At last: the Krell Patch on a Frap Tools modular system!

It's time to confront ourselves with a pinnacle of modular synth techniques: Todd Barton's Krell Patch.

Inspired by Bebe and Louis Barron's soundtrack for the 1956 sci-fi film "Forbidden Planet", this patch revolves around a "modulation feedback": a single LFO drives the whole patch and triggers many S&H circuits that generate random voltages, which, in turn, constantly modulate the LFO speed and shape.

Original track from the film score:    • Ancient Krell Music
