Faders jump 10.8db down for no reason!

Hi

Very strange. Started happening today. Faders jump 10.8db down for no reason.
This happens on channels that do not have any automation.

Any ideas?

Probably you have recorded some volume automation on the track. Clear automation.

no automation.
figured out. problem stopped when i disconnected the fader controller.
I think I didn’t update Cubase with it’s DLL after the last Cubase upgrade.

Probably a midi port setup issue where you are sending a midi signal to all midi ports.
Have a look at your midi setup, something could have reverted to a default setting.
