Exactly what I was looking for. Awesome grooves, about 25 "songs" with an amazing set of variation within each "song." I like that I can just use the GM MIDI files with any of my software, I happen to be using this with NI Battery 4 so far. I had the melodic parts for an idea created, went to this collection, searched for about 10 mins to find beats that fit what I had in mind, and it worked perfectly. If they release a follow-up to this beat pack, I'll be the first in line to buy it.
