Pat,
With both pieces of software, you will hear the style play in CMaj7 scale. It does not sound the same as on the keyboard. The keyboard will interpret this scaling so it sounds (plays) correctly when played on the keyboard. This is one of the reasons it is so difficult to make styles from computer based software. If you load a style into a standard sequencer you will hear the same effect. And it's probably why Yamaha does not release Style Creator software for the PC and Mac. The code could be hacked or reverse engineered by some programmer. It is one of Yamaha's secrets that they don't want anyone to know about.
You kind of get used to the sound of things and can make some sense of it even though it sounds a little weird.
Regards,
Joe H
