This component decodes modules, or music files combining both samples and sequence data and effects, using libopenmpt. Its version number is usually derived from the associated libopenmpt version, with a plus sign and trailing number if I add any extra commits following a library update. It supports files in the following formats: .MPTM, .MOD, .S3M, .XM, .IT, .669, .AMF, .AMS, .C67, .DBM, .DIGI, .DMF, .DSM, .DTM, .FAR, .IMF, .ICE, .J2B, .M15, .MDL, .MED, .MMS, .MT2, .MTM, .NST, .OKT, .PLM, .PSM, .PT36, .PTM, .SFX, .SFX2, .ST26, .STK, .STM, .STP, .ULT, .WOW, .GDM, .MUS, .FMT, SymMOD, DSym, and .STX. It also supports Ian Luck's .MO3 compressed format with MP3, Ogg Vorbis, or ADPCM samples, and it also supports arbitrary archive formats with the extensions of .MDZ, .MDR, .S3Z, .S3R, .XMZ, .ITZ, or .MPTMZ, assuming foobar2000's Archive Support plugin is installed, or any other archive plugin.

Note: The included "sinc" resampler is equivalent to the OpenMPT software's "sinc + lowpass", aka sinc plus anti-aliasing filter. The option to disable this filter is not currently exposed in the libOpenMPT API, and even if it were, it would be an implementation detail only relevant to the "sinc" resampling filter size.

- Ping-pong sample loops sometimes stopped playing at the end of the loop.
- Pitch / Pan Separation and Random Variation instrument properties were not resetting properly when seeking, potentially causing instruments to be played e.g. at a vastly different pan position compared to playing the module continuously.
- MED: Stereo samples were not imported correctly.
- zlib: Update to v1.2.12 (2022-03-27).
