The company in Germany, Peter Schips is working for, is called CD-Soft ( http://www.cd-soft.de ). The samples you can purchase there for the PSR9000 (and also for the PSR8000) are the best you can get for your PSR. I've compared what Yamaha is offering and what you can order from CD-Soft. I would never change my CD-Soft disc's against original Yamaha discs!! Try out the demos you can download for free.
