Sustain2Midi

This project is a simple Sustain pedal to midi note converter based on a raspberry pi pico board.

Features

• Dirt cheap (all you need is a mono jack socket and a raspberry pi pico)
• Sends note on/off
• Note number can be changed easily by sending a midi note to the device.
• (Optional) Use a WS2812 NeoPixel to show the state and midi note value via colour (I use this module but I think any one should work) – disable this using the SUS2MIDI_NEOPIXEL build flag in the .ini file.

Dependencies

You need to have platformio installed to make use of this. I prefer using the command line version.

Install it on MacOS by running homebrew:

brew install platformio

Compiling and uploading
