Note: I was actually able to partially solve this problem by following this post from 2016 from Daniel, but I’m hoping there is an easier way then manually duplicating each of my existing files. Here’s the post: https://www.steinberg.net/forums/viewtopic.php?t=103824
I just updated to Dorico 3 and about 90% of the time, I run into problems working with my older projects created in Dorico 2.2.1. New projects do not seem to be affected as much, but I have had the issue with new ones a few times, too. I am running macOS Catalina 10.15 on a mid-2012 MacBook pro. I’m running Dorico 126.96.36.1991 (October 7, 2019).
First, I do not get any sound from my VST instruments. When I go to the Play mode and click on the “e” edit symbol, but only the blue light turns on. The instrument doesn’t pop up. This occurs for both HALion and for third party instruments like Kontakt. They instruments are definitely activated. I cannot hit play to start playback because the button itself is greyed out. This generally occurs for only with my old projects from 2.2.1. On the occasion that they do work, I am able to load instances of HALion, Kontakt, etc. with no trouble.
I tried resetting the playback template and tried opening the playback options…no luck there. When I tried the latter, I’d get an “error connecting to the audio engine.”
When I’m having this issue, Dorico 3 also freezes completely when I try to save these files OR close the program, requiring me to force quit.
Anyone have any ideas or suggestions on how to make this work?
Update: As I mentioned up front, following the duplicate file/zip/delete VST info/convert back to .dorico process DID work for me and did preserve the instances of the VST instruments I used. I did have to manually reload each individual sound within those instruments, but that didn’t take too long. I’m posting this hoping that one of the developers or experts might have any additional advice. Perhaps it’s a Catalina issue. Before updating, I checked that the third party VSTs I use are compatible with Catalina, but even without using them (sticking with HALion only), I was still running into issues.
