Al,
the answer could be that -like you wrote- it's much easier to do the same thing with programs like BIAB, and then import the result as a style into the keyboard of your choice.
My experience is that the best styles are those converted from song-specific midifiles or modelled after popular songs, so the bottom line to me is that all I really need are great midifiles and a program like Styleworks 2000, to convert them into styles; the whole process takes less than fifteen minutes per style.
Speaking of song-specific styles, did anyone notice that the Tyros Afrocuban style is "inspired" by the song "At the Mambo Inn", as recorded by George Benson and McCoy Tyner in the album "Tenderly"? Intro 3 is actually a carbon copy of the original; I wonder if Yamaha paid any royalties...
