The Sibelius Forum

I am relatively new to Sibelius and Noteperformer 3. I am inputting the orchestral score of the Mendelssohn Piano Concerto No 2 in Sibelius 2018.1 for playback with Noteperformer 3 (I will play the piano part along with the orchestral recording generated by Noteperformer).

In the original score, the two flutes start out playing in unison. As far as Noteperformer 3 is concerned, is there any difference in playback if it is notated with double whole notes and double-stem half and quarter notes (see screenshot from the original score) vs single whole notes and single-stem half and quarter notes with no particular indication that the two flutes are playing in unison?
If the answer happens to be "yes," i.e., Noteperformer would effectively be playing one flute instead of two flutes, then perhaps someone with more experienced than I can tell me the quickest and easiest way to notate the unisons in Sibelius.

Thank you.

If you use ~C104,2 that will make NP use 2 flutes
If you use ~C104,0 it will just use one flute until it hits the divisi. if you want better realism then use the C104 command.
