Maths simulates a bouncing-ball physics envelope by chaining two channels with decaying amplitude

Procedure L3Craft E · Modular, Eurorack, grooveboxes & dawless

The Bouncing Ball patch on Maths uses CH.1 with RISE full CCW and a moderate FALL to generate successively triggered envelopes, patching CH.1 EOR to CH.4 CYCLE IN. CH.4 produces an amplitude envelope that controls a VCA or LPG. A gate or trigger starts CH.1. Adjusting CH.4 RISE and FALL varies bounce timing. The patch models a bouncing ball: each bounce is faster and lower amplitude than the previous. This demonstrates Maths’ ability to create complex physics-inspired modulation without additional modules.

Examples

CH.1: RISE full CCW, FALL to 3:00, linear response. CH.4: RISE full CCW, FALL to 11:00, linear response. CH.1 EOR → CH.4 CYCLE IN. Gate/trigger → CH.1 TRIG IN. CH.4 output → VCA CV.

Assessment

What patch connection causes the bouncing-ball behavior to be self-sustaining after an initial trigger?
