In the late 1990's or early 2000s I was recording live drummers, and I ran into a program called Drumagog. It was a drum replacer, one of the first.
Drumagog was a lifesaver. The designer made it so that even if an exactly equal drum was sensed, the program would rotate various samples with minute differences. The program had internal samples instead of sending a MIDI output. (Although it might have also had MIDI, I don't remember). The results were a very real sounding drumset.
For instance, I recorded a drummer who was so proud of his DW drumset, but actually it sounded hollow. So I "Drumagoged" the bass and snare with a replacement DW kit from the Drumagog library. Wow this worked great. And my drummer thought his DW drums sounded fantastic. He never knew I replaced his miced up drums.
Drumagog was a new program back then, and it was a one person developer. So it was a little buggy, but the developer was really anxious to resolve issues.
I don't record acoustic drums anymore, but if I did, drum replacement would be my game.
