Hey All...
For the past few months, two friends and myself have been working towards a live electronic show... Picture this:
Me, with a guitar strapped to me, a mic in front of me, my MPC in front of me, to my left, my MIDI controller and rack - with E6400 Ultra, Emu Xtreme Lead-1, tc electronic M300 x 2.
Another mate, with my mackie sr24-4 mixer, and his own mic.
Another mate, with an original Fender Rhodes Stage model, and his Roland Rd-700 above that, and a sax, and melodica (and obviously a mic for the latter 2).

So, what I need to do, is switch between an entire bank on my emu quickly... I have all the channel volumes, pans, outputs all set for each song... at the moment, i'm loading up each song from my ext. zip 250 drive, which takes about 30-40 seconds for each load... each song is taking up about 25-30mb of my sample memory...

is there anyway, i can load up say, 4 songs in my emu, and switch between an entire bank on the fly?

thanks yo.

I believe that channel volume, pans and outputs are saved in the bank, right? I don't think there is a way to do what you want without going eos 4.7, but I'm not really accustomed to the ultra's, so you better await somebody elses answer.

thanks ole - is there a way that you know of in 4.7?
i have installed 4.7 once before, and ran into many problems...
