Bouncing Ball with Pitch Modulation (ENV-B as LFO to LFO)
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. This implementation uses VCO-B setup as an LFO. VCO-B controls the rate of ENV-B, which triggers ENV-A. Envelope-B Rise/Rate slider controls the overall length of the bouncing. The LFO rate dial controls how fast the bounces will go.
ENV-B is also modulating the pitch of VCO-B.

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?
