I might be slightly off-topic here, but this is the closest StackExchange site I could find to my topic, so here goes...
I recieved a sibelius file with a choir arrangement from a friend. Now, I want to make some changes, and among them is changing the clef of the tenor part from bass clef to tenor clef (i.e. a regular treble/G clef with 8va noted underneath).
I've found the option "Create Clef (Q)" which lets me change the notation, but for some reason it doesn't honor the 8va and therefore plays everything one octave too high when I try to export the MIDI track.
How do I tell Sibelius to play the part one octave down?
