I have been doing something like it...
I take a genuine stereo mix of the drums and treat it completey seperate from the samples...I mix it down in a way that resembles a genuine overhead pair...kick drum kind of thin...cymbals kind of loud...hat kind of loud snare ...kind of 'distant' toms a little pokey'...
Then I treat it with a little bit of convolution verb for the room effect...
Then I hit it with Nigel...!!
I don;t know that it makes it sound any more 'authentic'..I think that is in the programming myself...but it is fun anyway and it does a little something extra...
P&R,
