First make sure you've followed the installation instructions successfully.
However there are additional complications in some cases.
My Mac host doesn't see the new plug-in
It is likely you are using a 32-bit host, like Ableton 9 32-bit version. Please check the former versions of our products.
My Audio Unit host doesn't see the new plug-in
If you are on macOS 10.13 (High Sierra) or later and use an Audio Unit host, please reboot your computer after installation.
I am a Pro Tools First user
Pro Tools subscription does not support the same set of plug-ins than a regular Pro Tools. We do not support such a host.
In other cases, contact us by email and we'll sort it out.
