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

i do not have a xl7, but i am thinking about purchasing  one.  my local music 
store doesnt have one for me to play with, or anyone to answer my questios.   
so i figured why not talk to people who actualy use it.  i will be both performing 
live with it, and in a studio enviroment as well.  it looks great for in the studio, 
but is it a good live tool as well(i love ribbon controllers).?  i am also looking 
for something to control all of my other instuments as well.  i would like to be 
able to have a master sequencer, that tell all my other slave sequencers when 
to play.  i would also like to be albe to trigger additional drum boxes and 
keyboard.  can the xl-7 do it?  and how are the waveforms?  the expansion 
roms?  i do electro and techno.  i've never owned an emu product before, so i 
dont know how good there sound engines are.  is the sampler easy to use?

i know that was alot of questions, but i just cant find the info i want on this box.  
thanx!
