Bias FX midi controller

I created a MIDI controller to edit/control my guitar and effects in Bias FX 2 without having to use the mouse all the time.

It needs 5 potentiometers (I've set them up to control Gain, Bass, Mids, Treble and Presence) and 5 small momentary push buttons (I use them for preset selection, bank selection and one button to enable drives/boost/FX) and an Arduino Leonardo or similar.

The top case is printed face down without supports, and the top is supposed to be glued after you've made sure everything is working. I just use some rubber stickers to keep them together in case I want to open it up later.

The 5 pots are wired to common ground, common 5V and analog pins 0-4, the buttons are wired to common ground and pins 1-5. The sketch uses the Control Surface library here: https://github.com/tttapa/Control-Surface

Arduino sketch:


#include

USBMIDI_Interface midi;

// The potentiometers are sharing 5V and Ground, the middle pin of each pot goes to analog 0 - 4
