Dorico 4 Blank Mixer, instrument not playing and missing chord names issues


I just upgraded to Dorico 4.0.10, Have had a few issues with the Mixer window being blank when I first access it. It seems to fix itself after a couple of attempts or going to the Play window not the Write window.

Another weird thing was that the left half of slash chords was missing. This is with files that I have imported from Dorico 3.5 which have never behaved in this way.

And lastly, one instrument will not play back. at all It makes a sound if I click on a note in the write window but wont play back. If I look in the window where you can adjust drum maps and playback styles (sorry I don’t know the name) it shows that no instrument is loaded. I am stumped.

I found the announcement about the update to 4.0.20 hoping this would rectify things. However the download fails shortly before being fully downloaded. Again I never had these errors previously.

My System is as follows but it has been running hitch free for at least a year. Any suggestions are most welcome.

Cheers, Tom

Restarted my system. Re-installed Dorico.
The Chord display issue seems to be resolved as has the Mixer not showing any channels but I still have instrument not playing issue. No change, if I click on a note I hear it but there is no playback.
Suggestions please.

Cheers, Tom

I’m glad you were able to make some progress with your issues, Tom.

If you show the Mixer before the project is fully activated for playback (i.e. before the play button on the toolbar becomes enabled and turns green), then it will indeed be blank at that point, because the output channels etc. presented by the VST instruments in use are not yet known.

The font problem you had is a standard font cache issue, and restarting is the remedy.

The problem you’re having with one of your instruments not playing back: this affects just one project, I assume? If so, please try going to Play > Playback Template and try re-applying the default playback template, HSSE+HSO (Pro), and see if that fixes things. If not, please attach the project here, and let us know which instrument doesn’t sound for you.

Thanks Daniel,
I am pretty sure that I didn’t activate the Mixer before the instruments were loaded as I had been working on the score and then decided to listen back and balance the instruments. This has never happened before and seems like a new phenomenon in Dorico 4. I will keep monitoring and see if it happens again. I am aware of the green status of the payback button.

I will try your suggestion re the Playback template and let you know. And, yes you are correct that it is only one project that is affected. However at this stage I have only opened about 5 projects.

It worked! Many thanks!
