He designed the 3D-printable enclosure in SketchUp to hold 12 potentiometers, two buttons, a 16-channel analog multiplexer, and a Raspberry Pi Pico RP2040. He coded it in CircuitPython to send UART MIDI over TRS cable, so that parameters can be controlled on the M8. One particularly cool feature he coded is the ability to parameter lock (record and automate) the value of any knob position over time. The code is available on the build page.
It was a pretty fun project and a first physical device build that I’ve actually finished (I have started a lot of them!) where I have designed, built and coded everything myself.
Great looking build!

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
