PD Guitar Pedal By Noah Laudolff This patch can run on its own, but I run it on a raspberry pi for a real guitar pedal experience. Write some cheeky python to run the main program on startup. I used a Teensy 3.6 to handle the knobs and an Audio Injector Sound Card for the Audio IO. The pins are as follows: FUNCTION PIN# POTS: Input gain 23 Delay time 22 Delay decay 21 Rev wet 20 Rev dry 19 Trem rate 18 Trem depth 17 Dist gain 16 Dist cutoff 15 Comp gain 14 Comp thresh A22 Comp ratio A21 High 39 Med 38 Low 37 SWITCHES On/off 36 Delay 35 Reverb 34 Tremolo 33 Distortion 31 Compressor 32 LIGHTS On/off 2 delay 3 Reverb 4 Tremolo 5 Distortion 6 Compressor 7
