SOME of the sounds are pretty good (better.) I primarily use it with Band in a Box, and notice the volumes among patches vary WIDELY. Also the default reverb is off the hook, and if I lower it, I have to choose either a right or left channel, as the center goes quiet. So far, not nearly as consistent as the SD4.

I'll try a new cable for the USB power. My SD4 ONLY worked off USB after awhile. I am getting the main board replaced. My WX7, SurfacePro 3 and Roland Amp ALL run with just batteries. I really don't want to be restricted to AC just for a sound module (no matter HOW good it sounds.)
