Bill,

I've had some Korg Styles converted for Yamaha, and they were really good...they were mostly programmed over 8 bars, which gave them a nice variable quality.

These were from the older I-series, so I suspect they are even better on the newer PA series.

Where Yamaha shines is the sheer volume of great styles available, especially song specific ones, and with today's instruments having such immediate access to hundreds (or thousands) of styles via HD or USB Flashdrives, makes having generic styles suited for many tunes, less important.

I've used Korg styles as donors for making my Frankenstyles as the parts are so variable.
