A lot of those libraries have pretty good MIDI loops programmed to use the VSTi drums, and they sound quite excellent, so I'm sure this is a very good way to do things. However, the one thing that everybody tends to forget, when making drum loops for styles is... you are going to need an Intro (or up to four, if you are programming the style correctly), and likewise Endings. And most audio loop libraries don't have those, nor most MIDI libraries in fact, plus the drums for the Intro/Ending really ought to follow the music, not the other way 'round..!

But using BFD or the other great drum libraries, at least THERE you can program in your own patterns for the Intros. Audio loops, I'm afraid you are mostly out of luck, unless you do as the Ketron guys did... hire a studio, hire a world class drummer, mike the heck out of the kit and room, then get him to PLAY what you want! I doubt too many of us will be able to afford that!

What makes the Audya so good is also its' weakness, IMO. Once you start to really like live audio drum loops, you are not going to be too happy with beats you create yourself (at least, either unless you ARE a drummer, or are doing hiphop beats and things like that that drummers don't play anyway), rather the same way that most of us prefer the drums in the best MIDI ROM styles (most of them played by great drummers on MIDI kits, anyway) to styles we program ourselves.

At least, if you are trying to sound like a REAL drummer...
