@LarsBjerregaard pointed out that in VCV 2 it is still possible to subscribe to a whole plugin. But since updating I am no longer subscribed to any modules, and I can’t find the button. Even modules I had not subscribed to before don’t seem to have buttons.
If you click on the green bordered “Instruo” name, doesn’t that take you to the view which lists everything included in that plugin, and lets you subscribe to the whole of it?
Can’t you just go to https://library.vcvrack.com/plugins and subscribe to the plugin? On that page you can also add all the modules in the plugin, if you have previously only selected some of them.
