Good Lord.But, it is hard to judge in my case because I have about 40 devices between my two board.
Seems like a good idea. I'm still trying to figure out the most space-saving way to do it. I'm not having enough noise problems to make this a pressing concern atm though..I do plan on having the hub and all controllers not interconnected by an audio jack to be on a completely separate ground loop. May as well isolate those since they are the only devices on my boards that can actually have their grounds isolated from the rest.
A while back someone mentioned a voodoo being used to power multiple SA pedals. I've been avoiding that since I didn't want to go below 100mA/pedal, but if more people have positive experiences I'd probably consider.
One last thing I haven't tried: running my controller off a portable USB charger. Can be done, but I've been lazy
