I'm using the build that i have posted earlier indeed. Let me double check.

i rebuilt the plugin and tested it in Bitwig, works fine.

As I'm not that familiar with Mac OS in general, what I have built is a 64 bit version for Mac OS Catalina 10.15.6. Is this correct?

Would be great if someone could test once more. Sorry for the inconvenience.

Still not loading in Ableton or Reason. Reason can see the plugin but its saying that it can't be loaded.

Is it a Catalina-only build? That could explain why it's not working for me, at least. The other reason I can think of that it would work on your system and not others is that you're dynamically linking to some library that's present on your system but not ours.

Don't Mac plug-ins have to be "signed" or something like that now? I've seen a few developers comment on that, and saying they're not paying Apple to have them signed. I don't remember what the specific errors were if the plug-ins weren't signed, but I know it's been an issue recently.

OK, I think I got it... at least partially. :) The issue is probably related to plugin notarization that is now required on OS X.

Meanwhile, there is one trick that might make it work on Mac for now (try at your own risk):

* Open terminal
* cd /your/VST/directory/
* xattr -cr NilsK1v.vst

After this, I was able to load it in the plugin host module of Voltage Modular (before, I got a message that the file is "damaged"). But for some reason Live still doesn't show it in the plugin list (might be some cache issue?).

It doesn't work on my system:
  • Mac mini 2012
  • macOS 10.15.6 Catalina
  • Reaper 6.13 (64Bit) Catalina
If I scan the VSTi plugin in Reaper then I get the following error:

Hi Nils,
I just tried loading the latest build in Cubase Elements on Mojave 10.14.6, and got the following message from Cubase :
The following plug-ins have been added to the Blocklist
/Library/Audio/Plug-Ins/VST/NilsK1v.vst (Not a valid plug-in)

Please Note: 32-Bit Plug-ins are no longer supported!
Thanks for trying though, hopefully you can it get sorted eventually, as I'd really like to try this one !

- Jay

Hi Captain,
I think you’re onto something here.
I’ll give the terminal commands a go once I get back from work

Thanks Captain I've tried this with no success, I've also tried to codesign the plug in using other commands in terminal and it still doesn't show in Ableton, but I've downloaded Bitwig's demo and Nils' K1v is working perfectly there so it must be something to do with Ableton and the codesign process.

It's a really nice synth, I like the vibe and sounds.

Looking at Live's log, I see the following message (even after the xattr terminal command), which seems to support the notion that the plugin needs to be signed/notarized:
error: Code signature verification failed for /Users/captain/Library/Audio/Plug-Ins/VST/NilsK1v.vst with error -67056 (code has no resources but signature indicates they must be present)
But I was able to make it work inside Voltage Modular, and quickly browsed through some of the presets, and... whoa, the nostalgia! :o :D As I said earlier, I still have my K1m in the closet, but haven't used it for, what, 25 years? And I have to say this thing sounds better than I remembered. If I'm not mistaken (and something I didn't pay attention to back in the day, I assume the HW behaves the same way), the looped PCM waves are not restarted with each note, but either have a random start position or are in some kind of freerunning mode, which makes them sound very alive (instead of the typical horrible canned machine gun). Cooool! :phones:

Hello Nils and Captain,
Captain’s terminal command done the trick for both Cubase Pro 10.5 and Reason 11 😀
Ableton Live Suite seems to be more “picky” and just ignores the plugin completely.
Oh well, K1v is working now in my main DAW (Cubase Pro) and Reason, so I’m MEGA happy 😃
Thank you very much Nils for making it happen and Captain for finding work around.
Kind regards

Great to hear that some people got it working!

Just to clarify, the code signing stuff is something that I have to do instead of the end user to get rid of the problems upfront, right? And this only works if I have an Apple Developer account?

Yes that is correct, you’ll also need the latest version of Xcode as well.
Many thanks again 😀
Kind regards
