Hi,
I am having trouble with Dorico creating new instances of Halion Sonic when I change instrument settings or even copy and paste music from one instrument staff to another. I had originally opted not to install Halion at all because I do not need/want to use it. I ended up installing Halion because I was unable to assign divisi instruments to seperate kontakt channels and for some reason installing Hallion fixed that. I simply can’t work this way because every time I need to change a setting or paste from one instrument I end up having to wait (sometimes a very long time) for Dorico to make yet another instance of Halion.
Is there some way to completely disable Dorico using Halion at all?
You can tell Dorico in it’s Preferences dialog which playback template to use as default. You can choose this to be the Silent template, which does not load any VSTinstrument at all, or you can create your own template which only uses VSTinstruments you want (e.g. Kontakt).
That is surprising, because then something is completely wrong with your configuration or you ran into a bug. Because with the Silent template certainly no HALion instances shall get created. We need to wait what @dspreadbury has to say on your case.
