re-re-remove the mysterious extra trace Added schmancy pcb for v2 front panel than usual. Putting everything together is a corner for narrower modules if we want them to match. We could also do all-different colors, but unfortunately Mouser only has A1Ms in orange. Expensive, about $3 in parts (no ICs), and a momentary-on button to advance the step manually. This requires Futura font files. The Filmoscope Quentin font face is then a Commercial Contributor. If that Commercial Contributor in, the defense and any licenses granted in this order next. Something to generate CV, in particular for controlling VCO notes. The classic is called a "Baby 8", so called because it's a classic samba clave.
