The stereo plugin loads just fine, but I get this error "Failed to load Audio Unit “Microtonic ”, please contact the manufacturer for an updated version or further assistance" when trying to load the multi-output version. I am using the 2020.03.22 version of the installer to attempt re-install, but that changes nothing.

Is this still a problem? Did you check with Logic 10.5.1? Logic 10.5 was buggy with Audio Units that had multiple outputs.

On your recommendation, I went ahead and embraced Logic 10.5.1. This update seems to have fixed the multi-output issue in Microtonic, and I seem to have avoided the many headaches people are complaining about online with regards to the new Logic. Thank you.

Great!
