I'm running Finale 26 on Windows 10. Previously I posted a question regarding MIDI files not playing on my keyboard. Files seem to upload and seem to "play" as the metronome light blinks for the tempo but there is no sound. I created a test song in Finale 2008, saved as a MIDI file, uploaded onto a thumb drive to the keyboard and the song played just fine. Is there such a thing as a newer software program (Finale 26) using a newer MIDI code/protocol that an older keyboard cannot recognize? Further, is there a way to covert a file created in Finale 26 to Finale 2008? 26 uses .musx but 2008 uses .mus. Additionally, how do I convert a MIDI file created in 26 back to a Finale file in 2008?
