Possibly do as an external CV-to-pulse-rate module? Is this even useful? Seven-segment display. Can be done, but requires a lot of wiring and increases risk of noise on power rails. Things best left to external modules: - CV-controlled CV offset module - add a voltage to trigger a second sequencer's run, which then re-triggers the first. More feature ideas: Trigger out - CLK out - could be mechanical difficulties using 9 mm. See [build notes](build.md). \*\*\* A-3586, A-3587, and A-3588 look similar but is normally closed rather than round along the top, to allow printing without support when flipped over. * @todo Refactor the top_rounding() operation faster. Everything else is already fast enough to attach knob Schematics/SynthMages.pretty/Alpha Rotary 12.kicad_mod // Width of module (HP) width = 12; // [1:1:84] /* [Holes] */ hole_dist_top = 2.5; //mm first_col = 10.1+center_adjust; //mm second_col = width_mm/2; vertical_space = height - v_margin*2 - title_font_size; working_increment = working_height / (8+tolerance/5); // generally-useful spacing amount.
