EZ MIDI MCP

Presets, MIDI, and an OLED display for your pedal. Run it on your own hardware.

Built on EZ MIDI 3.0 and running on an STM32 microcontroller, EZ MIDI MCP controls up to 8 digital pots. No customization needed.

Building pedals to sell? Skip the pre-flashed chips. Source your own microcontrollers, flash the code yourself, and activate with the EZ MIDI activation board. Your supply chain, your call. Licensing is priced to keep your margins healthy. Need something specific? We’ll write code to your exact specifications.

Just tinkering? The evaluation version is fully featured and free. It runs for 2 hours between power-ups.

EZ-MIDI-MCP code – This is the code to flash onto your STM32F103C8

EZ MIDI Kicad demo board – You can use this to adapt your own designs. This has not been tested, but was adapted from the EZ MIDI Programmer board. Some components like the OLED display, EEPROM and control pots are off board. All components are through hole except the STM32F103. These can be soldered by hand with flux and a little patience.
