EXS 24 Logic Sampler Users Group

I am interested in using VST instruments as well as the Emagic ES1 
and EXS24 in a live situation.  I am primarily looking to trigger 
them live, and not via sequences, but I don't see any way of 
triggering more than one simultaneously.  Is anyone out there using 
this kind of setup?  Any suggestions?  I am using LAMP.

Thanks, Joe Lindsey
