This is using the Circuitbenders pcb with mods to the voices. I’ve had the board for a while and it’s been a project that I’ve come back to in between other projects. When I bought the pcb it was always the intention to see what modifications I could do to each of the voices. The kick and rimshot circuits were breadboarded and ideas tried out there but as the hihat and snare use a joint noise circuit I assembled part of the circuits on the pcb and then ran flying wires to the breadboard to try ideas. I’ve added circuitry to the hihat to give an open/closed effect as the original circuit had a set decay.
