I use a Gmajor also. No problems whatsoever. I use the G7 software editor and an Edirol MIDI->USB adaptor to hook it up to my PC to edit and change patches and make changes. I also have a ground control
midi controller to switch patches.
One thing I don't like about the ground control though is that there's NO owners manual to be found anywhere. I got it off E bay and no reply from
voodoo labs so for now, I can't turn on and off individual effects like I want to, just changing through patch banks.
The quality of the effects though are amazing. Crystal clear, no tone coloration.
