Send Master Volume value to MIDI output

[augusj]

Hi,
I want to make a surface control with Arduino and I would like to get Master Volume value thru MIDI output as feedback. I can send new values to Master Volume but I I don't know how to get them form Tracktion

How can I do it?


Thanks

If I use Mackie Control Universal to send MIDI to Arduino, I can get feedback of Tracktion's Master Volume from MIDI message channel 9 Pitchbend's value:

Settings>Control Surfaces:

Update:

Midi message for Master Volume:

I already checked on T7's manual but I don't find any list with MIDI messages

How can I can get the list of T7 MIDI messages?
