The Genesys is backwardly compatible with the WK/SK series instruments. Try www.musicmediasoft.com
as another source for sounds and styles. If you do a web search for the General Music WK-8, SK880 or PS2600 you will probably come up with even more.
I am the national product support manager for General Music in the U.S. and I am always happy to help out with questions regarding the Genesys system. Feel free to send inquires to firstname.lastname@example.org. This address comes directly to me and I will answer any questions you may have.
BTW, thanks for purchasing a Genesys. I am sure you will find it to be a versatile and fun instrument to use.
