Midui - open source MIDI pad

thingiverse

This is an open-source MIDI pad based on Adafruit's Mini UNTZtrument. The primary goal of this project was to create a two-pad MIDI controller compatible with Trellis PCBs. Starting from Mini UNTZtrument, I endeavored to redesign it and improve it further. Initially, I added an extra Trellis PCB to enable the user to control each pad with one hand, thus simplifying gameplay and control. In addition, I replaced normal potentiometers with sliding ones to facilitate the adjustment of mapped values using thumbs only. Lastly, I sought a simpler assembly process and enhanced finish. To this end, I relocated counterbored holes to the base's bottom side, ensuring one-way assembly while concealing all screws simultaneously. This is still an ongoing project, so it's recommended to wait for future updates with improved tolerances for a smooth fit.

Note that you should only use the two holes near the side and the one further towards attaching the Arduino. Do not utilize all of them; they don't fit properly. 1x Top.stl - Rotate it 180 degrees before slicing for correct orientation. 2x Pad_holder.stl - These attach Trellis PCBs, which are symmetric to facilitate balanced placement. 4x Pot_encl.stl - Print these four enclosures as you'll need them for your four 10k sliding potentiometers. Sand them a bit; I'm currently refining the process
