Anybody experiencing the same? Starting from VCV 2.0.3, the VST seems not to be working in both Ableton Live and Bitwig Studio Using VCV 2.0.4, Bitwig Studio 4.1.2 on macOS silicon shows this error message for both VCV VSTs: com.bitwig.flt.library.metadata.reader.exception.CouldNotReadMetadataExce…

@steve , I have done the test you suggested of deleting and re-downloading all VCV plugins. The, restarted Bitwig, re-scanned the VCV VSTs and… VCV 2.0.4 is back working in Bitwig 4.1.2! However, it still feels like a bit of magic. Why would bad VCV plugins make the VST fail loading? G.

[image] VCV Rack 2, Ableton, and Core Audio VCV Rack Yes - It was only in 2.0.3 that access to Core Audio from within the VST was added - so if your issue relates to core audio in the VST, it would not have happened before 2.0.3. And then (I think) in 2.0.3b, separate Rack…

One thing that you might try is to launch Live, turn off the audio engine, and then quite Live. Now restart Live. It should restart with the audio engine still disabled. Let the plugin scanning complete before you start the engine. My Live was not crashing but hanging. I’ll be curious to see wha…

Thanks @Jens.Peter.Nielsen I wrote to support already. I’ve posted on the forum, too, because the experience of others could have contributed to understanding the root cause. Besides, I hoped I could find a solution during the holidays, I am not sure there’s anybody there working these days. @Yeage…

Rack VST 2.0.4 is working fine here in both Live and Bitwig 4.1.2. I’m on Mac Catalina 10.15.7 It sounds to me like the problem could be related to either Audio or old modules Do you have an Audio Interface? if so which one? You can get the Rack VST plugins to be enabled again in Live by just mov…

@Yeager do you confirm that you can actually use VCV Rack Pro 2.0.4 as a VST in Bitwig 4.1.2 in macOS, that is also my preferred DAW? If so, the main differences between us are the macOS version (you Catalina, I Monterey) and CPU (you Intel, I M1). If we go back to the text of the error messages, t…

[image] giacecco: Why would bad VCV plugins make the VST fail loading I think it probably has something to do with the way plugins load fonts. It needs to be done differently in the VST version otherwise crashes can occur, even on scan. It took some developers a while to get this figured out …

I’m all of a sudden getting crashes in bitwig as well. It’s odd because it seemed like one day it was working fine and now it doesn’t. I can see and load the vst but opening the UI crashes the plugin most of the time. I’ve tried deleting and re-downloading all plugins.

Mmmh ok, however I am quite sure that all plugin were already up to date, by using VCV stand-alone. I believe that the mystery is still unsolved :face_with_raised_eyebrow:

Were you using the Rack 2 beta at any stage? or perhaps had some beta plugin that you deleted? If you used any version of the pre-release beta then VCV said it was important to delete your entire Rack2 user folder before installing the release version.
