Look, I have not used the FM9 live yet. So maybe global eq will work. Maybe preset and scene levelling is where I need to develop my skills.
But my prior experience involves running a fuzz, a distortion, and an overdrive in series into an amp. So the volume and EQ contour of the low end changes as I switch pedals and combinations. Each pedal has its own EQ, each has its own small boost. Sometimes I would get to a venue, and find the gainstaging and EQ profile of one pedal was off compared with my practice space and off compared to the others. With a traditional pedalboard, no problem. I adjust the pedal. But if I want to take full advantage of the preset per song model, I couldn’t make those changes at the venue. I don’t see how global eq solves that problem.
I’m not wedded to global blocks, but I am still trying to figure out alternatives to solve this specific problem, maybe global controls could work. But I’m also not sure how I would implement that yet. I thought maybe mapping scene volumes but that’s not an option. I’m still learning the ins and outs of the FM9.
