Six evil patches

Rendered in test/out/ex*.wav by the same engine and the same panel mapping the firmware runs. Knob positions are clock faces: 7:00 is fully counter-clockwise, 12:00 is centre, 5:00 is fully clockwise. "S1"–"S4" means hold the button and turn knob 1–4. Routing is the number of taps after power-on. Untouched shift knobs stay at their defaults: ratio 1:1, sine, symmetry and fine at noon.

1 · Reactor hum

A low drone whose feedback breathes in and out.

Toggle up, routing 0. Pitch 8:40, FLESH 10:30, LEGION 8:10, S1 8:20 (ratio ½), S3 1:30. Rock MALICE slowly between 8:00 and 12:00.

2 · Lorenz growl

A chaotic modulator in audio range, like an engine that won't idle.

Toggle down, routing 1. Pitch 9:30, S1 1:10, S2 4:00 (Lorenz). Ease FLESH from 11:00 to 1:00.

3 · Chaos bells

Inharmonic struck metal that gets more unhinged as it goes.

Toggle up, routing 2. Pitch 12:00, FLESH 7:30, S1 12:00 (ratio 3). Sequencer into CV_5, a fast decaying envelope (0–2.5 V) into CV_6 (FLESH), trigger both together. Turn MALICE from 11:30 to 3:30.

4 · Feedback scream

The pitch dives while feedback tears into noise.

Toggle up, routing 0. FLESH 1:00, S1 10:10 (ratio 1.5), S3 10:00. Together, sweep pitch from 4:10 to 9:30 and MALICE from 12:00 to 5:00.

5 · Possession

Everything rising, then the modulator turns chaotic.

Toggle up, routing 3. Pitch 10:20, LEGION 10:00, S1 11:05 (ratio 2), S2 2:00 (square), S3 2:30. Sweep FLESH from 11:30 to 4:00 and MALICE from 9:30 to 3:30, then flip S2 to 4:00 (Lorenz) halfway.

6 · Legion

One voice becomes a swarm while the fold opens.

Toggle up, routing 0. Pitch 8:40, MALICE 9:00. Sweep LEGION from 8:30 to 5:00 and FLESH from 10:00 to 1:00.
