Trig
Karplus Strong/ delay based percussion synth triggered by acoustic transients
Percussive hits on a guitar (or other instrument) trigger percussive sounds, synthesised using a Karplus Strong/ delay based approach with a noise burst, filter, delay, filter and feedback loop.
Here’s a quick demo:
| Control | Parameter | Left LED | Right LED |
|---|---|---|---|
| Left knob | Input threshold for trigger | ||
| Right knob | Delay length (affects pitch) | ||
| Encoder button (single click) | Toggle delay or noise filter adjustment | Red = delay filter, green = noise filter | |
| Encoder button (double click) | |||
| Encoder | Delay or noise filter amount | Red = delay filter, green = noise filter | |
| Left button | |||
| Right button |
