Issue: When opening a saved project that has iZotope Neutron 3 on a group track, the track routed to it will be out of sync.
Work-around: Simply bypass Neutron 3 and then re-enable it to fix the issue.
This affects both Cubase 11 and Cubase 12. The issue is not present in Studio One and appears to be a simple delay compensation issue that sorts itself out once it’s bypassed and then re-enabled.
Tested on Mac OSX Catalina
Mac Pro 2013 model
Ran snare to “SNARES” group and had Neutron 3 on the snare group track.
