Buy a PSR 2100??? Just kidding Kevin! That would be one solution of course.

Michael Bedesem from SVPWorld.com has made a software utility program that addresses that problem if I'm correct in my assumption. I know he has one that changes a two variation Style into a 4 variation Style. I think he might also have a program that changes a 4 variation Style into a 2 variation Style. If Michael doesn't I am pretty sure that there is a program out there on the internet that does.

Uh, I just found it I think. It is called Style Fix. And it is one of Michael Bedesem's programs. The version is 1.1.9 Here is the URL Link: http://www.svpworld.com/util_stylefix.htm

Hope this works for you. PS: I am not sure if you will have to "remove" the OTS or not before the Style[s] will play on your PSR 550. If it is a must to remove the OTS before the Style[s] will work I am stumped and don't know of a program that would do this. Maybe someone else on the Forum can be of assistance regarding that possible dilemma and provide a solution if need be. In fact, maybe Michael's program addresses that issue. If the OTS doesn't have to be removed to play the Style[s] then great. In that case, Style Fix will be all you need either way.

Best regards,
Mike
