JEON_JONGIN The very bottom line of the entire sheet only sound 'Acoustic Piano' when there are more than 11 instruments (I was composing an orchestral music) - I checked the parts setup and it was in Contrabass (the instrument I intended to sound). How can I fix the problem? How can I make fermata work? Is it impossible for the program to play the fermata longer? What does '12keys Transcriber' exactly do to the program? For me, it just opens a file and shows it in synthesia mode. It does nothing..
