cross-platform C++ and C library to decode tracked music files

OpenMPT and libopenmpt

This repository contains OpenMPT, a free Windows/Wine-based tracker and libopenmpt, a library to render tracker music (MOD, XM, S3M, IT MPTM and dozens of other legacy formats) to a PCM audio stream. libopenmpt is directly based on OpenMPT, offering the same playback quality and format support, and development of the two happens in parallel.

How to compile


  • Supported Visual Studio versions:
    • Visual Studio 2019, and 2022 Community/Professional/Enterprise

      To compile the project, open build/vsVERSIONwin7/OpenMPT.sln (VERSION being 2019, or 2022) and hit the compile button. Other target systems can be found in the vs2019*, and vs2022* sibling folders.

      Note that you have to build the PluginBridge and PluginBridgeLegacy projects manually for architectures other than the one you are building OpenMPT for, as Visual Studio only builds one architecture configuration at a time.

      Please note that we do not support building with a later Visual Studio installation with an earlier compiler version. This is because, while later Visual Studio versions allow installing earlier compilers to be available via the later version's environment, in this configuration, the earlier compiler will still use the later C and C++ runtime's headers and implementation, which significantly increases the matrix of possible configurations to test.

    • Visual Studio 2017 XP targeting toolset
  • OpenMPT requires the compile host system to be Windows 8.1 (or later) amd64, or Windows 11 (or later) ARM64.
  • In order to build OpenMPT for Windows XP, the Visual Studio 2017 XP targeting toolset as well as the Windows 8.1 SDK need to be installed. The SDK is optionally included with Visual Studio 2017, but must be separately installed with later Visual Studio versions.

    The Windows 8.1 SDK is available from or directly from

  • Microsoft Foundation Classes (MFC) are required to build OpenMPT.
