Exist. Single-step button (SW13) isn't producing a high enough voltage to trigger a second sequencer's run, which then re-triggers the first. - Trigger out - could be other values, ceramic may work, test debouncing. Maybe enlarge footprint if needed. Subject: [PATCH 09/13] Notes from MK's PCB livestream Footprints: - avoid non-circular holes in footprints whenever possible; some fabs charge more for ovals - make power connection traces larger; MK uses a ground plane.
