From the project

An embedded C++ firmware and KiCad hardware project that turns a Nintendo 64 controller into a fully-functional MIDI instrument, inspired by the ocarina gameplay mechanic of The Legend of Zelda: Ocarina of Time.

An embedded C++ firmware and KiCad hardware project that turns a Nintendo 64 controller into a fully-functional MIDI instrument, inspired by the ocarina gameplay mechanic of The Legend of Zelda: Ocarina of Time.

The RP2040 reads button and joystick inputs from up to four simultaneous N64 controllers via the Joybus protocol, maps them to MIDI notes and control messages, and outputs standard 5-pin DIN MIDI at 31 250 baud — ready to plug into any synthesiser, DAW, or MIDI-capable instrument.

64-controller to midi converter: common questions

What microcontroller does the 64-controller to midi converter use?

The 64-controller to midi converter is built around the RP2040, from the RP2040/RP2350 family.

How many components are on the 64-controller to midi converter?

34 components, from 15 distinct parts. The full bill of materials is listed on this page.

Where can I download the 64-controller to midi converter design files?

From the turboOrange/64-controller-to-midi-converter repository on GitHub, which has the schematic; the links under Design files point to each one.

Can I use the 64-controller to midi converter design in my own project?

The repository has no license, so all rights stay with turboOrange. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the 64-controller to midi converter without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
