Korg M 50 Sequence midi file question

[scat2me]

I have 400 sequences ( midi files) I used on my N264. I transferred them to an SD card but they will not play correctly on the M50. Is there any software I can install on my computer ( windows) that will allow me to edit the tracks and make sure they are all General Midi? Something simple. Any help is greatly appreciated.

I had this problem when I first got my M50. I had to change the pitch on the drum kit in the M50 to +12 ,I think it was, so they would work correctly was all.
