About this project

DOOM OS turns the SP-404MK2 into something closer to a full groovebox. Beyond the sequencer and piano roll, it adds live recording with quantize and swing, a mixer with level meters, side chaining, a three-band EQ, an arpeggiator and undo.

A help mode shows what each button does, and there's a separate full manual. The project offers a web patcher as its quick install route.
