No clue about AUv3 on macosx

[holzon]

Hi!
I’ve been confused for awhile now about what the heck an AUv3 component on macosx actually is… I entered a plug-in in the KVR Developer Challenge that I thought had been built for AUv3 as well for macosx, but I’m not so sure anymore.
In the build directory there is an .appex file, this is what I thought was the AUv3 component. Is this correct?
How do you actually install it? Double-clicking it launches some Widget Simulator. Does it have to be embedded in a standalone app or something?

Anyway, if anyone actually knows how these things work, I would be super grateful!

Cheers,
Jens

No, AUv3s work on MacOS too…

Audio Unit Extensions - WWDC15 - Videos - Apple Developer

Some tips which I don’t think are in the video:

• You’ll need to codesign everything
• You’ll probably need to restart your computer after first building the project:

Installing new Audio Units requires restart in High Sierra

Since macOS High Sierra, installing Audio Unit plugins seems to always requires a restart (or at least a re-login) before hosts see them. Even though we noticed it for all plugins we checked, some folks report that “some AUs require restart, some don’t”. Does anyone know more about this? Is there any special juice required for new AUs to be listed? If so perhaps this juice could be incorporated into JUCE? Is there something new that installers need to do?

• You should run the standalone target once (the debugger in Xcode is enough)
• You’ll need to hit a tickbox in Logic’s plug-in manager to allow the AUv3 plug-in to load
• Debugging after load is awkward - you’re in a separate process, console output doesn’t work, and you’re probably sandboxed too

Sorry for the late reply,
Thanks a ton, that’s a lot of good information!

Cheers!

thanks - i should have updated this, i did find that option after i discovered the weirdness with having to run the standalone app once to register the auv3 plugin.
