So here’s something interesting…
I am working on a large orchestral score, and by default Dorico loads three instances of HALion Sonic SE. Also by default, it plays the notes as you enter or select them. Now, on my Macbook Retina (1.2 GHz CoreM, 8 GB DDR3 RAM, Intel HD Graphics 5300 1536 MB) everything slows down noticeably, and note entry becomes painfully slow.
When I delete the three HALion instances, save the project, restart Dorico and reopen the project, everything behaves much faster, even with note playback still turned on in the preferences. Note entry is still slower than Sibelius—in Dorico I play a bunch of notes on my MIDI keyboard and then have to wait a good number of seconds for the software to catch up—but I love the Dorico workflow, and I am sure that future upgrades will deal with speed issues.
Of course, this turns off all sounds in the software. So, as a workaround, is it possible to add a simple MIDI instrument with crappy sounds—or simply a MIDI piano activated by all the melodic instruments—just to check pitches, &c? In my laptop I only see my MIDI keyboard, which doesn’t have any sounds, so it’s no help, really…
And perhaps it would be great to be able to turn off the playback engine entirely and go back to basics à la 21st Century—take the laptop to the piano and bang out the notes ourselves! Good reduction/transposition practice… and perhaps this would make everything even faster??
In any case, right now when I try to turn off the engine, it turns back on automatically:
Any ideas, comments, suggestions?
