I have a 12 staff, five flows 17 minute piece with NotePerformer playback. Sometimes Dorico slows down and playback starts to hack / jump. I have to save/quit and restart.
Did you try increasing the buffer size? (Device setup) It might help⌠(although I have a Mac client with the same symptoms and it didnât help for him )
For comparison, I have Dorico on 18% and VST on 74% while playing back a piece with over 20 Players and 30 Flows using NotePerformer and other VSTs on a 6-core i5 Mini (2018).
My buffer size is 256 samples. (Edit > Device Setup > Device Control Panel). Other than that, try re-applying the Playback template. Is there anything non-standard about your audio setup?
What is strange in my eyes, that Dorico itself is using up so much cpu power compared to the audio engine. The figures should be the other way round. Do you have condensing switched on?
The only things Iâve modified is a couple of playback issues:
Changed the length of âdefault noteâ value from 85 to 99% length, both in Playback options and in the expression map of NotePerformer (Playback overrides). I know NotePerformer recommends 85% but it sounds very short on most notes.
Thanks for the data, but when it comes to performance the log data does not show very much. Maybe we could have a remote screen sharing session at some stage.
It is not an official and supported solution, but if you donât use video in Dorico, you could completely remove the videoengine.bundle from the Dorico application, since it is known that this engine causes a lot of cpu load, even if your project contains no video at all. See this post from Ulf:
In my case it makes a big difference, the first screenshot is from playing back a project with the unmodified Dorico application and the second screenshot playing back the same project but with removed videoenginge.bundle:
