I have a ProFX6 v3, have question about USB and faders on channels 1 and 2.
Checking out with headphones, channels 1 and 2 mix like they should, faders (knobs) work fine.
Then I plug in the USB for Mac I/O.
When I select "TO PHONES" to engage computer monitoring, it defeats the settings of the faders on 1 and 2. The channels work, but just let the sound pass through; faders do nothing. Gain controls work on both channels though.
What am I missing here? Or is this just how it works?
