Adjust the volume for an entire project

This is an extremely stupid question, but can I lower the volume of the entire project or do I have to do it track by track?

Ctrl+A (select All)
then use the Amplify effect and amplify by a negative amount.

hmm i don’t know if i like that answer. Amplify is destructive editing, isn’t it? For such an incredible piece of software, it seems like one of the first things it should have.

Then use the -…+ gain sliders on each track as per your first idea which does not affect the audio data. If you want to ask for a master fader control, just say and we’ll add your vote.
