Bouncing Ball (ENV-B as LFO to VCO-B)
A bouncing ball patch.
This patch is designed to simulate the physics of a bouncing ball. When you drop a ball, it loses energy with each bounce, causing the time between bounces to decrease. So the goal is to create a ratchet that ramps up its speed.
The basic patch uses a ramp wave LFO to modulate the speed of a cycling envelope.
In this implementation ENV-B is being used as an LFO to modulate the pitch of VCO-B, which is triggering ENV-A. Envelope-B Rise/Rate slider controls the overall length of the bouncing. VCO-B pitch controls the bounce speed.

The Aphex track. I don’t know how he did it. He might have programmed it manually, or used LFOs from a synth to trigger a sampler?
