I've spent hours now trying to mess with the different snare sounds 
and layering, and none of them sound real enough. I want that tangy 
after sound produced by a steel snare, but I also want that tough, 
loud snare/head, just like a real steel snare drum. What are some of 
your snare set-ups? Layers, volumes, tunning, etc. It would be 
helpful in me finding the sound that is just right

P.S. Right now I am using Layer one at a volume of 127, a tunning of 
0, a reverb of 55, and a decay of -10 (Deep & Dry) and Layer 2 at a 
volume of 50 and a tunning of -1 (Bingy*...not sure on the spelling) 
and it just doesn't seem to have a full enough sound.
