Taking the cue from Frank and Rikki, I think I am going to order Jos Maas’ OneManBand version 8.0.

I am curious to see how these Yamaha Style Files that I bought would work with OMB.
I downloaded all the Yamaha PSR Style Manager programs by Jorgen Sorensen and Michael Bedesem from:

It seems you can slice and dice, mix and match to your heart’s content with these nifty free tools.

Looks like Jos has added a lot of new features and this is a mature program. He has a new program called Busker that lets you quickly convert printed sheet music to MIDI simply by dragging and dropping matching notes and chords from a list.
