IIRC, an earlier implementation of MIDI extraction in SONAR before Audiosnap appeared in S6 had configurable detection parameters that worked like a gate. It would be nice to have this integrated into Audiosnap to avoid having to destructively process the audio. I suspect they deliberately left it out in an attempt to simplify Audiosnap; many users were dumbfounded by its complexity as it is.    Flexibility is the natural enemy of simplicity. 

I wasn't smart enough to figure out the gating thing, so I manually moved/checked the marker for every kick and snare hit for 20 songs (about 90 minutes of music). Took freaking forever. The end result does sound really good. If I was going for total replacement, it wouldn't have been as big an issue, but because I wanted to blend the sample and the original audio, they had to line up perfectly. The default markers caused bad flamming.
 
The other thing is that the snare track had lots of light hits (intentional) that would have been gated out as the bleed from the first rack tom had similar volume. The gate trick would have been fine for the kick drum track. Bottom Line: spend more time getting the drum sound right before recording, don't fix it in the mix :-)
 
FWIW, you can hear the first of our tracks on Reverb Nation. I'm mixing our second song (a hard rocker) this weekend...

I just spent the day doing the same thing as you garry, what a pain...
