Weird problem this morning that I can’t find a solution to on the forum: I opened a project that uses a microtonal key signature with the tuning of A4 = 440, and now when opening other projects I notice that on headphones Dorico plays back with the tuning ca. 250 cents higher than it should sound (A4 sounds like a B quarter flat) - but if I unplug the headphones and play back over the in-built speakers, it plays in proper tuning again. This happens in all projects now, also after resetting and rebuilding HaLion Sonic SE. The problem actually persists across different sound libraries (Dorico Beep etc).
This is on MBP Catalina 10.15.2 just with the in built speakers and basic apple wired headphones.
I’m guessing it’s something to do with a sample rate mismatch when it automatically switches between outputs, but everything in the preferences is set up for 44.1hz SR, and the tuning to 440, so I’m stumped. Any ideas?
