Thanks for the interest Gerry, I do have a sample of what happend when I imported the MIDI file from SmartScoreX-I was pleasantly surprised when I plated this MIDI file that the first 8 bars had the correct MIDI messages-the rest of the piece is badly damaged in the sound as well as the picture,it's here:

That Link may not get parsed and you may have to type it in the browser,sorry.
What I would expect to find in the score editor is the original in editable version, sorry that sample does not contain the scanned version, but it is 99.99% the same, just 3 16th rests and one misread clef change from tenor to bass. If I was being paid by someone to do this I would just change the length of all notes using transform, but transform doesn't work in the score so I would pray that it worked in the midi editor and double the length of all notes, every bar would have to become two bars and I don't know if transform can do something so simple.
I want to say thanks to the great Apple Team for allowing such heresy on their forum, and sending me notices of replies,really well done people!
