Installed this 'new' free product that was announced with the new GENOS 2.
Surprise ******* Worked it perfectly on Clavinova CVP-809.
I only ran into 2 small issues.
Could not audition or transfer the new style directly via USB cable. Had to use a thumb drive.
Also, in order to assure the style voices match 'perfectly' with your specific product (GENOS, PSR-SX900, Tyros?) Yamaha suggests you load a product-specific Voice List. I could not locate this file anywhere on the Yamaha site.
Download it from the Genos 2 site. It works on both Mac and Windows.
