heres my thoughts after really using trigger in the trenches... Just used it on an One 12 track and another Album and b sides (16 songs!!) worth of material so i REALLY got into it....
Im using several instances of trigger to trigger a blend I made of slate snares, the room mics, and my own samples, 3 or 4 Instances per kick/snare. On snare its 99.99% flawless... SOO good in keeping dynamics. However on buildups (and we're talking INSANELY quiet to full bore here) It doesn't quite catch all the hits even with all the automation, input boosting in the world... but thats okay; I Guess..... All the samples from separate instances lined up wonderfully.
Kicks however seem to be a bit less smooth. There were several instances of Trigger 'doing a drumagog' and having the sample just plain out, not phase aligned, not sample aligned; just way way out. This was more prevelant on fast double kick sections. and also, even with the same settings, the different instances of trigger were occasionally out with each other, but the one that was out most often, was not theone with samples I had made myself, but the one with slate samples.... odd.
So in general? pretty fucking awesome. Instrument maker is easy as hell. But i think just to ensure not having to go through and check every sample is lined up, I'm going to be triggering Trigger Via Midi Using Massey Dtm, it just works for me, and means that i know that every hit will work not matter how many instances i use, and i have more control over the velocity of hits when and where i want it. In fact on the really quiet sections, i actually had to draw in the midi and send to trigger.
But on the whole, I'm going to say, AWESOME software, best drum replacer i've ever used, and I'm sure in future it'll get better as it's updated....
but i'll still be triggering it with midi.
