Auio and Midi Locked?

In Nuendo 10.3 all my midi and audio is locked i can’t edit by double clicking on it or anything else when it comes to editing. Everything else ok?

Hi,

Can you see the lock symbol on the right side of the MIDI/Audio Parts? Or can you see the Lock symbol on the tracks?

Does Edit > Unlock function help?

Are your tracks Frozen by any chance?
