I just talked to PG and the chat folks did not have information on this and I suspect maybe nobody does outside of the engineers. I wonder if the drummers were playing to a click track for their performances or were playing to their own sense of time. Also I wonder whether the engineers quantized the recordings prior to their making them available to us BB users. I have been listening to some of these recordings and they seem quite life-like to me rather than sample based programs that use real audio samples but then assemble them in a MIDI rigid time frame. There may be no answer to this outside of closely guarded techniques, but I am curious. Anybody know anything about this or is it a black box?!?! smile
