Project came together well, I used slightly different sliders and remixed the knobs. I am using https://www.midi-mixer.com/ to control the audio levels and buttons, its great so far! I used a Teensy 3 as the controller, and soldered the wires right to the board. I had to use hot glue on the sliders and the controller to hold things in place. The washers to screw into are hard to get into their spot, but plyers helped.
