A trill, generally three very fast notes on repique/caixa, two or three for surdos

row_2 = row_1 + vertical_space/7; row_7 = row_6 + vertical_space/7; row_7 = row_6 + vertical_space/7; row_6 = row_5 + vertical_space/7; row_5 = row_4 + vertical_space/7; row_6 = row_5 + vertical_space/7; row_3 = row_2 + vertical_space/7; row_7 = row_6 + vertical_space/7; row_6 = row_5 + vertical_space/7; row_3 = working_increment*2 + row_1; working_increment = working_height / (8+tolerance/5); // generally-useful spacing amount for vertical columns of stuff col_left = thickness * 2; right_rib_x = width_mm - thickness*2; // pcb_holder(h=10, l=top_row-rail_clearance*2-15-thickness, th=1.15, wall_thickness=1); // lower h-rib reinforcer ## Photos ### Photos ## Documentation: ### Documentation: * [Schematic](Docs/precadsr.pdf) * PCB layout: make power connection traces larger; MK uses a CA3080 OTA, an expensive and rare chip these days ($3/ea on amazon, maybe fakes) VCA MK's VCA Everything by Hagiwo (quantizer, filters, noisemakers, etc) MIDI-to-CV, either over USB or directly over 5-pin DIN (with optoisolator) What we build next? Pretty confident we do these in this set.
