I've found DR fairly hit and miss.
On loops and pre-processed material it really shines. I was able to drop in a funky loop, overlay a more meaty kick and snare and even add percussion to it using DR. Seamless and incredibly powerful and effective, even more so when you extract the MIDI to use with other drum programs, or even other loops. Triggering a sub loop from a snare hit from another loop is insanely powerful. Kudos, Bakers!
On live drums, it's been less useful for me.
The first song I tried it on already had the drums routed to busses with mastering grade effects on them. I think that had something to do with the fact that none of the generated DR waveform display actually sync'd up with the actual hits of the drums at all. It triggered fine and in time with the song, but if you're watching along, it's quite bizarre and your mind starts to play tricks on you, if you'd actually heard a missed trigger or not because visually it doesn't line up where you expect to hear a hit.
The second song I tried on raw drums with no processing, either on the tracks or in the busses. Much better and in sync this time.
However, for some reason a section of about 8 bars on the kick track was read in as random "drum stuff" rather than kicks like the rest of the track correctly showed, and obviously none of that part triggered correctly. The filter was something that really needed to be played with quite a bit too - the detection is based on the start of the pulse as to where it sets the sample off, and I found that if I set the filter too low, it had too much of a gradual build to the peak and the triggers went off early. Fine tuning that to get a solid attack on the waveform helped a fair bit.
The snare track was less successful. Because there's no sensitivity automation yet, any ghost notes or quiet hits were lost, and any loud bleed from a tom track would trigger as a snare. Not completely unusable, in fact, if you dragged the MIDI out of it, you could save yourself a LOT of work by having most of the work done for you and you could add or clean up the wrong hits in the MIDI track later, but overall not really in the same league as plugins like Drumagog.
But for a verison 1.0 of this utility, it's a fantastic start. I can see myself getting quite a bit of use out of this for any loop based stuff I do especially.
