XR Meters

A simple example library to demonstrate how to get @music-tribe Behringer/Midas X Air XR/MR Series mixer's meter data, in Node.JS

It's useful for electron applications etc. but not intended to be used as a standalone package or repository - just something you might copy and paste bits of, or even just be inspired by.

Parameters.txt also contains all the parameters and commands for OSC with this series of Mixers, from the firmware provided by Behringer.

Output Format

All values are in decibels, and are signed. Minimum values tend to be around -100, max is +10 (the limit of the headroom on the device)
