MystrixFSJI is an application for MatrixOS to turn the Mystrix into a controller for Free-style Just Intonation. The key features to support this goal are use of System Exclusive (SysEx) messages under the MIDI Tuning Standard (MTS) to convey tuning information over MIDI, and a custom-made UI. Future objectives include transposition of the grid-shaped UI, and easy modulation into other keys using another controller.

To add this project to your MatrixOS firmware build:

1. Add this repository as a submodule in MatrixOS/applications/MystrixFSJI
2. Add #include "applications/MystrixFSJI/FSJI.h" in the USER APPLICATION section of Applications.h
