I have an issue with the Device Control Panel in Nuendo 13. I use an Apollo Twin USB X and possibly with an update the Device Control panel has stopped functioning so I have no buffer settings etc. The Apollo inputs/outputs fine but the CP button does nothing in Studio Setup/Audio System/Universal Audio USB. Anyone seen this before? I’ve been using the Apollo twin for years but this has surfaced in the last months.
Make sure it is up-to-date.
New firmware, new software, updated plugins. There were some changes in the last few months.
Can you open the settings inside Console?
