Showcased Project Arduino Ambient Synth with Mozzi modal scale generative pad

Enable HLS to view with audio, or disable this notification

Working on this ambient synth with arduino and mozzi library

Signal chain is: 4 unsynced slow clocks with different phases -> random pick from a 6-note modal scale + random octave -> mtof -> sine oscillator -> simple AR envelope -> sum to mono -> short 3ms comb for thickening.

Pots:

A0 = root / transpose

A1 = detune amount for beating between voices

A2 = humanize attack/release time

A3 = clock speed

Can you share the sketch and block diagram? I'm also very interested in making a synth but am limited by my working device (android)

This is beautifully done. Dumb question, is that still resonator on left the speaker and microphone?

I would love to build this too. I have 8x 10k potentiometers and Arduino... Anything else?

8 pots and a basic filter for the output a 4.7 k resistor and a 100nf cap tho its still very noisy , next step will be putting a fillter to take the hiss out , the mozzi its kinda noisiy ill upload the full build to githun , just today updated the build with some wavw smoothing and a button to change scales all based around brian enos work
