Hello,
If you mean the MIDI FILES with songs which are already played, it is possible to play them at all brands. If the format is changed, you can do nothing. There is a program which is "EMC". It is capable to convert the styles and midi files into other formats. I don't hav it. It will be dificult to do that without the experience.

The new X4 expander reads both formats.
A tip maybe.
Good luck
