DIY digital controlled analog POLYPHONIC SYNTHESIZER

Over the last year I built this digitally controlled analog polyphonic synthesizer. All schematics and PCBs I created myself (except of the chorus). Please subscribe and like and get notified about upcoming videos on my channel. It was harder than I thought to finish this project but I learned how to layout PCBs and a lot about vintage synthesizers. 0:00 - Voice Stacking/Detuning 0:34 - Envelope Generator 1:55 - Filter 3:10 - Filter with Envelope Generator 5:38 - PWM 6:48 - Filter Resonance with LFO 7:26 - PWM with LFO 8:53 - Filter Cutoff with LFO 10:28 - Arpeggio 13:45 - Chorus 15:11 - Arpeggio 18:24 - Arpeggio All schematics and PCB layouts can be found on https://github.com/polykit GitHub: https://github.com/polykit Mastodon: https://chaos.social/@polykit Specs are: - 6 voice polyphonic analog DCO based on Juno 106 using a single Raspberry Pi Pico - Sawtooth and square signal - PWM control (manual, LFO) - Voice stacking and detuning - MIDI input - MIDI pitch bend - MIDI portam
