Unable to launch Dorico 6 as Audio Engine not starting.

Looking for clues to get me started. Mac OSX 15.7 Thunderbolt Lynx Aurora Interface.

Help?

Hi @Dave , try (after force quitting Dorico, if stuck) to force quitting the VSTAudioEngine process from the Activity Monitor. Then, when it is gone, launch Dorico.

(But probably someone of the Team will answer deeply, after they evaluate your diagnostics)

Thanks for response Christian

Tried that sequence of events but no joy.

Dorico doesn’t seem to identify that the VSTAudioEngine is there. The Activity monitor shows it OK but very low %CPU and Recent hangs shows 0. Just as Dorico invokes it but then doesn’t use it? Other programs like Cubase seem OK.

Thanks

I assume you have tried rebooting the computer?

Shows VSTAudioEngine?
Dorico will not launch if VSTAudioEngine is running.

What I am seeing is that Dorico is launching the VSTAudioEngine on loading but then not using.
If its not meant to load what is the Audio engine Dorico is seeking?

Re Dorico issue

Have now solved but not clear how? It appears to be a cross linking or corruption in the User Library Preferences folder on my Mac Studio.

Had Just recently installed Cubase 15 and that too started giving boot up issues.

So I renamed the Cubase 15 folder to Old and let the next boot rebuild the entire folder.

That appears to have solved 3 recent issues.

1: Cubase 15 was reporting I didn’t have a Retrologue licence (despite that being bundled as part of pro)

2: Cubase booted OK with no hangs

3: Dorico 6 Elements opened OK.

I was watching the preferences folder rebuild during the Cubase boot in finder and the same window showed the Dorico 6 preferences so I could see xml files being built in Dorico which were clearly not being placed where they should at first boot.

Theres is a folder called Dorico 6 AudioEngine T3 Cache (arm64) which was then added. This folder seems to show files relating to plugin scanner and cache.

This could explain why all problems solved as there was some sort of file corruption on the related XML files in the Cubase 15 install.

Don’t fully understand what’s going on but the logic hangs together re the issue.

So need to examine the old Cubase 15 XML file creations some of which may have been migrated from my Cubase 14 Preferences.

So looks a Cubase 15 install file corruption issue for me.

Good to solve 3 issues at once lol

Thanks for initial pointer gave me a clue to look around.

Cheers

I think what happened to you was a hang during the plug-in scanning. The audio engine launches another process for that and waits for that to finish. That’s why the audio engine appears to do nothing, well, it is not doing anything except waiting for the scanner process to finish which is hanging. Then after a reboot or so, it overcame that hanging in one of the plug-ins and now everything is fine.

But let me know should the trouble come back again.

Thanks for response.

It was odd as I installed Cubase 15 Pro and it was all working OK except for a failed Retrologue licence error which I have raised with Steinberg Support. The following day I tested Dorico and found the loading problem. So it must be sequence of events in Cubase 15 install importing or creating a corrupted XML file. That file must be shared by other programs liked Dorico so as you say Plugin related. After the hitting the Dorico problem I retested Cubase load and it hung at trying to load audio drivers so still no real pointer to plugins. But I started to join some dots. Still hunting for corrupted file.
