Because the styles are generic .sty style files, they should work on nearly any keyboard that can read .sty styles. However, some of the folks with psr-740 yamaha keyboards had to remove the One Touch Settings (OTS) in order to make them work and prevent keyboard lock-up. I've been told they worked well with both the Tyros and 9000 pro with no modifications. The best way to tell is download disks 1 through 4 from www.psrtutorial.com and give them a try. Some of those files were from my archives which also included Technics.

Good Luck,

Gary
