MIDI Beat Pad x Keyboard

Created by [Kaitlyn Z] • Started on June 02, 2025

A portable and modular custom MIDI controller, which combines a Beat Pad and a Keyboard!

June 2nd: Research

  • Looked at different designs for midi controllers with a 16 pad beatpad and 2 octave keyboard
  • Found the Alexis V125 Alexis V125 Image
  • Researched the functions of different buttons on a MIDI controller --> turns out they are all assignable
  • Decided to use an RPi Pico for a custom PCB
  • Researched ways to do velocity and pressure sensing
    • Will likely use 2 buttons or IR sensors and measure the time difference to calculate velocity
  • Thought about ways to make the design modular
    • Will likely use a magnet

Total time spent: ~3.5 hours
