jeronimo, I went to a Community College in Michigan, USA. I didn't learn too much about recording, just about theory, acoustics and electronics. I learned about recording on my own, and from the guy I did my internship with, Glenn Brown. And now because of George Bush, I am a semi-out-of-work AE, who fixes computers on the side.
Yes, Mr. O'Brian did that one with Rick Ruben.

For Drumagog, I'm using Nuendo for most records, although I have used Sonar for some that have a shitload of scoring and other midi stuff. It really is a hell of a lot better than Soundreplacer in a lot of ways, but it doesn't match phase the way SR does. Well, like I said, I'm just mixing a sample with the original hit, and the sample is from the tom itself 90% of the time, so I get some good dynamics from the actual recording, and some good attack, and decent seperation with the mix. I haven't needed to gate my toms but for a few instances. With this mixing, I can get away with only using ONE tom sample (with exceptional attack). I use three samples at three levels usually though. This took a bit of experimenting to get right in the beginning, as to how dry (room) the toms need to be to work, but I found to my suprise that being quite dry gave me the best results. Its pretty different from what you are doing I am thinking, but thats what I do, when I need to do it.
I'll the guy I did my internship with what he does with SR. I don't think he works with drummers as fast as Dave Lombardo on a regular basis, and I think his answer will be something along the lines of only using SR for snare hits, and never at a 100% replacement.
