Just to be clear that is not a warez request and thats also not an opportunity to start some ...

Which Midi Quest version is actual working?

I found the following releases (and also v10 by AIR, but thats probably way to old):
11.0.3 by CORE with keymaker
11.0.3 by AMPED - looks patched
12.1.2 by R2R - this was unpack from shitLok

And then i found all those sqz files from version 12 in one file.

Now are those work with the v11 version? Or do i really need version 12? (found a package on sister page)

As i read version 12 does have VST support?

I want to control some older hardware with it, which doesnt have any other editor.
