EXS 24 Logic Sampler Users Group

OK. I've read everything I could find about setting up the EXS to use multiple outputs (for a 
drum kit). Set up the groups, created the aux objects, and basically got it to work.
Two things are holding me back, though:
1. It seems that all my sequences have to be on the track with the actual EXS instrument (I 
can't place the individual drum sequences (i.e. snare, hat, etc.) on the aux tracks. This 
makes it hard to edit the sequences, since they are all piled on top of each other.
2. Looping only seems to work for the first sequence on the track. If I record a 1-bar kick 
sequence, I can loop that, and the loop will play. But if I then record a 1-bar snare 
sequence on top of that and try to loop it, only the kick sequence loops.
Any suggestions? As always, thanks in advance!
