A project log for Polyphonic Touch PCB Piano
Pretty much exactly what the title describes, can play 4 channels of polyphonic squarewaves at once triggered by 13 capacitive touch keys
To start off, thanks to JLCPCB for sponsoring this project and providing the pcbs I designed. JLCPCB Prototype for $2 (Any Color): https://jlcpcb.com/DYE
So what do the polyphonic waveforms actually look like when playing four different notes?
