Hello!
I am on Windows 10 Pro x64 a couple of days and have the same problems with Padshop Pro. On Windows 7 Padshop Pro worked without any problem. Now Padshop doesnt work in FL Studio 20.6 and Studio One 4.6. It is really painful and annoying. In Studio One I cant drop to the playlist more than 3 instances of the plugin and, often, the big amount of interface just doesn`t appear(but still has sound).
