I have Studio One 5 Artist which I purchased in July 2020. It supports VST plug ins. Besides the literature telling me so, I know this because I was able to run EZ Drummer Demo with no problems.
I just purchased the full version of EZ Drummer 2 and installed it. Checked and corrected the mapping so that S1 sees the VST file. When I start S1, I can see EZ Drummer in the Instrument list. The problem is when I try to drag and drop it into an existing drum or new instrument track, it looks like it is trying to add it, but nothing happens.
I've checked that I am running 64 bit versions of both. I'm running Windows 10 64 bit with a Focusrite Scarlet 4x4. .
Any help you folks could offer would be appreciated. Thanks.
