VUMatcher Struct Reference

#include <MIDI_Inputs/MCU/VU.hpp>

Detailed Description

MIDI Input matcher for Mackie Control Universal VU meters.

In the Mackie Control Universal protocol, VU meters are updated using Channel Pressure events.
Each device (cable number) has eight VU meters for the eight tracks. Only MIDI channel 1 is used in the original protocol.

The format of the MIDI message is as follows:

Status Data 1
1101 cccc 0hhh llll

If the level is 0x0, the meter is at 0%, if it's 0xC, the meter is at 100%.
0xD is an invalid value.
0xE sets the overload indicator, and 0xF clears the overload indicator.
