Yes I think that’s clear !
I also think that’s clear that you are trying to rewrite something that is already coded elsewhere in Logelloop…
Unfortunately we will not change the trackVolume behavior as it would need some time, and we have plenty of important thing to do before, and you can use the regular way of mapping midi controller to a fader if you need the reach to modify functionality.
That’s probably not what you need, but, maybe this may help you :
SendData item 5 midimode 3
This is the way to set “reach to modify” in the matrix dial (0 = normal, 1 = mc, 2 = push, 3 = reach modify)
