Midi Counter

[Conor Cook]

Dear All,

I am writing a new email regarding something I spotted in Guy’s example.  When 
I played the Midi file through Frescobaldi, it started counting 3/4 beats as if 
the pickup beat was beat 1.  Is this the normal way Midi files are produced, or 
specifically a Frescobaldi issue, and can it be fixed?

Best,
Conor Cook
