Cannot load Amplitube 5 in Cubase Pro 11

Has anyone successfully loaded Amplitube 5 as a VST in Cubase?

I installed and authorized Amplitube 5 on a new iMac using IK Product Manager. Then I attempted to load Amplitube as an insert in Cubase and it failed with a dialog saying “This plug-in has been moved to the blocklist. 32-bit plug-ins are no longer supported.”

Subsequent attempts to load Amplitube 5 in Cubase cause Cubase it to crash.


  • IK Product Manager 1.0.2.
  • Amplitube 5
  • Cubase 11 Pro
  • macOS Catalina 10.15.7
  • iMac 2020 5K


Make sure, you install 64-bit version of the plug-in (only), please.

Could you attach the *.crash file, please?
Mac: macOS Console utility > User Reports folder or Crash Reports in macOS 10.15 (or ~user/Library/Logs/Diagnostic Reports).

Hi Martin,

The crash file is attached. There’s no 32-bit version of Amplitube 5, it is 64-bit.

Thanks, (20.8 KB)


The crash is clearly in the AmpliTube5:

Please, get in contact with IK.

Hi Martin,

Thanks for your response. I am in touch with IK, of course, and they are investigating. Note that on the same machine I also have Ableton Live 10, and it loads Amplitube 5 just fine. So I have not ruled out the possibility that the problem is with Cubase.


On Mac, Ableton is using AU plug-ins type, but Cubase is using VST plug-ins type. So it might be, the bug is in the VST version of the plug-in only.
