This is my first real demo/in progress video of my pseudo educational, modular synth thing based on an ESP32.

The key aims are: cheap; DIY-buildable; tactile with actual wires and knobs; basics of an analog synth; means to hook up to solderless breadboards for experimenting.

It's a bit noisy, but it is largely working I think. The firmware for the ESP32 that drives it all still needs some work in places, but all the key elements seem to be there now. Also, ignore the last minute or so - I haven't decide how I'm going to combine the oscillators (if at all) yet, so there is quite a bit of aliasing going on when I try to do that right now.
