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

Hey everyone. I'm a veteran keyboard player but a novice with the 
groovebox-type machines. Can anyone simplify for me the process of recording 
sounds from  my Korg Triton or N364 keyboards into the Xl-7's sequencer? I'm 
sure that it's just a matter of MIDI channels, but I'm frustrated with trying 
to learn it myself (manual is no help in the controlling department).  Once I 
get that right, can I make a song or pattern using a track combination of 
external sounds and internal E-mu presets?

 I know it might take a few minutes to type it, but any help is greatly 
appreciated. Thanks!
