Main LR: Low-cut & independent channel volume control (or pan)

Particularly for wonky venues, quick set-ups and on the fly adjustments, I would definitely benefit from having some amount of control over the volume coming from the two channels L and R. I guess this could be solved with a simple panning control of Main LR.

(When running with GEQ) there’s no low-cut which I think would be super useful on the mains. Or, would people simply put a gradient on the graphic? Perhaps that is the solution already.

For some general low cut I would use the parametric EQ with a band opened up wide to make a shelf filter and cut that at the desired frequency.

The low and high EQs can be switched between hi/lo cut, bell, and shelf.
