In the ‘50s, a film named Forbidden Planet featured the Krell creatures, and their theme inspired Todd Barton to build a patch, the Krell patch, as an interpretation of the Krell creatures’ music.
The essence of this patch is a main looping envelope\function, of which the rise and fall times are modulated by 2 more looping envelopes, and their rise and fall times are also modulated by a smooth random signal. The main envelope is then controlling the level of an oscillator, but also triggering a s&h unit via its end of cycle output, which then modulates the pitch of the oscillator. The result is so unique and alive, ever-changing, and it’s almost like it’s breathing.
In this video, I build a Krell patch, from scratch, and also adding to it, developing it further.
