Thanks for the tip. But as the manual states, inserting the VST Connect Cuemix plugin into a cuemix channel unfortunately does not allow for sample synchronous recording, because the delay compensation doesn’t work for Controlroom Mixer Studio Channels (aka cuemix channels), thus recordings of the Performer are out of sync.
Nevertheless it makes sense when one only wants to review mixes, so we will have an option to disable that warning. Thanks for pointing this out.
