Control performance mixer with midi?

I want to control the track levels with my midi controller (mpd26).

Now I use midi cc to control amp vol but this does not affect par locked steps.

My question:
Is it’s possible to control the track levels with midi?

yeah - honestly, discussed many times before - get ccs from os release notes or search here

Track level can now be controlled via MIDI CC 95 or MIDI NRPN (MSB=1, LSB=100).

Found it. Couldn’t find this in the manual or the forum. Thanks for pointing to the OS relase notes.
