To reduce load time, i made a template document with one piano staff, loading the Pianoteq 5.vst by default. That plays fine.
When I add a new player at a later point while editing, let’s say a Tenor Sax, Dorico doesn’t load the sound automatically. I have to do that manually and assign the new staff to the right sound and channel.
But, although everything is assigned correctly, the new player doesn’t play any sound, no matter if I use Halion, Kontakt or other vst.
