For several versions now, including the latest (7.3.3388), VEPRO 7 no longer scans VST3 plugins correctly.
After a few failed validations, the software starts to loop over a single plugin (screenshots).
Worse still: VEPRO7 blocks on VSL Pro plugins!
The only solution is to isolate the offending plugin and start the scan all over again (reset and rescan all). Except that this already takes at least a day and there's more to come!
I've tried just about every method described on this forum: deleting the caches, isolating all the VST3s (in this case, it works but if you put them back in, some of them block the software).
The VEPRO 7 workflow has become impossible, and I think it's time for VSL to react.

Thank you for the link, but I've already done the tips listed there.
When I delete the cache files, they are not recreated.
When the scan plugin loops, it generates these empty folders in the "sentry-db" folder ad infinitum (screenshot)
When I delete them, it doesn't change the problem.

The only way is to put ALL the VST3 plugins in an "off" folder but then I can't use them in my DAW, it's not an option.

It's crazy that it's not even possible to prevent VEPRo7 from scanning and/or using VST3s.

Unfortunatly, no. I rolled back to version 7.2.1526. It's the only way tu use VSL pro suite plugins. Crazy ! VEPRO7 is not ready for VST3 :-(

Andreas posted the wrong (old) path in the thread you are referring to (I corrected it).

~Users/*YOURUSERNAME*/Library/Caches/VSL/Vienna Ensemble Pro

Please give it another try and let us know!

Best,

Thanks for your reply, Paul. But it still doesn't work.
1. I move all the VST3 plugins from the "VST3" folder to a "VST3 off" folder.
2. I completely delete the cache folder included in "~Users/*YOURUSERNAME*/Library/Caches/VSL/Vienna Ensemble Pro" as mentionned.
3. I launch VEPRO7 which rescan all the plugins.

4. I put all VST3 plugins from off to VST3 folder
5. I uncheck the "VST3" box in the "Effects" and "Instruments" preferences (if I let it checked, its the same result)
6. I restart VEPRO7 and it crashes in an endless loop by adding a folder in the path "~Users/*YOURUSERNAME*/Library/Applications Support/VSL/SL/Vienna Ensemble Pro/sentry-db". (screen record)
7. The only solution is to press "cancel" each time VEPRO7 is started. Not very smart ;-)

Same behavior here.

I had a toolkit error validation. I deleted the VSL folder in Application Support and reinstalled.

But when trying to scan VST3 plugins, it kept scanning forever, so I was adding one by one fo the vst3 folder until I detected the problematic plugins. reinstalled and all is ok now
