Many years ago, Yamaha had the same volume Style to OTS ratio problem, which was easily corrected by just lowering the style volume to about 75, then raising the keyboard's master volume control a bit, which took care of the offset. Can't believe they would allow this to happen again. Someone just blew it, but it can all be corrected with an OS update if it gets to their attention.

Good luck,
