This repo contains the config files to translate midi commands to Behringer X-Air compatible OSC commands. This config should mostly work for X32 mixers as well.
The code needs to be run on a computer that is connected to both the controller and the X-AIR mixer via midi, ethernet, or usb.
In my setup, I have midimonster running on a Raspberry pi 3, that is connected to the bcr2000 by USB. It then connects to the XR12 over wifi.
The config files should be straight forward to modify for other models and setups.
