Yes, I feel your pain, brother. I'm a gigging muso who flies a couple of times a week and has the luxury of a reasonably capable road crew, as well. I love my TimeFactor and ModFactor but as you've pointed out the power issue negates their usefulness and sonic value. It's just too damned finicky and fraught with danger in a rushed stage changeover scenario. So sadly, they stay at home and are never used live unless the gig is extremely local (rare) and I have the time to set them up myself.
