Converting to MIDI from PR54M

We have a query from a Member who is NOT a keyboard player but has been tasked to convert songs from PR54M owned by the church so that they can be played on a Yamaha keyboard.

Hopefully she will post additional details here but all ideas and advice will be gratefully received because I am also looking to find out the best way to export MIDI files from my KN7000 in the most compatible version possible.
