Just tried a quick test with Superplugin. It sort-of works, i.e. I can open an existing patch and hear its output through Mainstage. But there are definitely some glitches:
I’ve not done any extensive testing, but works for me so far with latest (trial) version of blue cat patchwork. There are 3 versions of the AU-plugin visible after installation and only one of them worked when loading vcv rack. You need to deselect lock cursor while draggning to use the mouse turning knobs… Patching, saving presets, presets re-appearing when opening up worked for me
Yes that works here too running Logic as M1 native app. Thanks a lot 
But yeah, it seems like it is only the Patchworks SYNTH plugin that works, I can only use VCV as an instrument. If I try to load VCV as an effect, I get this error, no matter if I use VCV Rack 2 FX or VCV Rack 2. As an effect none of them works, but as instrument VCV Rack 2 works:
What MAC are you on?? Whic kind of HW?? Which kind of Os???
Please always share your Mac specs, as it makes a ton of difference… M1 macs Logic and Garageband are M1 Native… There should be Rosetta Bridge working in the background but I’m no Guru. I just jumped on the M1 Mini bandwagon also…
The info is there a few posts up 
Not sure what you are saying?
Just emailed vcv support. Really need an AU plugin because I’m mostly depending on Logic for mixing/editing. Ableton is doable but not ideal for me.
Reply from vcv support:
“Thanks for purchasing VCV Rack 2 Pro! We’d like to add an Audio Unit version of Rack 2 Pro in the future, but we don’t currently have a time estimate of this feature.”
I really need this AU version. Let’s hope it’ll come soon…
I just tried the open source software Element and successfully set up VCV in Logic. I had a couple of crashes of the whole thing on my first tests, seems like Element needs to index some things before running fine, but now it’s working :
I haven’t tried in depth yet, but it seems you can route 16 audio channels and the midi channels in and out to/from VCV and Logic trough Element ! Nice
Nice! If you could update us after a bit more testing, that would be great. Especially regarding MIDI Sync stability and latency.
I did a few more experiments, I still had some full Logic crashes when opening/closing plugin windows in Logic, Element and VCV… I will try to get in touch with the Element developers to find out what is going on. But mostly it is stable.
I’m planning to use an Arturia KeyStep Pro, and I want to route the KeyStep channels to multiple instances of VCV Rack or other instruments. Here I created :
I didn’t find yet is how to get the Element’s multiple audio outputs back into different audio tracks in Logic for recording the VCV Racks instances separately.
I’m not sure this process will be handy but it’s a solution for now, I get VCV Racks as multiple software instruments through Logic which is what I wanted !
As for Midi sync and latency, until now it’s working fine.
For those coming to this post from Google like I did, it appears that AU is now supported which implies that Logic is also supported. I have not tested this myself.
