Dorico cannot connect to the audio engine. The application will now quit

Hi @ma77yd07ca1m , yes, it is surprising with the Native bundles there, but they do no harm.
When the audio engine is stuck, please launch the Activity Monitor app and at the top of that window are three icons, one is a circle with 3 dots inside. Please click on that and from the pop-up menu choose Spin Dump. That will take some seconds, then save the output window and send me. Thanks

Thank you, Ulf.

I’ve attached the spindump.

Hi @ma77yd07ca1m , thanks a lot for the spindump.
Now the case is clear, the vstscannermaster is stuck in an endless recursion. Please have a look in the folder
/Library/Audio/Plug-ins/VST3

Inside that folder is an item called VST3 which is actually a symbolic link to the VST3 folder you are currently in. As the vstscannermaster goes through the file tree, that link recurses to always the same VST3 folder, thus the scanner never comes to an end.
Please delete that symbolic link, kill any process with VST in the name and then try again starting Dorico

Yes that worked! Dorico is now launching correctly. Thank you, Ulf!

Hey Ulf,

Thanks for the response. There is nothing in t //Macintosh HD/Library/Application Support/Steinberg/Components folder

I do have a copious amount of plugins; I use a UA interface and have hundreds of other third party ones.

Thanks

Okay, thanks for that @chapman.welch .

How about the directory

/Library/Audio/Plug-ins/VST3

what is all in there? If you could make a file listing or screenshot, that’d be great. Thanks

Thanks, Ulf

Sorry for the multiples but it only lets me embed one file at a time since I’m new…

I can’t make another reply due to my ‘newness’ so I also have several Eventide plugins (TriceraChorus, Blackhole, etc.). These shouldn’t be a problem, but I want to be thorough.

Hi @chapman.welch , thanks very much, that’s enough for now.
And actually the Eventide plugs are a bit suspicious, they happened to be troublemakers quite often recently.
I suggest following:

  • Navigate to /Library/Audio/Plug-ins again rename temporarily the VST3 folder to something else like e.g. _VST3.
  • Start Dorico again, what does happen? Does it launch until the Hub window?
  • If yes, then rename the _VST3 folder again to it’s normal name.
  • Temporarily move the whole Eventide and WaveShell plug-ins out of the folder, e.g. to the Desktop
  • Start Dorico again, what’s happening?

Hey Ulf,

I renamed the VST 3 to _VST 3 like you suggested and Dorico started, but told me some components needed to be downloaded (as expected). Removed both Eventide and nuked WaveShell and Dorico would no longer open.

Diagnostic attached. Thanks, this is the first time I’ve seen Dorico load!

Hey Ulf,

I think I have it figured out. It finally gave me pop-up windows for the VSTs that weren’t authorized. They were from Oeksound (soothe) and Neural DSP. I removed those, and it works now!

Thanks for all the help!

Chapman

Ah, excellent! Great you could find the culprits yourself.

Hey everyone,
I thought I had navigated the same issue by deleting unauthorized plugins (demos that were still there), however now the problem is back. Attached you’ll find my diagnostics report. Dorico crashes roughly 2-3 times a day, especially after exporting audio from the project.

I’m on a Macbook M1 Pro with 32GB Ram. Enough headroom according to the VSL playback engine via Noteperformer (using around 3-4GB at most).

( Since I was on a deadline and worked heavily with Dorico Pro 5 for the last three weeks, I’ll do a deeper analysis post once I find the time. There were some issues that I encountered along the way.)

Thanks in advance,
Kaan

Hi @kaanbulak , when you say Dorico crashes, does it really crash or just becomes unresponsive?
In the diagnostics I can only see one crash file and that is from the audio engine; the crash happened while exporting audio. Depending on what you do, Dorico thereafter sooner or later becomes unresponsive because it tries to talk with a non-existing audio engine.
When Dorico becomes unresponsive, could you please take a spindump via the Activity Monitor app and post here? Thanks

@dspreadbury , since the topic here is about Dorico not even starting up, I think Kaan’s posting should move to a separate thread.
