Question

the VCA button on the FP8 just doesn't seem to work in Pro Tools at all to highlight the VCA tracks in my session. Is this a feature that is supposed to work in HUI mode with Pro Tools?

Answer 1

The VCA button will not have any functionality as stated in the FaderPort 8 manual in section 3.7:

"The Mix Management buttons are not available within the HUI protocol and so will not function in ProTools. These functions are available in Mackie Control and Studio One modes in other DAW applications"
