Halion Symphonic orchestra missing from VST lineup

Since updating I seem to have lost my Halion Symphonic Orchestra Sounds.

See attachment

Are you saying you’ve lost the sounds if you select Symphonic Orchestra? Because the subject line seems to indicate that you’ve lost the selection from the lineup, yet it’s right there in the screen shot you posted.

So if you select it, it doesn’t produce any sounds - is that what you’re saying?

What happens if you select “Apply default playback template” from the Play menu?

Try choosing Play > Apply Default Playback Template, which should allow Dorico to load sounds again in that project.

I would recommend using HALion Sonic SE rather than HSO. It will load all the HSO samples, plus others besides.

Thank you Daniel and others for your knowledge and time.
