Interesting, thanks for sharing. I'd be interested in experimenting a hybrid approach in which the microcontroller takes MIDI in then generates basic waves (saw, square, sine etc) to keep resource consumption as low as possible while maximizing poliphony (layering with detune, etc), then leaving to analog circuitry noise generation, filtering, enevelopes etc. It would make things more complicated hardware-wise but I'm sure the sound would improve significantly, at least for us old beards who still love analog synths from the 70s.
- nitrogen 6y agoI have an Ensoniq SQ-80 synthesizer that did something like that. A microcontroller generates 8 channels of sounds from a PCM wavetable, and those are fed into 8 analog filters before mixing down to stereo. But all of the waveforms and envelopes were digital.
