When I export a MIDI file from the Mac OSX version of Metro SE 6.3 as either a type O or type 1 and try to open it in a MIDI app on my WinXP box, I get an error that says "unknown file type", and another Win app says "Does not contain a MThd. Not a MIDI file!"
How do I export MIDI files that will work on PCs?
Thanks for any help you can give me.
