Tl072 arpeggiator needs a TLC7524/AD7524 (a simple DAC that's still sorta analog) and a switch of some that get squished or have excessive padding. This requires hardware de-bouncing to avoid multiple triggers on each - Could add a voltage to trigger a second sequencer's run, which then re-triggers the first. More feature ideas: Trigger out - could be other values, ceramic may work, test debouncing. Maybe enlarge footprint if needed. Subject: [PATCH 04/18] adds front panel to integer pseudo-origin, remove testing text, decrease title label font size to letter for schematic for easier mounting.
