Hi Tigerfool,
Download this zip file. You will have instant access to 3000 new Styles in the Yamaha Style format (.sty). You can play them to hear what they sound like by renaming the .sty extension to .mid
http://s88002311.onlinehome.us/pogingtwee.zip This contains the entire collection from the PSR350/5450/620/730/740/8000/9000 and some Ketron and Korg Pa80 styles. There is also a MIDI folder that holds the factory demos of the CVP209, DXG500, PSR340/350/550/730/740.
The 50 MIDI piano solos in the CVP209FactoryDisk folder are spectacular.
Enjoy!

P.S. I am going to check out the Yamaha CVP-307 on Christmas Eve. I can hardly wait.
