shown, or verbose, respectively.
  • [New] openmpt123: --assume-terminal allows skipping the openmpt123 terminal check, and thus allows running the UI with non-terminal stdin, which can be useful for some very basic remote control functionality.
  • [Change] xmp-openmpt: The Amiga resampler emulation is now enabled by default.
  • [Change] in_openmpt: The Amiga resampler emulation is now enabled by default.
  • [Change] The official Windows builds (x86, amd64, arm, arm64) now require Windows 10 21H2 (or later). The official legacy Windows builds (x86-legacy, amd64-legacy) are unchanged and still require Windows 7 (or later).
  • [Change] "date" metadata will now exlude the UTC time zone signifier Z if the precise time zone is unknown.
  • [Change] ctl seek.sync_samples now defaults to 1.
  • [Change] Makefile CONFIG=generic is gone. Please use CONFIG=standard instead.
  • [Change] Makefile CONFIG=macosx and CONFIG=haiku have been removed. The OS is auto-detected.
  • [Change] Makefile options CONFIG=mingw64-win32, CONFIG=mingw64-win64, CONFIG=mingw64-winrt-x86, CONFIG=mingw64-winrt-amd64, and CONFIG=mingw-win9x have been replaced by CONFIG=mingw-w64, and CONFIG=mingw.
  • [Change] Autotools now default to C++20 and only fall back to C++17 when C++20 is not supported.
  • [Change] Makefile now defaults to C++20 and only falls back to C++17 when C++20 is not supported by the compiler.
  • [Change] Makefile now defaults to C17 and only falls back to C11 when C17 is not supported by the compiler.
  • [Change] Makefile CONFIG=djgpp option USE_ALLEGRO42 now defaults to 1 and implies building a liballegro42 locally. This requires executing build/download_externals.sh before building to download the liballegro42 sources.
  • [Change] in_openmpt: The Winamp input plugin in_openmpt is now deprecated for use with the latest Winamp or WACUP releases. Please use the native implementations available in Winamp >=5.9.0 or WACUP instead. This does not mean that in_openmpt/in_mod will not receive further development, it just means that the responsibility now lies with the player implementors themselves. We will still maintain the status quo of our in_openmpt input plugin for users of earlier Winamp version, or users on older systems, or users of compatible players.
  • [Change] The POSIX fd file callbacks implementation now handles EINTR and retries the read() call.
  • [Regression] Full support for Visual Studio 2017 has been removed. We still support targeting Windows XP with Visual Studio 2017.
  • [Regression] Support for mingw-std-threads has been removed. If you require a thread-safe libopenmpt, please build with POSIX threading model and/or complain to MinGW/GCC about not properly supporting C++11 features in 2023.
  • [Regression] Support for Emscripten versions older than 3.1.1 has been removed.
  • [Regression] C API: openmpt_stream_get_file_callbacks() used to provide 64bit file access on some platforms where long is 32bit. This never worked reliably for all platforms though. The behaviour is now changed to always stick to what standard C supports with fseek and ftell, where the offset type is long. openmpt_stream_get_file_callbacks() is deprecated now due to behavioral change. Please migrate to openmpt_stream_get_file_callbacks2().
  • [Regression] Using the system-provided liballegro42 is no longer supported. The option BUNDLED_ALLEGRO42=1 does not exist any more.
  • Reduced aliasing when downsampling with the Sinc + Low-Pass resampler.
  • The sample position is now rounded instead of truncated when resampling without interpolation.
  • Seeking with sample sync now supports portamento up / down commands as well as IMF/ PTM note slides. Tone portamento is now synchronized correctly when seeking in DBM, 669 and MED with fast slides (first tick of portamento was previously not executed).
  • The filter cutoff frequency is no longer rounded to integer frequency values.
  • MED: Tempos higher than 255 BPM can now be imported in pattern data.
  • MED: MMD1 files with more than 16 channels are now supported.
  • ULT: Import 8-bit volume commands with full precision.
  • IT: Initial "last note memory" of every channel is C-0, so a lone instrument number without note triggers that note.
  • S3M: Better approximation of old "stereo control" SAx command used in Purple Motion's PANIC.S3M.
  • S3M: In ScreamTracker 3.03 and later, OPL notes with tone portamento next to them are delayed until the next row and then the new pitch is used instantly.
  • MO3: Envelope sustain was not imported correctly if the source file was an XM.
  • MOD: Lone instrument number with retrigger effect swap sample immediately.
  • Recalling a sample's default volume using an instrument number (as opposed to regular volume commands) previously ramped the volume change smoothly over a whole tick. Now the user-configured ramp settings are used instead (as it would happen when using a volume command to achieve the same effect).
  • zlib: v1.2.12 (2022-03-27).
  • mpg123: v1.31.3 (2023-03-19).
  • ogg: v1.3.5 (2021-06-04).

  • minimp3: commit 50d2aaf360a53653b718fead8e258d654c3a7e41 (2021-11-27).
  • stb_vorbis: v1.22 commit 5a0bb8b1c1b1ca3f4e2485f4114c1c8ea021b781 (2021-07-12).
  • FLAC: v1.4.2 (2022-10-22).

  • [New] SymMOD files created with Symphonie / Symphonie Pro are now supported.
  • [New] FMT files created with Davey W Taylor's FM Tracker are now supported.
  • [New] DSYM files created with Digital Symphony are now supported.
  • [New] STX files (transitional format between Scream Tracker 2 and 3) are now supported.
  • [New] TakeTracker MODs with TDZ1 to TDZ3 magic bytes are now supported.
  • [New] openmpt123: openmpt123 will now expand file wildcards passed on the command line in Windows when built with MSVC.
  • [New] libopenmpt_ext: New interface interactive2 adding openmpt::ext::interactive2::note_off(), openmpt::ext::interactive2::note_fade(), openmpt::ext::interactive2::set_channel_panning(), openmpt::ext::interactive2::get_channel_panning(), openmpt::ext::interactive2::set_note_finetune(), and openmpt::ext::interactive2::get_note_finetune() (C++) and openmpt_module_ext_interface_interactive2.note_off(), openmpt_module_ext_interface_interactive2.note_fade(), openmpt_module_ext_interface_interactive2.set_channel_panning(), openmpt_module_ext_interface_interactive2.get_channel_panning(), openmpt_module_ext_interface_interactive2.set_note_finetune(), and openmpt_module_ext_interface_interactive2.get_note_finetune() (C).
  • [New] Makefile CONFIG=emscripten now supports EMSCRIPTEN_TARGET=audioworkletprocessor which builds an ES6 module in a single file with reduced dependencies suitable to be used in an AudioWorkletProcessor.
  • [New] Makefile CONFIG=emscripten now supports EMSCRIPTEN_PORTS=1 which uses dependencies (zlib, mp123, ogg, and vorbis) from Emscripten Ports instead of using miniz, minimp3, and stb_vorbis locally or building zlib, mp123, ogg, and vorbis locally.
  • [New] Makefile CONFIG=emscripten and CONFIG=djgpp can now build zlib, mpg123, and vorbis locally instead of only supporting miniz, minimp3, and stb_vorbis via ALLOW_LGPL=1.
  • [Change] Makefile CONFIG=emscripten now supports EMSCRIPTEN_TARGET=all which provides WebAssembly as well as fallback to JavaScript in a single build.
  • [Change] openmpt123: DOS builds now use the Mercury fork of liballegro 4.2 for improved hardware compatibility.
  • [Change] libopenmpt no longer generates internal interpolation tables on library load time, but instead only on first module load time.
  • [Regression] Makefile CONFIG=emscripten does not support EMSCRIPTEN_TARGET=asmjs or EMSCRIPTEN_TARGET=asmjs128m any more because support has been removed from current Emscripten versions.
  • [Regression] Support for GCC 7 has been removed.
  • [Regression] Support for Clang 5, 6 has been removed.
  • [Regression] Support for Emscripten versions older than 1.39.7 has been removed.
  • [Regression] Building with Android NDK older than NDK r19c is not supported any more.
  • libopenmpt can now detect infinite pattern loops and treats them as the song end. This means that setting a repeat count other than -1 now always guarantees that playback will eventually end. The song loop counter is decremented each time it ends up at the start of the infinite loop, so the song does not restart from the beginning even if the repeat count is not 0.
  • openmpt::module::set_position_seconds() accuracy has been improved for modules with pattern loops.
  • Samples played at the wrong volume when rendering modules in mono.
  • IT: Portamentos in files with Linear Slides disabled are now more accurate.
  • IT: Pitch/Pan Separation was affected by note-off commands, and wasn't reset by panning commands like in Impulse Tracker.
  • IT: Even after libopenmpt 0.5.14 the filter reset logic was still not 100% identical to Impulse Tracker: A note triggered on tick 0 of a row with a Pattern Delay effect still caused the filter to be reset on repetitions of that row even though the note wasn't retriggered.
  • IT: Added read-only support for BeRoTracker commands 1 and 2 (equivalent to XM commands K and L).
  • XM: BeRoTracker saves smooth MIDI macros in a different way from OpenMPT. This command is now imported correctly.
  • XM: Emulate FT2 Tone Portamento quirk that inverts portamento direction after the target was reached (if target note was higher than previous note).
  • S3M files saved with Impulse Tracker and latest Schism Tracker now also compute sample playback speed in Hertz.
  • Depending on whether an S3M file was last saved in Scream Tracker with the Sound Blaster or Gravis Ultrasound drivers loaded, different compatibility flags are now applied. For files saved with the GUS, the sample volume factor is now also ignored (fixes volume levels in S3Ms made on the GUS, in particular if they use both samples and OPL instruments).
  • S3M: Enforce the lower frequency bound.
  • MOD: Loosened VBlank timing heuristics so that the original copy of Guitar Slinger from Dizzy Tunes II plays correctly.
  • FAR: Correct portamento depth is now used.
  • DMF / IMF: Improved accuracy of finetune commands.
  • MDL: Implemented finetune command.
  • OKT: Various accuracy improvements such as: Sharing volume between mixed channels, volume commands on mixed channels are permanent (not reset with new notes), mixed channels do not support default sample volume, 7-bit samples are actually supposed to be played as-is (not amplified to full 8-bit range), reject speed command parameters >= 20.
  • zlib: v1.2.11 (2017-01-15).
  • mpg123: v1.29.3 (2021-12-11).
  • ogg: v1.3.5 (2021-06-04).
  • vorbis: v1.3.7 (2020-07-04).
  • miniz: v2.2.0 (2021-06-27).
  • minimp3: commit 50d2aaf360a53653b718fead8e258d654c3a7e41 (2021-11-27).
  • stb_vorbis: v1.22 commit 5a0bb8b1c1b1ca3f4e2485f4114c1c8ea021b781 (2021-07-12).
  • FLAC: v1.3.3 (2019-08-04).
  • PortAudio: v19.7.0 (2021-04-06).

libopenmpt 0.5.0 (2020-05-24)

  • [New] OggMod compressed FastTracker 2 XM (OXM) modules are now supported.
  • [New] The emulated Amiga type when Amiga resampler emulation is enabled can now be selected via ctl render.resampler.emulate_amiga_type. Possible values are: "auto", "a500", "a1200", and an experimental option "unfiltered".
  • [New] libopenmpt: New API openmpt::module::get_current_estimated_bpm() (C++), and openmpt_module_get_current_estimated_bpm() (C) which provides accurate beats per minute information for module formats with time signature and an educated guess based on speed and tempo for others.
  • [New] libopenmpt: New type-aware ctl APIs that do not require memory allocations and are thus realtime-safe: openmpt::module::ctl_get_boolean(), openmpt::module::ctl_get_integer(), openmpt::module::ctl_get_floatingpoint(), openmpt::module::ctl_get_text(), openmpt::module::ctl_set_boolean(), openmpt::module::ctl_set_integer(), openmpt::module::ctl_set_floatingpoint() (C++), and openmpt_module_ctl_get_boolean(), openmpt_module_ctl_get_integer(), openmpt_module_ctl_get_floatingpoint(), openmpt_module_ctl_get_text(), openmpt_module_ctl_set_boolean(), openmpt_module_ctl_set_integer(), openmpt_module_ctl_set_floatingpoint() (C).
  • [New] libopenmpt C++ New API openmpt::is_extension_supported2() which takes a std::string_view parameter instead of std::string.
  • [New] libopenmpt C++: New API openmpt::module::module(std::vector<std::byte> data), openmpt::module::module(const std::byte * data, std::size_t size), openmpt::module::module(const std::byte * beg, const std::byte * end).
  • [New] libopenmpt C++: New API openmpt::probe_file_header(flags, const std::byte * data, std::size_t size, filesize), openmpt::probe_file_header(flags, const std::byte * data, std::size_t size).
  • [New] libopenmpt_ext C++: New API openmpt::module_ext::module_ext(std::vector<std::byte> data), openmpt::module_ext::module_ext(const std::byte * data, std::size_t size), openmpt::module_ext::module_ext(std::vector<std::uint8_t> data), openmpt::module_ext::module_ext(const std::uint8_t * data, std::size_t size).
  • [Change] std::istream based file I/O has been speed up.
  • [Change] Dependency on iconv on Linux has been removed.
  • [Regression] libmodplug: The libmodplug emulation layer has been removed from the libopenmpt tree. Please use the separate libopenmpt-modplug package instead.
  • [Regression] foo_openmpt: foo_openmpt is discontinued. Please use Kode54's fork foo_openmpt54: https://www.foobar2000.org/components/view/foo_openmpt54.
  • [Regression] Support for building with C++11 or C++14 has been removed. C++17 is now required to build libopenmpt.
  • [Regression] Support for client code using C++11 or C++ 14 has been removed. C++17 is now required to build libopenmpt client applications.
  • [Regression] Support for Visual Studio 2015 has been removed.
  • [Regression] Support for GCC 4.8, 4.9, 5, 6 has been removed.
  • [Regression] Support for Clang 3.6, 3.7, 3.8, 3.9, 4 has been removed.
  • [Regression] Support for Emscripten versions older than 1.39.1 has been removed.
  • [Regression] Building with Android NDK older than NDK r18b is not supported any more.
  • [Regression] openmpt123: Support for SDL1 (but not SDL2) output has been removed.
  • [Regression] openmpt123: Support for SDL2 older than 2.0.4 has been removed.
  • [Regression] Windows XP and Windows Vista are no longer supported.
  • [Regression] It is no longer possible to optionally use iconv for character set conversions.
  • [Bug] openmpt123: openmpt123 now honors the current locale and outputs text appropriately.
  • [Bug] openmpt123: Piping text output to other than console window targets on Windows has been fixed.
  • Greatly improved MED import. Synthesized instruments are still not supported but support was added for: Multisampled instruments, delta samples, more pattern commands, Hold and Decay, multiple songs and many other small changes.
  • Improved OPL channel allocation when more than 18 notes are active, so that channels that have completely faded out are prioritized over channels that have already been released but have not faded out yet.
  • Interactively triggering an OPL instrument could cause the first pattern channel to no longer be played back correctly.
  • Fix some inaccuracies in OPL emulator.
  • Fix overflow of OPL amplification happening at a synth volume level of 510.
  • End-of-sample pop reduction of surround channels was applied to front channels instead, causing a pop on the front channels instead of removing it on the back channels.
  • IT: Disable retrigger with short notes quirk for modules saved with Chibi Tracker, as it does not implement that quirk.
  • IT: Instrument and sample panning should not override channel panning for following notes.
  • IT: SBx is now prioritized over Bxx commands that are to the left of it.
  • IT: Duplicate Check Type "Sample" should only be applied if the instruments match, too.
  • IT: Duplicate Check Type "Note" should compare pattern notes, but it was comparing the new pattern note against the old translated note.
  • IT: Various fixes for envelope resetting.
  • IT / S3M: When combining SBx and EEx effects, don't skip the first row of the loop like in FastTracker 2.
  • S3M: Empty pattern commands now affect effect memory as well.
  • S3M: Offset beyond loop end wraps around to loop start like in Scream Tracker 3 + GUS (previously it just keep playing from the loop start, which is neither what GUS nor Sound Blaster drivers do).
  • S3M: Notes cannot be retriggered after they have been cut.
  • S3M: Fix portamento after note cut (fixes antediluvian_song.s3m).
  • S3M / MOD: Previous note offset is no longer used for retriggered notes if there was no instrument number next to the Qxy effect.
  • MOD: Sample swapping now also works if the sample that is being swapped from does not loop. Swapping to a non-looped sample now stops playback once the swapped-from sample reaches its (loop) end.
  • MOD: Fix early song ending due to ProTracker pattern jump quirk (EEx + Dxx on same row) if infinite looping is disabled. Fixes Haunted Tracks.mod by Triace.
  • MOD: Previous note offset is no longer used for retriggered notes if there was no instrument number next to the E9x effect.
  • MOD: Vibrato type "ramp down" was upside down.
  • XM: If a file contains patterns longer than 1024 rows, they are now clamped to 1024 rows instead of 64 rows.
  • XM: Do not reset note-off status on portamento if there is no instrument number.
  • mpg123: v1.26rc3.
  • ogg: v1.3.4.
  • vorbis: v1.3.6.
  • zlib: v1.2.11.
  • minimp3: commit 55da78cbeea5fb6757f8df672567714e1e8ca3e9 (2020-03-04).
  • stb_vorbis: v1.19 commit 37b9b20fdec06c75a0493e0bb59e2d0f288bfb51 (2020-02-05).
  • miniz: v2.1.0.
  • FLAC: v1.3.3.
  • PortAudio: commit 799a6834a58592eadc5712cba73b35956dc51579 (2020-03-26).

libopenmpt 0.4.0 (2018-12-23)

  • [New] libopenmpt now includes emulation of the OPL chip and thus plays OPL instruments in S3M, C67 and MPTM files. OPL chip emulation volume can be changed with the new ctl render.opl.volume_factor.
  • [New] libopenmpt now supports CDFM / Composer 670 module files.
  • [New] Autotools configure and plain Makefile now honor the variable CXXSTDLIB_PCLIBSPRIVATE which serves the sole purpose of listing the standard library (or libraries) required for static linking. The contents of this variable will be put in libopenmpt.pc Libs.private and used for nothing else. See Statically linking to libopenmpt .
  • [New] foo_openmpt: foo_openmpt now also works on Windows XP.
  • [New] libopenmpt Emscripten builds now ship with MP3 support by default, based on minimp3 by Lion (github.com/lieff).
  • [New] libopenmpt: New ctl play.at_end can be used to change what happens when the song end is reached:
    • "fadeout": Fades the module out for a short while. Subsequent reads after the fadeout will return 0 rendered frames. This is the default and identical to the behaviour in previous libopenmpt versions.
    • "continue": Returns 0 rendered frames when the song end is reached. Subsequent reads will continue playing from the song start or loop start. This can be used for custom loop logic, such as loop auto-detection and longer fadeouts.
    • "stop": Returns 0 rendered frames when the song end is reached. Subsequent reads will return 0 rendered frames.
  • [New] Add new metadata fields "originaltype" and "originaltype_long" which allow more clearly reflecting what is going on with converted formats like MO3 and GDM.
  • [New] Makefile CONFIG=emscripten now can generate WebAssembly via the additional option EMSCRIPTEN_TARGET=wasm.
  • [New] Compiling for DOS is now experimentally supported via DJGPP GCC 7.2 or later.
  • [Change] minimp3: Instead of the LGPL-2.1-licensed minimp3 by KeyJ, libopenmpt now uses the CC0-1.0-licensed minimp3 by Lion (github.com/lieff) as a fallback if libmpg123 is unavailable. The USE_MINIMP3 Makefile option is gone and minimp3 will be used automatically in the Makefile build system if libmpg123 is not available.
  • [Change] openmpt123: openmpt123 now rejects --output-type in --ui and --batch modes and also rejects --output in --render mode. These combinations of options really made no sense and were rather confusing.
  • [Change] Android NDK build system now uses libc++ (c++_shared) instead of GNU libstdc++ (gnustl_shared), as recommended by Android NDK r16b.
  • [Change] xmp-openmpt: openmpt-mpg123.dll is no longer optional and must be placed into the same directory as xmp-openmpt.dll.
  • [Change] in_openmpt: openmpt-mpg123.dll is no longer optional and must be placed either into the directory of the player itself or into the same directory as in_openmpt.dll. This is dependent on how the player loads its plugins. For WinAMP 5, openmpt-mpg123.dll needs to be in the directory which contains winamp.exe. in_openmpt.dll needs to be in the Plugins directory.
  • [Change] foo_openmpt: foo_openmpt is now packaged as a fb2k-component package for easier installation.
  • [Change] When building libopenmpt with MinGW-w64, it is now recommended to use the posix thread model (as opposed to the win32 threading model), because the former does support std::mutex while the latter does not. When building with win32 threading model with the Autotools build system, it is recommended to provide the mingw-std-threads package. Building libopenmpt with MinGW-w64 without any std::thread/std::mutex support is deprecated and support for such configurations will be removed in libopenmpt 0.5.
  • [Change] Makefile CONFIG=emscripten now has 4 EMSCRIPTEN_TARGET= settings: wasm generates WebAssembly, asmjs128m generates asm.js with a fixed size 128MB heap, asmjs generates asm.js with a fixed default size heap (as of Emscripten 1.38.11, this amounts to 16MB), js generates JavaScript with dynamic heap growth and with compatibility for older VMs.
  • [Change] libmodplug: Update public headers to libmodplug 0.8.8.5. This adds support for kind-of automatic MODPLUG_EXPORT decoration on Windows.
  • [Regression] Support for Clang 3.4, 3.5 has been removed.
  • [Regression] Building with Android NDK older than NDK r16b is not supported any more.
  • [Regression] Support for Emscripten versions older than 1.38.5 has been removed.
  • [Regression] Support for libmpg123 older than 1.14.0 has been removed.
  • [Regression] Using MediaFoundation to decode MP3 samples is no longer supported. Use libmpg123 or minimp3 instead.
  • [Regression] libmodplug: Support for emulating libmodplug 0.8.7 API/ABI has been removed.
  • [Bug] xmp-openmpt: Sample rate and number of output channels were not applied correctly when using per-file settings.
  • [Bug] Internal mixer state was not initialized properly when initially rendering in 44100kHz stereo format.
  • [Bug] openmpt123: Prevent libsdl2 and libsdl from being enabled at the same time because they conflict with each other.
  • [Bug] libmodplug: Setting SNDMIX_NORESAMPLING in the C++ API always resulted in linear interpolation instead of nearest neighbour
  • IT: In Compatible Gxx mode, allow sample changes next to a tone portamento effect if a previous sample has already stopped playing.
  • IT: Fix broken volume envelopes with negative values as found in breakdwn.it by Elysis.
  • MOD: Slides and delayed notes are executed on every repetition of a row with row delay (fixes "ode to protracker").
  • XM: If the sustain point of the panning envelope is reached before key-off, it is never released.
  • XM: Do not default recall volume / panning for delayed instrument-less notes
  • XM :E60 loop bug was not considered in song length calucation.
  • S3M: Notes without instrument number use previous note's sample offset.
  • Tighten M15 and MOD file rejection heuristics.
  • J2B: Ignore frequency limits from file header. Fixes Medivo.j2b, broken since libopenmpt-0.2.6401-beta17.
  • STM: More accurate tempo calculation.
  • STM: Better support for early format revisions (no such files have been found in the wild, though).
  • STM: Last character of sample name was missing.
  • SFX: Work around bad conversions of the "Operation Stealth" soundtrack by turning pattern breaks into note stops.
  • IMF: Filter cutoff was upside down and the cutoff range was too small.
  • ParamEq plugin center frequency was not limited correctly.
  • Keep track of active SFx macro during seeking.
  • The "note cut" duplicate note action did not volume-ramp the previously playing sample.
  • A song starting with non-existing patterns could not be played.
  • DSM: Support restart position and 16-bit samples.
  • DTM: Import global volume.
  • MOD: Support notes in octave 2, like in FastTracker 2 (fixes DOPE.MOD).
  • Do not apply Amiga playback heuristics to MOD files that have clearly been written with a PC tracker.
  • MPTM: More logical release node behaviour.
  • Subsong search is now less thorough. It could previously find many subsongs that are technically correct (unplayed rows at the beginning of patterns that have been jumped over due to pattern breaks), but so far no real-world module that would require such a thorough subsong detection was found. The old mechanism caused way more false positives than intended with real-world modules, though.
  • Restrict the unpacked size of compressed DMF, IT, MDL and MO3 samples to avoid huge allocations with malformed small files.

libopenmpt 0.3 (2017-09-27)

  • [New] New error handling functionality in the C API, which in particular allows distinguishing potentially transient out-of-memory errors from parse errors during module loading.
  • [New] New API openmpt::module::get_selected_subsong() (C++) and openmpt_module_get_selected_subsong() (C).
  • [New] Faster file header probing API openmpt::probe_file_header() and openmpt::probe_file_header_get_recommended_size (C++), and openmpt_probe_file_header(), openmpt_probe_file_header_without_filesize(), openmpt_probe_file_header_from_stream() and openmpt_probe_file_header_get_recommended_size() (C).
  • [New] New API openmpt::could_open_probability() (C++) and openmpt_could_open_probability() (C). This fixes a spelling error in the old 0.2 API.
  • [New] openmpt123: openmpt123 can now open M3U, M3U8, M3UEXT, M3U8EXT and PLSv2 playlists via the --playlist option.
  • [New] openmpt123: openmpt123 now supports very fast file header probing via the --probe option.
  • [New] Libopenmpt now supports building for Windows 10 Universal (Windows Store 8.2) APIs with MSVC, and also for the older Windows Runtime APIs with MinGW-w64.
  • [New] New API header libopenmpt_ext.h which implements the libopenmpt extension APIs also for the C interface.
  • [New] The Reverb effect (S99 in S3M/IT/MPTM, and X99 in XM) is now implemented in libopenmpt.
  • [New] For Amiga modules, a new resampler based on the Amiga's sound characteristics has been added. It can be activated by passing the render.resampler.emulate_amiga ctl with a value of 1. Non-Amiga modules are not affected by this, and setting the ctl overrides the resampler choice specified by OPENMPT_MODULE_RENDER_INTERPOLATIONFILTER_LENGTH or openmpt::module::RENDER_INTERPOLATIONFILTER_LENGTH. Support for the MOD command E0x (Set LED Filter) is also available when the Amiga resampler is enabled.
  • [Change] libopenmpt versioning changed and follows the more conventional major.minor.patch as well as the recommendations of the SemVer scheme now. In addition to the SemVer requirements, pre-1.0.0 versions will also honor API and ABI stability in libopenmpt (i.e. libopenmpt ignores SemVer Clause 4).
  • [Change] The output directories of the MSVC build system were changed to bin/vs2015-shared/x86-64-win7/ (and similar) layout which allows building in the same tree with different compiler versions without overwriting other outputs.
  • [Change] The emscripten build now exports libopenmpt as 'libopenmpt' instead of the default 'Module'.
  • [Change] Android: The build system changed. The various Android.mk files have been merged into a single one which can be controlled using command line options.
  • [Change] The Makefile build system now passes std=c++11 to the compiler by default. Older compilers may still work if you pass STDCXX=c++0x to the make invocation.
  • [Change] The Makefile option ANCIENT=1 is gone.
  • [Change] The optional dependencies on libltdl or libdl are gone. They are no longer needed for any functionality.
  • [Regression] Compiling client code using the C++ API now requires a compiler running in C++11 mode.
  • [Regression] Support for GCC 4.1, 4.2, 4.3, 4.4, 4.5, 4.6, 4.7 has been removed.
  • [Regression] Support for Clang 3.0, 3.1, 3.2, 3.3 has been removed.
  • [Regression] Support for Emscripten versions older than 1.31.0 has been removed.
  • [Regression] Support for Android NDK versions older than 11 has been removed.
  • [Regression] Visual Studio 2008, 2010, 2012, 2013 support has been removed.
  • [Regression] Dynamic run-time loading of libmpg123 is no longer supported. Libmpg123 must be linked at link-time now.
  • [Regression] xmp-openmpt: xmp-openmpt now requires XMPlay 3.8 or later and compiling xmp-openmpt requires an appropriate XMPlay SDK with XMPIN_FACE >= 4.
  • [Regression] Support for libmpg123 older than 1.13.0 has been removed.
  • [Regression] Un4seen unmo3 support has been removed.
  • [Bug] C++ API: openmpt::exception did not define copy and move constructors or copy and move assignment operators in libopenmpt 0.2. The compiler-generated ones were not adequate though. libopenmpt 0.3 adds the appropriate special member functions. This adds the respective symbol names to the exported ABI, which, depending on the compiler, might or might not have been there in libopenmpt 0.2. The possibly resulting possible ODR violation only affects cases that did crash in the libopenmpt 0.2 API anyway due to memory double-free, and does not cause any further problems in practice for all known platforms and compilers.
  • [Bug] The C API could crash instead of failing gracefully in out-of-memory situations.
  • [Bug] The test suite could fail on MacOSX or FreeBSD in non-fatal ways when no locale was active.
  • [Bug] libopenmpt_stream_callbacks_fd.h and libopenmpt_stream_callbacks_file.h were missing in Windows development packages.
  • [Bug] libopenmpt on Windows did not properly guard against current working directory DLL injection attacks.
  • [Bug] localtime() was used to determine the version of Schism Tracker used to save IT and S3M files. This function is not guaranteed to be thread-safe by the standard and is now no longer used.
  • [Bug] Possible crashes with malformed IT, ITP, AMS, MDL, MED, MPTM, PSM and Startrekker files.
  • [Bug] Possible hangs with malformed DBM, MPTM and PSM files.
  • [Bug] Possible hangs with malformed files containing cyclic plugin routings.
  • [Bug] Excessive loading times with malformed ITP / truncated AMS files.
  • [Bug] Plugins did not work correctly when changing the sample rate between two render calls.
  • [Bug] Possible NULL-pointer dereference read during obscure out-of-memory situations while handling exceptions in the C API.
  • [Bug] libmodplug: libmodplug.pc was wrong.
  • [Bug] Cross-compiling libopenmpt with autotools for Windows now properly sets -municode and -mconsole as well as all required Windows system libraries.
  • [Bug] foo_openmpt: Interpolation filter and volume ramping settings were confused in previous versions. This version resets both to the defaults.
  • [Bug] libmodplug: The CSoundFile::Read function in the emulated libmodplug C++ API returned the wrong value, causing qmmp (and possibly other software) to crash.
  • Support for SoundTracker Pro II (STP) and Digital Tracker (DTM) modules.
  • Increased accuracy of the sample position and sample rate to drift less when playing very long samples.
  • Various playback improvements for IT and XM files.
  • Channel frequency could wrap around after some excessive portamento / down in some formats since libopenmpt 0.2-beta17.
  • Playback improvements for S3M files made with Impulse Tracker and Schism Tracker.
  • ParamEq plugin emulation didn't do anything at full gain (+15dB).
  • All standard DMO effects are now also emulated on non-Windows and non-MSVC systems.
  • Added libopenmpt_stream_callbacks_buffer.h which adds openmpt_stream_callbacks support for in-memory buffers, possibly even only using a truncated prefix view into a bigger file which is useful for probing.
  • Avoid enabling some ProTracker-specific quirks for MOD files most likely created with ScreamTracker 3.
  • Tremolo effect only had half the intended strength in MOD files.
  • Pattern loops ending on the last row a pattern were not executed correctly in S3M files.
  • Work-around for reading MIDI macros and plugin settings in some malformed IT files written by old UNMO3 versions.
  • Improve tracker detection in IT format.
  • Playback fixes for 8-channel MED files
  • Do not set note volume to 0 on out-of-range offset in XM files.
  • Better import of some slide commands in SFX files.
  • Sample 15 in "Crew Generation" by Necros requires short loops at the beginning of the sample to not be ignored. Since we need to ignore them in some (non-ProTracker) modules, we heuristically disable the old loop sanitization behaviour based on the module channel count.
  • Both normal and percentage offset in PLM files were handled as percentage offset.
  • MT2 files with instruments that had both sample and plugin assignments were not read correctly.
  • Some valid FAR files were rejected erroneously.
  • Support for VBlank timing flag and comment field in PT36 files.
  • Improved accuracy of vibrato command in DIGI / DBM files.
  • STM: Add support for "WUZAMOD!" magic bytes and allow some slightly malformed STM files to load which were previously rejected.
  • Detect whether "hidden" patterns in the order list of SoundTracker modules should be taken into account or not.
  • Tighten heuristics for rejecting invalid 669, M15, MOD and ICE files and loosen them in other places to allow some valid MOD files to load.
  • Improvements to seeking: Channel panning was not always updated from instruments / samples when seeking, and out-of-range global volume was not applied correctly in some formats.
  • seek.sync_samples=1 did not apply PTM reverse offset effect and the volume slide part of combined volume slide + vibrato commands.
  • If the order list was longer than 256 items and there was a pattern break effect without a position jump on the last pattern of the sequence, it did not jump to the correct restart order.
  • Makefile has now explicit support for FreeBSD with no special option or configuration required.
  • openmpt123: Improved section layout in man page.
  • libmodplug: Added all missing C++ API symbols that are accessible via the public libmodplug header file.
  • Autotools build system now has options --disable-openmpt123, --disable-tests and --disable-examples which may be desireable when cross-compiling.
  • Windows binary packages now ship with libmpg123 included.

libopenmpt 0.2-beta20 (2016-08-07)

  • [Bug] PSM loader was broken on big-endian platforms since forever.
  • [Bug] load.skip_samples ctl did not work for PSM16 modules.
  • There is a new subsong ctl, which can return the currently selected subsong.
  • More accurate ProTracker arpeggio wrap-around emulation.
  • More accurate sample tuning in PSM16 files.
  • Samples in DSM files were sometimes detuned and some pattern commands were not imported correctly.
  • More accurate import of MDL 7-bit panning command.
  • Only import pattern commands supported by the UltraTracker version that was used to save ULT files. Add support for command 5-C (end loop).
  • DMF sample loop lengths were off by one.
  • Unis 669 pan slide effect was too deep.
  • Several valid (but slightly corrupted possibly due to disk failures or data transfer errors) SoundTracker files were no longer loading since libopenmpt 0.2-beta18.

libopenmpt 0.2-beta19 (2016-07-23)

  • [Change] libopenmpt now uses C++14 [[deprecated]] attribute instead of compiler-specific solutions when appropriate.
  • [Change] libopenmpt C++ header now uses C++11 noexcept instead of C++98 throw() exception specification when supported. throw() is deprecated since C++11. This does not change API or ABI as they are equivalent. Use LIBOPENMPT_ASSUME_CPLUSPLUS_NOEXCEPT to override the default.
  • [Change] The preprocessor macro LIBOPENMPT_ANCIENT_COMPILER_STDINT is gone. Please use LIBOPENMPT_ASSUME_CPLUSPLUS_CSTDINT instead. Additionally, the typedefs moved from illegal namespace ::std into somewhat less dangerous namespace ::openmpt::std. You can test #ifdef LIBOPENMPT_QUIRK_NO_CSTDINT client-side to check whether libopenmpt.hpp used the non-standard types. (Note: Of all supported compilers, this change only affects the 3 compilers with only limited support: MSVC 2008, GCC 4.1, GCC 4.2.)
  • [Bug] xmp-openmpt: Crash when viewing sample texts.
  • The public libopenmpt C++ header has auto-detection logic for the used C++ standard now. In case your client code compiler misreports the standard version or you want to override it for other reasons, #define LIBOPENMPT_ASSUME_CPLUSPLUS to the value of the standard version you desire to be used. There is also a macro for each individual aspect, like LIBOPENMPT_ASSUME_CPLUSPLUS_CSTDINT, LIBOPENMPT_ASSUME_CPLUSPLUS_DEPRECATED, LIBOPENMPT_ASSUME_CPLUSPLUS_NOEXCEPT which take precedence over the general macro.
  • Portamento with sample swap behaviour was wrong for ProTracker MODs.
  • Rewritten loader and various playback fixes for MDL files.
  • libopenmpt 0.2-beta18 broke import of many pattern commands in DBM, DMF and ULT files.
  • ADPCM samples in MOD files were broken since libopenmpt 0.2-beta17.

libopenmpt 0.2-beta18 (2016-07-11)

  • [Change] openmpt123: Add PulseAudio output support. Autotools and Makefile build systems now depend on libpulse and libpulse-simple by default. Disable with --without-pulseaudio or NO_PULSEAUDIO=1 respectively. When enabled, PulseAudio will be the default output driver,
  • [Change] xmp-openmpt: Settings are now stored in xmplay.ini like with every other plugin.
  • [Regression] openmpt123: Support for FLAC < 1.3.0 has been removed. FLAC before 1.3.0 is broken beyond repair as it provides assert.h in the include path.
  • [Bug] Generated pkg-config file libopenmpt.pc by both Makefile and Autotools build systems was totally broken.
  • [Bug] libopenmpt no longer uses the non-thread-safe global std::rand() function.
  • [Bug] Sample loops in GDM modules did not work when using Emscripten.
  • [Bug] XM and MO3 loaders could crash due to unaligned memory accesses.
  • [Bug] Fixed incorrect handling of custom MPTM tunings on big endian platforms.
  • [Bug] Fixed various problems found with clang 3.8 static analyzer, address sanitizer and undefined behaviour sanitizer.
  • [Bug] File header probing functionality was broken for most formats.
  • [Bug] With non-seekable streams, the entire file was almost always cached even if it was not of any supported module type.
  • Seeking in allsubsongs-mode now works correctly.
  • openmpt123: Added subsong support.
  • Various playback fixes for 669, IT, MT2 and MTM files.
  • Some MOD files with more than 128 patterns (e.g. NIETNU.MOD) were not loaded correctly.
  • A new example libopenmpt_example_c_probe has been added which demonstrates the usage and flexibility of openmpt_could_open_propability() in the C API under various constraints.

libopenmpt 0.2-beta17 (2016-05-21)

  • [Change] The Makefile and Autotools build systems now require to explicitly specify NO_LTDL=1 or --without-ltdl respectively if no support for dynamic loading of third party libraries via libtool libltdl is desired.
  • [Change] In the Makefile build system option USE_MO3 and the Autotools build system option --enable-mo3 are gone. Dynamic loading of un4seen unmo3 is now always enabled when dynamic loading is possible and built-in MO3 support is not possible because either a MP3 or a Vorbis decoder is missing.
  • [Change] The MSVC build system changed. The libopenmptDLL project is gone. Use the new ReleaseShared configuration of the libopenmpt project instead. libopenmpt now links against zlib by default. A separate project with smaller footprint linking against miniz is still available as libopenmpt-small.
  • [Change] The constants used to query library information from openmpt_get_string() and openmpt::string::get() (i.e. OPENMPT_STRING_FOO and openmpt::string::FOO) have been deprecated because having syntactic constants for theses keys makes extending the API in a backwards and forwards compatible way harder than it should be. Please just use the string literals directly.
  • [Change] Deprecated API identifiers will now cause deprecation warnings with MSVC, GCC and clang. #define LIBOPENMPT_NO_DEPRECATE to disable the warnings.
  • [Change] openmpt123: --[no-]shuffle option has been renamed to --[no-]randomize. A new --[no-]shuffle option has been added which shuffles randomly through the playlist as opposed to randomizing the playlist upfront.
  • [Change] Support for Un4seen unmo3 has generally been deprecated in favour of the new internal mo3 decoder. Un4seen unmo3 support will be removed on 2018-01-01.
  • [Bug] Memory consumption during loading has been reduced by about 1/3 in case a seekable input stream is provided (either via C API callback open functions or via C++ API iostream constructors).
  • [Bug] Some samples in AMS modules were detuned when using Emscripten.
  • [Bug] Possible crash with excessive portamento down in some formats.
  • [Bug] Possible crashes with malformed AMF, AMS, DBM, IT, MDL, MED, MPTM, MT2, PSM and MMCMP-, XPK- and PP20-compressed files.
  • [Bug] openmpt::module::format_pattern_row_channel with width == 0 was returning an empty string instead of an string with unconstrained length.
  • Support for ProTracker 3.6 IFF-style modules and SoundFX / MultiMedia Sound (SFX / MMS) modules.
  • libopenmpt now has support for DMO plugins on Windows when built with MSVC. Additionally, the DMO Compression, Distortion, Echo, Gargle, ParamEQ and WavesReverb DSPs are emulated on on all other platforms.
  • libopenmpt now supports the DigiBooster Echo DSP.
  • To avoid any of the aforementioned plugins to be used, the load.skip_plugins ctl can be passed when loading a module.
  • libopenmpt got native MO3 support with MP3 decoding either via libmpg123 or MediaFoundation (on Windows 7 and up) and Vorbis decoding via libogg, libvorbis, libvorbisfile or stb_vorbis.
  • libopenmpt MSVC builds with Visual Studio 2010 or later on Windows 7 or later now use an internal MO3 decoder with libogg, libvorbis, libvorbisfile, and libmpg123 or minimp3 or MediaFoundation suppport by default. Visual Studio 2008 builds still use unmo3.dll by default but also support the built-in decoder in which case libmpg123 is required.
  • libopenmpt with Makefile or Autotools build system can now also use glibc/libdl instead of libtool/libltdl for dynamic loading of third-party libraries. Options NO_DL=1 and --without-dl have been added respectively.
  • The Makefile build system got 4 new options NO_MPG123, NO_OGG, NO_VORBIS, NO_VORBISFILE. The default is to use the new dependencies automatically.
  • The Autotools build system got 4 new options –without-mpg123, –without-ogg, –without-vorbis, –without-vorbisfile. The default is to use the new dependencies automatically.
  • Makefile and Android builds got support for using minimp3 instead of libmpg123. For Android, use Android-minimp3-stbvorbis.mk, for Makefile use USE_MINIMP3=1. You have to download minimp3 yourself and put its contents into include/minimp3/.
  • "source_url", "source_date" and "build_compiler" keys have been added to openmpt_string_get() and openmpt::string::get().
  • openmpt123: Add new --[no-]restart] option which restarts the playlist when finished.
  • Improved Ultimate SoundTracker version detection heuristics.
  • Playing a sample at a sample rate close to the mix rate could lead to small clicks when using vibrato.
  • More fine-grained internal legacy module compatibility settings to correctly play back modules made with older versions of OpenMPT and a few other trackers.
  • The tail of compressed MDL samples was slightly off.
  • Some probably hex-edited XM files (e.g. cybernostra weekend.xm) were not loaded correctly.
  • Countless other playback fixes for MOD, XM, S3M, IT and MT2 files.

libopenmpt 0.2-beta16 (2015-11-22)

  • [Change] The Autotools build system does strict checking of all dependencies now. Instead of best effort auto-magic detection of all potentially optional dependencies, the default set of dependencies is now enforced unless each individual dependency gets explicitely disabled via --without-foo or --disable-foo ./configure switches. Run ./configure --help for the full list of options.
  • [Bug] Some MOD files were erroneously detected as 669 files.
  • [Bug] Some malformed AMF files could result in very long loading times.
  • [Bug] Fixed crashes in IMF and MT2 loaders.
  • [Bug] MTM files generated by UNMO3 were not loaded properly.
  • Improved MTM playback.
  • make CONFIG=haiku for Haiku has been added.
  • Language bindings for FreeBASIC have been added (see libopenmpt/bindings/).

libopenmpt 0.2-beta15 (2015-10-31)

  • [Change] openmpt123: SDL2 is now supported and preferred to SDL1 if available with the Makefile build system.
  • [Bug] Emscripten support for older emscripten versions broke in -beta14. These are now supported again when using make CONFIG=emscripten-old.
  • [Bug] Fixed crashes in MED loader.
  • Playback improvements and loader fixes for MOD, MT2 and MED.

libopenmpt 0.2-beta14 (2015-09-13)

  • [Change] The C++ API example now uses the PortAudio C++ bindings instead of the C API.
  • [Change] Default compiler options for Emscripten have been changed to more closely match the Emscripten recommendations.
  • [Bug] Client code compilation with C89 compilers was broken in beta13.
  • [Bug] Test suite failed on certain Emscripten/node.js combinations.
  • [Bug] Fixed various crashes or hangs in DMF, OKT, PLM, IT and MPTM loaders.
  • Implemented error handling in the libopenmpt API examples.
  • Various playback improvements and fixes for OKT, IT and MOD.

libopenmpt 0.2-beta13 (2015-08-16)

  • [Change] The MSVC build system has been redone. Solutions are now located in build/vsVERSION/.
  • [Bug] get_current_channel_vu_left and get_current_channel_vu_right only return the volume of the front left and right channels now. get_current_channel_vu_rear_left and get_current_channel_vu_rear_right do now actually work and return non-zero values.
  • [Bug] Fix crashes and hangs in MED and MDL loaders and with some truncated compressed IT samples.
  • [Bug] Fix crash when playing extremely high-pitched samples.
  • Completed C and C++ documentation
  • Added new key for openmpt::module::get_metadata, "message_raw", which returns an empty string if there is no song message rather than a list of instrument names.
  • in_openmpt: Support for compiling with VS2008.
  • xmp-openmpt: Support for compiling with VS2008.
  • in_openmpt: Add a more readable file information window.

libopenmpt 0.2-beta12 (2015-04-19)

  • Playback fix when row delay effect is used together with offset command.
  • A couple of fixes for the seek.sync_samples=1 case.
  • IT compatibility fix for IT note delay.
  • ProTracker MOD playback compatibility improvement.

libopenmpt 0.2-beta11 (2015-04-18)

  • [Change] openmpt_stream_seek_func() now gets called with OPENMPT_STREAM_SEEK_SET, OPENMPT_STREAM_SEEK_CUR and OPENMPT_STREAM_SEEK_END whence parameter instead of SEEK_SET, SEEK_CUR and SEEK_END. These are defined to 0, 1 and 2 respectively which corresponds to the definition in all common C libraries. If your C library uses different constants, this theoretically breaks binary compatibility. The old libopenmpt code, however, never actually called the seek function, thus, there will be no problem in practice.
  • [Change] openmpt123: When both SDL1.2 and PortAudio are available, SDL is now the preferred backend because SDL is more widespread and better tested on all kinds of different platforms, and in general, SDL is just more reliable.
  • [Bug] libopenmpt now also compiles with GCC 4.3.
  • libopenmpt now supports PLM (Disorder Tracker 2) files.
  • Various playback improvements and fixes for IT, S3M, XM, MOD, PTM and 669 files.

libopenmpt 0.2-beta10 (2015-02-17)

  • [Change] Makefile configuration filenames changed from build/make/Makefile.config.* to build/make/config-*.mk.
  • [Change] libopenmpt for Android now supports unmo3 from un4seen. See build/android_ndk/README.AndroidNDK.txt for details.
  • [Bug] Fix out-of-bounds read in mixer code for ProTracker-compatible MOD files which was introduced back in r4223 / beta6.
  • Vibrato effect was too weak in beta8 and beta9 in IT linear slide mode.
  • Very small fine portamento was wrong in beta8 and beta9 in IT linear slide mode.
  • Tiny IT playback compatibility improvements.
  • STM playback improvements.

libopenmpt 0.2-beta9 (2014-12-21)

libopenmpt 0.2-beta8 (2014-12-21)

  • [Change] foo_openmpt: Settings are now accessible via foobar2000 advanced settings.
  • [Change] Autotools based build now supports libunmo3. Specify –enable-unmo3.
  • [Change] Support for dynamic loading of libunmo3 on MacOS X.
  • [Change] libopenmpt now uses libltld (from libtool) for dynamic loading of libunmo3 on all non-Windows platforms.
  • [Change] Support for older compilers:
    • GCC 4.1.x to 4.3.x (use make ANCIENT=1)
    • Microsoft Visual Studio 2008 (with latest Service Pack) (see build/vs2008)
  • [Change] libopenmpt_ext.hpp is now distributed by default. The API is still considered experimental and not guaranteed to stay API or ABI compatible.
  • [Change] xmp-openmpt / in_openmpt: No more libopenmpt_settings.dll. The settings dialog now uses a statically linked copy of MFC.
  • [Bug] The -autotools tarballs were not working at all.
  • Vastly improved MT2 loader.
  • Improved S3M playback compatibility.
  • Added openmpt::ext::interactive, an extension which adds a whole bunch of new functionality to change playback in some way or another.
  • Added possibility to sync sample playback when using openmpt::module::set_position_* by setting the ctl value seek.sync_samples=1
  • Support for "hidden" subsongs has been added. They are accessible through the same interface as ordinary subsongs, i.e. use openmpt::module::select_subsong to switch between any kind of subsongs.
  • All subsongs can now be played consecutively by passing -1 as the subsong index in openmpt::module::select_subsong.
  • Added documentation for a couple of more functions.

libopenmpt 0.2-beta7 (2014-09-07)

  • [Change] libopenmpt now has an GNU Autotools based build system (in addition to all previously supported ways of building libopenmpt). Autotools support is packaged separately as tarballs ending in -autotools.tar.gz.
  • [Bug] The distributed windows .zip file did not include pugixml.

  • [Regression] openmpt123: Support for writing WavPack (.wv) files has been removed.

    Reasoning:

    1. WavPack support was incomplete and did not include support for writing WavPack metadata at all.
    2. openmpt123 already supports libSndFile which can be used to write uncompressed lossless WAV files which can then be encoded to whatever format the user desires with other tools.

libopenmpt 0.2-beta6 (2014-09-06)

  • [Change] openmpt123: SDL is now also used by default if availble, in addition to PortAudio.
  • [Change] Support for emscripten is no longer experimental.
  • [Change] libopenmpt itself can now also be compiled with VS2008.
  • [Bug] Fix all known crashes on platforms that do not support unaligned memory access.
  • [Bug] openmpt123: Effect column was always missing in pattern display.

libopenmpt 0.2-beta5 (2014-06-15)

  • [Change] Add unmo3 support for non-Windows builds.
  • [Change] Namespace all internal functions in order to allow statically linking against libopenmpt without risking duplicate symbols.
  • [Change] Iconv is now completely optional and only used on Linux systems by default.
  • [Change] Added libopenmpt_example_c_stdout.c, an example without requiring PortAudio.
  • [Change] Add experimental support for building libopenmpt with emscripten.
  • [Bug] Fix ping-pong loop behaviour which broke in 0.2-beta3.
  • [Bug] Fix crashes when accessing invalid patterns through libopenmpt API.
  • [Bug] Makefile: Support building with missing optional dependencies without them being stated explicitely.
  • [Bug] openmpt123: Crash when quitting while playback is stopped.
  • [Bug] openmpt123: Crash when writing output to a file in interactive UI mode.
  • [Bug] openmpt123: Wrong FLAC output filename in –render mode.
  • Various smaller playback accuracy improvements.

libopenmpt 0.2-beta4 (2014-02-25)

  • [Bug] Makefile: Dependency tracking for the test suite did not work.

libopenmpt 0.2-beta3 (2014-02-21)

  • [Change] The test suite is now built by default with Makefile based builds. Use TEST=0 to skip building the tests. make check runs the test suite.
  • [Bug] Crash in MOD and XM loaders on architectures not supporting unaligned memory access.
  • [Bug] MMCMP, PP20 and XPK unpackers should now work on non-x86 hardware and implement proper bounds checking.
  • [Bug] openmpt_module_get_num_samples() returned the wrong value.
  • [Bug] in_openmpt: DSP plugins did not work properly.
  • [Bug] in_openmpt/xmp-openmpt: Setting name for stereo separation was misspelled. This version will revert your stereo separation settings to default.
  • [Bug] Crash when loading some corrupted modules with stereo samples.
  • Support building on Android NDK.
  • Avoid clicks in sample loops when using interpolation.
  • IT filters are now done in integer instead of floating point. This improves performance, especially on architectures with no or a slow FPU.
