ESP32-S3 PolySynth - Work in progress

video upload by Bad Dog Designs

"This is a fully functioning Polysynth using an ESP32-S3 to model the audio in real time, from an initial single Sine wavetable calculated on power up. The control panels for the oscillators and common controls all use CAN bus to communicate parameter changes to the audio engine - rather than wiring up a lot of IO, it just sends a message like 'Change oscillator 3 to Sawtooth'

Basic spec so far:

6 oscillators in 3 pairs that have Sine / Triangle / Saw / Pulse / Noise and Chaos waveforms. There are then independent wave folding modifiers and Sample and hold modifiers. Each oscillator pair can also be hard sync'd to it's partner for mono use, or FM modulated.

Common controls have ADRS envelope control, High / Low / Band pass filter with Envelope and tracking control. Ring modulator and Play mode selector for Unison / Duo / Poly. 2 re-triggerable LFO's with delay.

Currently working on the routing section that will allow pretty well anything to modulate anything else stored as separate routes - up to 12 routes can be applied at once. Then patch storage and recall, and hopefully some nice analogue FX at the end.

In the clip, all the audio is straight out the back of the DAC with no processing or FX."

61-key, 16-voice polyphonic, 15-part multitimbral digital synthesizer that uses additive synthesis, rather than the more common subtractive synthesis. It is known for complex, unique sounds, particularly pads and digital textures, achieved by manipulating 63 harmonics for each of its two sound sources."
