4 Valley Interzone SHish voices with a MIDI-4 triggering to get 4 voices. It’d be great to add an extra Oscillator, but i think it’s OK for now.
The demo video attached is not the best demo of this patch, as there’s only one part among 6 synths playing plus guitars, but it’s a real scenario usage.
I’ll finish the 4SH+ soon & upload here with a better example.
