I just now bought Dorico and still have to figure out a couple of things. My biggest problem currently is getting any kind of VST working. I have HALion, of course, and also bought NotePerformer some time ago for my copy of Sibelius.
I read everywhere that in order to get them working, you have to go to Play>Playback Templates, which I did. However, neither NotePerformer nor HALion showed up in the list, and yes, I made sure I installed them.
I run Dorico Pro 3 on a 2015 MacBook Pro running MacOS Mojave.
Thanks a bunch in advance!
