Sound Dropouts in Dorico with NotePerformer!

Just installed Note Performer 4.3.
Using all latest versions of OS and Dorico

every two minutes, roughly, sound stops but playing goes on, and resumes after two or three bars.

most annoying

anybody with a clue?

It might be worth increasing the buffer size in Edit > Device Setup to see if that helps.

Daniel, you are amazing!
That did it.
Thank you very much!!
all the best
