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, and .GDM. 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.

• The retrigger effect didn’t work correctly for OPL instruments in some cases depending on the chosen output sample rate.
• S3M: Emulate IT short sample retrigger quirk in S3M files saved with Impulse Tracker and Schism Tracker.
• ProTracker 3.6 doesn’t support sample swapping. It is now disabled when loading a ProTracker 3.6 IFF module.
• Some files with “hidden” garbage patterns were not played correctly since libopenmpt 0.5.3.
• MOD: E9x retrigger now works the same way as in ProTracker 2.
• MDL: Improve auto-vibrato accuracy.
• 669: Reject files that contain any pattern tempo higher than 15.
• Reduce memory consumption of malformed XPK-compressed files.
• mpg123: Update to v1.27.2 (2021-05-08).
