More Atari-Midi Freeware: MIDIGEN
Petra Wolf and Joker of the "Klang Piraten" have released an Algorithmic Midi application called MidiGen. There are no docs yet except for a general description, but by clicking into the various fields and boxes you can get some tremendous output.I will soon have screen shots and perhaps a tutorial when I add it to the Klang Piraten page on TAMW, but in the meantime, check out this very unique application.
