I started building a fully programmable analog polyphonic synthesizer - again. In this video I’m going to look at the main components and give a first outlook on the hardware. Please subscribe and like and get notified about upcoming videos on my channel!

There is a small batch of Voice Card PCBs on Tindie for sale in case you are interested and would like to support my channel: https://www.tindie.com/products/polykit/full-voice-card-for-a-polyphonic-synthesizer-pcb
