Quieter, unaccented note

A trill, generally three very fast notes on repique/caixa, two or three for surdos Add schematic, start on PCB Checkpoint after converting most things to SMD Latest commits for file Panels/10_step_seq.png Latest commits for file Fireball/Fireball.kicad_sch Added input resistor for sync; placed everything on PCB Added hard sync input. CV in to pause the sequence. Probably can't do, or impractical: - CV-controlled clock. Presumably the CV in to pause the sequence. Probably can't do, or impractical: CV-controlled clock. Presumably the CV in that pauses the clock oscillilator an external CV-to-pulse-rate module? Is this even useful? - Seven-segment display. Can be done with a wire. Assembly Notes: Do not assume anything works! Repo uses submodules aoKicad and Kosmo_panel, which provide.
