Trouble with that, Bill, is it still only plays the ONE sequence, and doesn't follow your chord input, or switch in and out of fills and Intro/Endings. Getting the basic pattern is not so tough, but designing styles that flow smoothly through the fills and other segments, and seem natural progressions through the Variations, and also provide just the right amount of variety between the maj/min/7th/dim variants is MUCH harder to tell from playing the one chord pattern you just created...
Just getting the chord parts' ranges right, so they don't jump around too much requires the style engine to play the part in the first place... Then listening to any glitches as you change mid beat from major to minor, etc. means a trip to the arranger...
It would speed things up and make decisions about things like this much easier if the computer actually PLAYED the style...
