Cool project! Why do you call it digital though? The oscillator is analog

[kzalesak]

Well, the oscillator is a Schmitt trigger. The trigger waits for a capacitor to discharge pas a hysteresis point, but uses discrete voltage levels to switch. So, maybe semi-analog?

I would consider a synth digital if it contains a DAC or at least a DCO, otherwise you'd say that relaxation oscilators are analog too :)
