8xyy - Tralala x.yy prealpha versions, built from svn, before the first release identify as version 0.00 (i.e.the user can override the value of the Cwt/v header by the -w command-line switch or the #TRACKER-VERSION command in the input file)

5xyy - OpenMPT x.yy - lower two bytes of version number are stored in the 'reserved' header field starting from OpenMPT 1.29.10.00 in compatible mode (otherwise OpenMPT song extensions are used as before).1xyy - Schism Tracker x.yy up to Schism Tracker v0.50, later versions encode a timestamp in the version number - see Schism Tracker’s version.c or OpenMPT’s Load_it.cpp for a version not relying on the C runtime library (since localtime is not guaranteed to be thread-safe).0xyy - Impulse Tracker x.yy - Many other trackers, like ModPlug Tracker, disguise as various versions of Impulse Tracker, so this is not a reliable way to tell if a file was really made with Impulse Tracker.The following custom tracker IDs (read as little-endian hexadecimal numbers) are known to be found in the Cwt/v field: The IT header contains a field, Cwt/v, which is used to identify the application that was used to create the file. 6 Proposed way to store compressed stereo samples.
