I have been backing off the EQ and compressor settings, but not turning them off altogether. TBH, a lot of the styles need a considerable rework to get right if you do that... The EQ and comp tends to flatten out some of their inconsistency.
About the one thing I do is jack up the bass and drums to nearly flat out... This is a bit faster than turning all the OTHER Parts down, and also has the benefit of balancing the default RH voice volumes, which are, IMO, too loud. OTOH, I don't think I've heard more than a handful of user demos on anything, where I didn't feel the RH was too strong, so your mileage may vary! I've played in real bands too long to feel comfortable hearing my parts front and center!
Take a good look at that BK-9 editor... it might be time to get a new iPad!
