Tom, if you read this. I can send you some audio and a midi file of a snare track that has me keyswitching between the release trigger rolls and single hits. It just sounds like there's a random layering issue or something. It is pretty random in its occurences, but doubtlessly always occurs within the playback of this song. It sounds like all of a sudden 3 or four more snare players enter the room and join in but they're a few ticks off. I am going to open the patch in Kontakt to see if I can find the problem, but I wanted to let you know.
