The files saved by the ProTracker 2 editor are very large, and the music playing routine supplied by BZYK is rather slow. This program solves those problems, by converting a large file into a much smaller one which can be interpreted very quickly.

The routine which plays these music files runs in (usually much less than) half the time it takes the standard E-Tracker music player to run, so it is very suitable for use in demos and games where cpu power needs to be conserved.
