Missing Instruments in Noteperformer 3 Mixer

I have a score with 23 instruments which gives me two instances of NP. I then added another 4 for solo violin, viola, cello, and bass. Unfortunately they don’t show up in the appropriate NP mixer. I added them as players to my score in the normal way - NP is set as default ex. map and NP is assigned properly in the end point grid. I’ve tried the reset in NP and everything else I can think of but no joy.

Any help appreciate.


Please go into play mode, play menu and playback template > Noteperformer. This way, Dorico forces NP to restart and load all the instruments. Any changes you have made manually will be list, but all the players will receive their instruments.
