Custom MIDI Controller (Copper)

I’m building myself a MIDI controller to be used with Ableton. I couldn’t find a XY potentiometer apart from trackpads which wouldn’t be useful since I need a more tactile control, so I came up with my own solution (bottom). The round push buttons are used for viewing and controlling the track. The upper buttons control the delay and reverb. Three of these interfaces will be built alongside each other so that I will be able to control 3 channels at once.
