SoftStep MIDI Algorithmic Composer (Basic) v1.3 is a complete, MIDI step sequencer. Patterned after analog sequencers, the program provides a variety of fractal, chaos, probability, and numerical functions for music generatation.

BankStep 2.1 Software emulation of hardware bank sequencers found in the big analog synthesizers, that produce control for the sound but not the sound itself. Instead of analog control voltages BankStep produces MIDI (and can make standard MIDI music files).
