BankStep

BankStep is a 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). Otherwise, BankStep functionally emulates a monster bank of hardware sequencers and support modules just as it might sit on top of a big Moog - or your soft synth, MIDI module or sound card.
