Some backround on how I set up my kits:
I need each drum instrument to be routed to its own output.  So use a 
layer for each drum instrument.  Kick-layer 1, snare=layer 2, ect.  I 
then assign each layer to its own out by using either output 1, 2 or 
3, and panning each layer hard right or left.  Once I add both links 
to a preset, I'm able to send 6 sounds to 6 outputs separately.  This 
limits what I can do to each drum sound, but I have to set it up this 
way for mixing purposes.  Any way...

I am looking for some ideas for drum sounds.  I could use some 
suggestions on filters, LFOs, auxes and anything else that effects 
the sounds.  I could also use some suggestions on routing patchords.  
I use maybe 2 or 3 patches per layer.  The stock presets use all 24 
per layer.  At the same time, the stock kits sound thicker and fuller 
than mine.

I would simply tweak the stock presets, but they're set up to send 
the entire kit to 1 stereo output.

I'm looking for realistic, but aggresive sounding drums.  Any help 
would be appreciated.

Thanks!
