This is bullshit. You can also drag and drop it in Cubase from the right panel. Just as quickly. If you don't use custom VST instrument sets, it will also automatically populate the view just like Studio One. However, the behavior which Studio One shows is not always desired. Hence why, if you use custom VST instrument sets, it doesn't automatically show up. Cubase has got this one right over Studio One, because automatically adding it is not always desired (such as when installing a 100 plug-ins all at once).
This is not to demean you
@easyrider but I call bullshit when I hear it.
