My final module has 2 jacks for Gate, 2 jacks for Trigger, a Gate LED, a Trigger LED, a CV out and a Clock In jack. The module uses a ssd1306 display and a rotary encoder to control.

My version of the code was modified for the above. Also the code previous had a resolution of 4 for the encoder, but my encoders needed a resolution of 2.

All of the 3.5mm mono jacks seem to be slightly different dimensions for the black plastic. The actual metal jack seems to be standard. This stl is customized for the black jack that has the Metal shield wrapped around it as s
