This is a control surface for the Modal CRAFTrhythm. Starting at the top, the monochrome knobs work to edit the selected track. The track buttons 1-8 will turn gray when a track is selected for editing. The sample can be changed to any sample in memory, a pitch mode can be selected, and the pitch, amp, and filter envelopes can be edited. In the rainbow section, each track has knobs for tuning (per the track’s pitch mode setting), pan, filter cutoff, and resonance. Each track has a level fader and a trigger pad. Tip: if you sequence the CRAFTrhythm from AUM, route the sequencer’s MIDI out into Surface Builder. The pads will react when that track is triggered. V1.1 update – minor UI changes; functional changes to the track selection buttons. V1.2 update – minor UI change.
