Addictive Drums are an amazing sample library/plug-in that is so realistic, it introduces the complexity of mic'ing a real drums set, specifically mic bleed. The sweet spot that I'm looking for is a the hihat hit sound along with the combination of the hat mic, the OH mics, the room mic, the bleed into snare and tom mics and it is velocity-based.
The sweet spot will be the basis of velocity with a swing anywhere from, let's say -10 to +10. I'm not saying that I'm going to use the same velocity throughout but if you use AD, you will agree that a closed hat at 60 sounds drastically different at 80 as it does at 100. If I set the middle at 80, my velocity range would be 70 to 90, assuming no accents like TICK tick tick tick TICK tick TICK tick and it sounds very natural.
I know I'm not doomed to failure because what I'm getting now sounds extremely realistic, but, at times, I become a little OC when it comes to detail because sometimes I get so side-tracked with a specific detail that it prevents me from progressing on a piece of music that I'm working on. I focus on the technical instead of the creative and it's hard for me to break out of that.
It took me almost a year to finally dial-in a crunch rhythm guitar sound that I liked/was after! (The IK Multimedia ARC system helped move that along at much faster rate since my mons weren't accurately letting me hear what was going on (that's another story))
Anyways, there's a good reason for what I'm doing that has more than one good purpose; let's say you have a sample that has multiple articulation layers that are velocity-based, the method that I'm using would be able to pinpoint at what specific velocity the articulations change and what specific velocity they change again.
