Hello Marty,
Sorry to be so long in replying to your post. I use
www.psrtutorial.com website.
It is a great website offering styles for almost any keyboard you can mention downloaded direct to your computer or can be purchased on a USB stick. The site also offers invaluable information on many music related subjects/problems. Try it! I think you'll find the site most helpful and very friendly.
The other company I use is Strawberry Music Ltd run by Neil Blake. He has some really interesting midifile book collections available right now. His web address is
www.tyros5.comHave fun!
