This has been a very informative post. It’s really the first time I’ve dabbled with registrations to any serious degree. Thanks to all for sharing your setups.

John...The playlists are available at the Yamaha website. They have one specifically created for the SX900. You have to download the zip file and extract the files to a usb drive. You can then load them into the SX900. Sorry if I sound ignorant...but I’m still learning this keyboard myself. If anyone has other ideas to simplify the playlist loading...Please share.

I didn’t download the Genos playlist for fear of compatibility issues. If there is no problem in doing so please share. If the playlists are the same...probably not necessary to download.
Thanks,
Mitch
