Hi and greetings from Chile
A couple of hours ago I bought the VST Plug-in Extension for Studio One 3 Artist in order to use EZDrummer2 as VST, but it doesn't seem to be working.
Obviously, the first thing that happend when I started Studio One 3 was the activation process of that said plug-in. After that, I went to Options menu and found no VST tab so I thought that the proper place to set the folder location was in the Instruments tab; after a restart, nothing happened.
Then, I tried reinstalling EZDrummer, both 32 and 64bits with the same results as before; my S1 3 Artist is a 64bit version running over Windows 10. EZDrummer detected my DAW installation folder and placed the dll file in C:Program FilesPreSonusStudio One 3Plugins and again, no EZDrummer
The only thing that I didn't try is reinstalling Studio One, but I like to avoid that.
Any thoughts?
Any help will be kindly appreciated.

I am only assuming.. but I would think that after activating the VST Add On and restarting Studio One the VST Plugin Option box should appear in options.. just as it was for the demo version. From there you can set the folders you want scanned.
Take a look here..
Studio one > Options > Locations > (there should be a VST tab here along with 'user data', 'file types', etc..)
If that doesn't appear you may have to contact Presonus for support.

Studio One Artist does not support third party plugins in general and Presonus & Toontrack no longer have an agreement. I do not believe EZ Drummer can be used in V3.

You might have missed this from the OP..

The purpose of that VST Extension is to allow 3rd party VST usage in V3 Artist.

I very much hope that EZ Drummer 2 can be used in S1v3 ! Can anyone confirm compatibility?

Maybe one day I'll actually finish a project!

Normally you let the VST be install where they natural want to or what I do is install all of the 64 bit as a an example in a 64 bit VST directory.
You have to tell S1 where you VST are at.
Studio One/Options/Locations/VST plugin paths.
Reboot S1 and see if it detects them on the boot up screen.

I use it and it works flawlessly, as with all the other.
I think you need to open a song and then goto the top meny /Studio One/Studio One Extensions/Program Extensions and install the Presonus Cloud Support. Sign in and then you can goto the download for the VST Plugin and activate it on the /Studio One/Activate Purchased Items.
Or at least I think it will work that way. (I have the SO 3 Pro)
Sorry if I missunderstood anything (am going to bed now)

Yeah, I couldn't find the VST tab anywhere, so, prior to writing on the forum, I opened up a ticket.

The activation process was successful as it was the first thing showing up after purchasing the plug-in. Anyway, I will try to do that this afternoon.
I did, reinstall Studio One 3 Artist this weekend, but it was the same, no VST tab.
Again, thank you all for your answers.

SOLVED
Somehow, when I first installed the extension, it failed to activate online (forgetting my password in the middle of the process didn't help at all), so tonight, I decided to uninstall the extension, download it from my account and proceed with an offline manual installation and it worked! (see attach).
Again, thank you

im glad i came across this thread im about to get the VST plug in upgrade..

im starting this same venture,
I have started upgrade from sony daws. I have studio one 3 ARTIST and just purchased the vst upgrade, I can not get SD2 or any of the toon tracks stuff to show up. ive added both the 86X file extensions for the vst folders and nothing.. am I missing something here ?

So let me see if I get this straight. You ARE able to download Vst plug-ins to artist but in order to do so you HAVE to buy and invest in getting the extension Vst plug in for artist so you can use vsts. Ridiculous. But pro.you don't have to? There's other things this Daw needs. I upgraded to 3.2 artist. Now I gotta do that? I need cuz unfortunately this programs slicer is just ok.
