This is an effects patch for processing external gear. I usually do this with guitar (it’s a lot of the same fx!) but I’ve tweaked this for old synths – demo video is an Akai SG01v from 1996.
You’ll need VCV Pro for the poly phaser and flanger, I’ve swapped out a few things for free modules but nothing else does what those modules can.
You’ll need to tweak the threshold on the comparator to get different pitches from Rings, it’s very sensitive to input level. Also change the two quantisers to match whatever key you’re playing in.
