The DAW control works perfectly for about 1.5 hours then the “can’t communicate” message pops up and the daw driver disappears and has to be restarted. Once that happens Protools must be restarted to get the control surface to respond again. It seems to be more of an issue when recording/mixing. Just letting Protools sit idle will not cause the :can’t communicate” message to come on. I,m using Protoola 2020.5 and I know Avid is not supporting the HUI format any longer but they have left the legacy Protol in place or so I,m told. The same issue happens with the SQ6 on 3 different computers so it doesn’t appear to be hardware related.
