Hallo Forum,

Seit dem Update von Catalina 10.15.4 ist der Audio Export in Dorico 3 fehlerhaft.

Wer kann mir helfen? Bitte um Info, Danke.


Hallo Klaus, could you please post a Diagnostics Report (Help > Create Diagnostics Report)? That creates silently a zip file on your desktop, please attach it here. Thanks

Hello Ulf,

Thank you for the quick response, attached as an appendix to the Diagnostic Report.

Hi Klaus, the logs look quite normal, nothing unusual as far as I can see.
Would you be able to send me one of the project files to ‘u dot stoermer at steinberg dot de’. Full confidentiality guaranteed. That would help greatly, thanks.

Hello Ulf,

attached 2 projects are on the way by e-mail.

A number of apps and plugins have gone weird since 10.15.4 was released. I would submit a report to Apple, too.

A number of us have looked into this today and we don’t believe there is any new problem with exporting audio in 10.15.4. Klaus has also been able to successfully export the audio he needed.
