About 5 seconds after I open a Trumpet and Organ Dorico 6 project, a window appears called Halion Sonic - find missing samples. Behind that window, another appears called Halion Sonic. I have tried everything I know (previous Finale user) but so far, the trumpet sound is missing. In the left lower corner it says: 464 missing files. I am at a loss.
Please do from Dorico’s menu Help > Create Diagnostic Report and post here the corresponding zip file.
From that I can give further advice.
Thanks
