Add hard sync to schematic, laid out PCB with exploratory 8hp layout 2x Sockets, all three pins need wires: - clk in - glide in (sleeve and normal both GND 6x Sockets, 2pin: - all step switches (all go to same bus run/stop 2x Pushbutton switches, all 2pin: - all step switches (all go to same bus 2x Pushbutton switches, all 2pin: - reset in - pause in - glide in (sleeve and normal both GND 6x Sockets, 2pin: - step - reset Pots, 3-pin: - Glide attenuator (B10k) (join two left pins from below) - Clock In Normal - 1k to U2-8 (AND NOT short to U2-10 Clock Rate - variable resist +6k between U2-8 and U2-9 - Reset Sw - when pressed, short +12V and Reset In socket Reset Socket to U3-3 = capacitor measurement roughly 15nF (has a resistor as well - Once/Cont 11 Toggle Switches, 2pin: - reset Pots, 3-pin: - Glide attenuator (B10k) (join two left pins from below Clock rate goes down when resistance goes up, opposite to expectation.
