Hi , thanks for the project data. It looks like you got hit by an old long time bug, that we could not eliminate so far, because we never could reproduce it on our side.
The bug is, that the audio engine data somehow bloats, i.e. over the time the instances of VSTinstruments increases. With the current state the audio engine loads 1 NotePerformer, 2 Kontakt 7 and 83 !!! Kontakt instances (exact version I don’t know).
I will send you back a version of your project where I delete the audio engine data. You then need to just reapply the playback template and you are back to a normal state.
But that does not explain why that bloating is happening.
So you are working already a long time on that project, right? Do you have your computer running for days sometimes and not closing Dorico but only changing projects? Can you give some other hint of what you are doing especially with that project?
Thanks
