which is why you should not do volume automation except for the actual mixing.
to fix it if already done: if you don't have track-groups, group the tracks to get a "secondary" volume. if needed, individually.
to prevent it: use utility or similar on a track for the musical non-mixing automation.
i think that's about it? anyone else?
The thing about telling Ableton users to not automate volume pre final mix is, it's asking us to be limited like it's analog console mixing again. This is digital audio, volume automation shouldn't be limited to the the final mix process with modern DAWs. It's why we involve ourselves with digital audio.
All we need is one, or both of two possible solutions. One, changing the track volume should also change the over all track volume automation relatively. Two, Ableton should at least show you the volume automation dB level as you drag it up or down. You have to guess you dB level as you change it. Unsung problem.
Fix it Ableton. I still think you're neat though.
...the Utility track prevention idea is genius though.
