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

Hi,

Just picked up a new XL-7, I'm looking at the Korg MicroKontrol, with 
its drum pads and 8 knobs and 8 sliders.  If I connect this keyboard 
to the XL-7 will I be able to patch its knobs/sliders to the XL-7's 
parameters such as the modulation matrix (patchcords), effects 
settings, LFOs, EG's, etc?  I'm sure I will but will it be an 
intuitive and streamlined process?

Also, I'm looking for a studio sampler like the E-mu Ultra series or 
the A3000, A4000, or A5000 from Yamaha.  I like the fact Yamahas are 
filled with many effects, and from what I've read, are easier to 
use.  I don't need to burn ROMS, since this setup will be used at 
home.  I want a sampler that works like Recycle, and allows twisted 
sound manipulation and synth capabilites for abstract and IDM music.  
Money is an issue, so used is the word here. I guess reliablity too.

What I'm looking for is a powerful system consisting of 3 pieces, the 
XL-7 for its sequencer and ROM sounds, a MIDI keyboard with knobs 
(for more control), and a studio sampler with effects.  Maybe an FX 
box if the sampler doesn't have many.  I looked at the RS7000 for a 
while but it looks limiting, and I've told I can get more power out 
of seperate components.  My concern is weither using all 3 devices 
together will be smooth and relatively easy.

Thanks in advance for any advice,
Mike
