VST Icons

Can someone tell me what the following icons before each plug-in mean? I’ve looked through the manual and can’t find it, but I might have just over looked it.

/// means VST 3
// means you are using x64 and that one will load via the bridge
Haven’t seen D before. Only thing I can think of is that it indicates one of those extra special integrated controller setups.

I didn’t know Stylus had an x64 version. Interesting.

Thanks, that’s what I was thinking. Actually D was the only one I knew, and it means External Hardware.

Yep, Stylus is now x64. Slowly, more and more vsts are getting x64. Can’t wait until everything is x64!

I have lots of external hardware set in VST Connections that doesn’t have a D. That’s why I thought it had to be specific to one of the Steinberg supported interfaces.
