I am using Dorico on a very large project with video (just audio really, but as a video file). It’s about 620 measures and probably close to 70 staves with the piano reduction and my drafts. The program slows down to a halt on almost any operation - and especially playback related operations. Saving can take over a minute and sometimes simple things like adding an articulation can take a minute or more.
I’ve read all the suggestions I could find regarding speeding it up - including using Galley mode, audio buffer size, not loading many layouts, frame settings, not showing attachment lines - but it does not seem to help in the long run. Perhaps the file structure is faulty (it was imported originally from another program, but most of the players were added in Dorico).
I am on a MacBook Pro, 15-inch 2019 (connected to a 2010 Thundebolt Apple 27 inch monitor), 2.6GHz Intel Core i7, 32 GB 2400 MHz DDR4, Mojave, and using NotePerformer
Any suggestions would be much appreciated.
