And what is missing from the pa4x
I noticed a few things... it doesn't accept the FC5 multi-pedal.
It doesn't have XLR input.
It doesn't have the rows of programmable sliders, just two knobs.
I'm sure there are more. I've already seen enough that it certainly doesn't tempt me to change from the PA4X, but if I didn't have it, I'd sure be in the market for this one.
