or, the easiest way for small patches - just tell us about it here on the forum (as you have done), and we will forward it to the developer’s mailing list (which I shall do now).
Thanks
If you have a GitHub account, perhaps I could encourage you to post a pull request with this fix.
The Audacity GitHub repository is here: https://github.com/audacity/audacity
There’s due to be a bug-fix release (Audacity 3.0.1) very soon, so I think it would be nice to get this fix in quickly.
- Install a vanilla version of Audacity (and/or delete or move pluginregistry.cfg)
- Make sure there is no VST reg keys : HKCU\\Software\\VST\\VSTPluginsPath and HKLM\\Software\\VST\\VSTPluginsPath
- Make sure plugins dir has no VST plugin inside : Users\\<username>\\AppData\\Roaming\\audacity\\Plug-Ins
- Install a VST plugin in (for example) : C:\Program Files (x86)\VSTPlugIns
- Set VST_PATH environment variable through GUI or command setx VST_PATH "C:\Program Files (x86)\VSTPlugIns"
- Start Audacity. The plugin should now appear in Effect/Add-Remove plugins
Edit : I currently run a custom version version of Audacity that include ASIO and "my" VST fix.
