Haha...I almost posted more information, but thought it would be fun to wait for you to post that

As you know very well now, this was covered in the other thread by AJ who explained it in some detail.
Roberts method is just how Ketron chose to do the styles, there is no reason why you couldn't use pre recorded drums loops from any source and use them with your own skills as a style writer - or even use converted styles and add your audio loops into the drums. This is the method I would have thought third party style houses would have used. I think they are just too lazy to be bothered with it when they can churn out 2 bar midi styles like there is no tomorrow.
Doesn't matter how many times you say Audio drums are dead they are absolutley here to stay just as much as CD's were back in the late 1980s. A large number of people just like you said they wouldn't catch on as you cant record on them

I wonder, do you still use a Sony Walkman with a 90 minute cassete to record your music? :p
