I agree, when Boss innovated this, like 6-7 years ago, it was a great thing I wish the others had done. I didn't know Fractal had adopted it. It is much more elegant than scenes and having to build these huge monolithic patches that try to do everything.
The other way to solve this is to use supplemental pedals. There are so many good, affordable solutions. I just added an IR-X to act as a "global block" preamp. I'm headed in that direction. If I need a global anything, I am more inclined to just buy an individual pedal and add it to my setup.
If I was going to upgrade to a new MFX flagship processor, this is one of the things I would look for.
Its crazy that new modelers come out like TMP and QC and they get disqualified from consideration for missing some basic things. Or that Line6 hasn't adopted it and is all in with scenes.
