Maybe this isn't the thread for it, but I'd sure like to read about how easy (or not!) it is to create a user audio style. Anybody here done it?

I know the drums would probably be the easiest, so let's stick to that? There are many many fantastic loop libraries of drummers playing real kits, often played by big star drummers. I'd like to know, if I had a few of these libraries, how easy is it to import these loops and create an audio style with them...

Please, although a link to the manual that tells you about this, I'd REALLY like to hear about it from someone that has really TRIED. You never know about the 'gotchas' until you talk to someone that has done it!
