Has anyone experienced this issue?
I have some small edits I’ve made to the mix within an instance of Halion Sonic in Dorico, but as soon as I click out of the window to go back to my score, the level edits I have made in the mix tab get set back to their default.
I open Halion and make these edits to the mix tab:
And then click back into the “Play” tab, after which the Halion mix faders snap back to their default level:
I have even saved a Halion preset that surprisingly did save all of the levels and patch data I messed with. When I load it, the custom levels appear. I then click out of the Halion window, and like what’s pictured above, that happens.
Has anyone experienced this before and know if there’s a fix for this? Thanks!
