THREE Cheers for Jørgen ! Sounds like Truly a terrificly USEFUL utility program that you've come up with here, and which will make style OTS assignment & customization MUCH EASIER for Yamaha Tyros & PSR keyboard players. I look forward to checking out "OTS editor" out on my Tyros. Quite an impressive addition to your already comprehensive collection of utilities for Yamaha keyboards. User community support of Yamaha arrangers is truly unsurpassed by any other arranger keyboard brand. Thanks to buddy Tom Griglock for putting the program thru its paces as beta tester as well. - Scott
