Hi,
Can someone explain how to use the MultiChannel per Track recording 
method?  I must have read the manual on that section 20 times and 
still have a hard time getting the concept.  I experimented with the 
actual assignment but everytime I switch to a new Channel on the same 
track for new presets, my previous tracks (while playing my current) 
gets overwritten with different presets.  What am I doing wrong?  I 
set track 1 for Multi A with Destination Both and allocate Channels 
A01-A05 for different unique presets and save, and I increase to 
track 2 and try to assign Channels A01-A05 for another unique presets 
the track 1 playing in the backgroud sounds different than what I had 
wanted it.  Obviously this is not how Multichannel per Track 
recording works and I'm very baffled.

Any advice is greatly appreciated
