Hi,
Unfortunately this is not so simple. Cubase has 2 factors of VST plug-in verification. The “big one” is triggered when a new plug-in is loaded to Cubase for the 1st time. If this test doesn’t pass, the plug-in becomes blocklisted. Once the plug-in has passed this big test, there is only fast-check test during the next starts. Unfortunately if you update any plug-in, Cubase cannot recognise, this is an update (something has changed in the plug-in). So even in this case only the fast-check test has been triggered. But if the update breaks the plug-in (so it wouldn’t pass the big test), Cubase can’t find it out. The only way would be to trigger the big test manually from the Plug-in Information window.
And of course, as always, even the big test doesn’t test everything (this is just impossible). So it might happen, the plug-in is crashing even though the test passed.
