Emu XL-7 & MP-7 User's Group

hi folks,

i'm not sure i'm worthy to be in this group, cause i haven't bought 
the mp7 yet. i'm planning to...honestly!
i would like to use the mp7 as sequencer for my live set-up. i always 
used atari but went over to pc and i don't trust my pc enough to use 
it live so i need a hardware seq.
my problem is... there doesn't seem to be a way to change songs/set-
up without using a computer... i don't want to bring a pc to the gig 
just because i need to change songs! 
for instance... i'm going to use it on one evening for three 
different projects/bands, needing a slightly different setup 
everytime. does anyone know if this is possible, better still, is 
there someone out there using the mp7 in a comparable way already?
i would be very grateful if someone could give me some advice on 
this...
greetz...
