Pro Audio Support

Q:
After updating to Pro Tools 5.3.1, the F3 option on my Pro Control no longer toggles between "fixed" and "velocity sensitive" encoders.
 
A:
Pro Tools 5.3.1 introduced control of PRE. Pressing F3 on Pro Control switches the encoders to control PRE. To toggle between "fixed" and "velocity sensitive" encoders, hold down OPT(ALT) ALL and press F2.
