Hi Alex , thanks for your support,
“Pro Tools allows a DCA track to be controlled by a MIDI controller.”
in the reference guide of pro tools there no info about limitation of VCA (i am sorry from pro tools this tracks are called vca not DCA)
“try using the bank up and down to view the DCA on the MIDI faders.”
i had soft button 7 and 8 assigned for bank up and down and there’s no vca from pro tools to be controlled.
