EXS 24 Logic Sampler Users Group

hi wizards. i probably overlooked something. have a hardware 
sequenzer (16midi tracks), from wchich i want to control several 
exs24 samplers/instruments. i keep running into the problem that i 
need to select an audioinstrument in the arrange window to make ONE 
sampler work (which then plays back all midi notes coming in from the 
16 hardware sequenzer tracks.) can it be done: triggering different 
samples (ex. loops, vocals, sounds) on different channels. different 
exs24's of course too, so that i can implement various FX + EQ 
channel settings. i understand that the selection of the audioObject 
in the arrange window is part of the underlying logic of LOGIC, that 
should not be an excuse for exs24 not to work on multiple channels. 
your feedback would be very much appreciated. also controller for 
filter don't work via outside sliders, even if set to the proper 
numners.) - damn i just wanna rock this exs baby live on stage with 
my blasting 909, jomox & virus setup. is that possible. or shall i 
switch to a more dance-oriented product.
peace - superefreaque
