routing? mixers?

[DialaThos@aol.com]

Hi all,

I'm running a fairly complicated signal path and now trying to integrate a 
Repeater into it.  It's a Chapman Stick rig complete with a bass signal, 
stereo guitar signals and stereo guitar-synth signals all happening at 
once.  
Ideally I'd like a routing setup where I could be playing all 5 channels 
at 
once.. but only looping any given "instrument."   Barring that, I'd settle 
for just having everything go into the Repeater cleanly.

I guess what's really needed here is a good line mixer (preferably rack 
mounted).  The only two I'm aware of right now is the MV800 by Yamaha and 
one 
by Rane called the "(something) 82"  Anybody know of any others or have 
any 
clever routing tips?   I'd love some sort of volume pedal setup to 
determine 
what's going into the Repeater.  

Thanks!
