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 |
1101
(or 0xD
) is the status for Channel Pressure events
cccc
is the MIDI channel [0-15]
hhh
is the track index [0-7]
llll
is the level of the VU meter
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.
