Bouncing Ball (VCO-B to ENV-B as LFO)
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.
This implementation uses VCO-B and ENV-B both as LFOs. VCO-B controls the rate of ENV-B. Envelope-B Rise/Rate slider controls the bounce speed. OSC-B pitch controls the overall length of the bouncing.
Some combinations of ENV-B fall and VCO-A pitch may cause irregular clicking. Hard sync VCO-A to ENV-B to ensure the clicks always occur on the attack.

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?
