A free web cheat sheet of every EP-133 K.O. II shortcut, organised by what you're doing: sampling, chop, keys and scales, the step sequencer and timing, patterns and scenes, song mode, FX, MIDI and sync, and system setup. It's searchable, updated for OS 2.5 with new combos flagged, and a quick refresher for anyone coming back to the K.O. II after a break.
