Separate HPF/LPF for main & monitors please. There are two separate master EQ now, it would be nice to have two separate HPF/LPF.
One for your personal monitor and one for the house. I never use the EQs there but do HPF/LPF. Settling with one is OK, but 2 would be better.
The slope seems to work great where it is so I wouldn't go so far as to ask for an adjustable curve. Maybe 3 different ones if that was easier, but would be very happy with just 2 separate filters for Main & monitor outs.
