Composer 3 discrepancy with MuseScore 3 & Yamaha MOX

[Reinhold H.]

The MIDI-1.0 protocol contains the meta event "Key signature" (see page 10 of the MIDI-1.0 spec).

In our software we use the logic

• if the Meta Event "key signature" exits in the MIDI file then the software takes this event to become the key signature
• in case there is no "key signature" MIDI event present, the software does a best guess

The attached MIDI file "come fly pt.mid" contains the MIDI meta event key signature to be F#. This key is used when imported.

I have checked the 6 other major notation programs which we use for interface testing. MuseScore is the only one which goes with B sharp but everyone else chooses F# just like Composer.
