MIDI Tracker 1.0 by Saga Musix
My first attempt at writing a tracker in 2004. QuickBasic 4.5 + MS-DOS + MIDI
(via MPU-401-compatible interface). I never really managed to write a full track
with it, and instead "ported" some of the sketches I wrote in it to
ModPlug Tracker for use in one of my early games.
