I'd like to have Logic Pro's automation feature work as in other DAWs where even if you have track automation or "envelopes" applied to a track, you can still use the track faders in the mixer to affect the general volume of the track, instead of having the automation actually move the faders. Is that possible?
One solution would be to have the output of the track go to a bus, instead of output 1-2. Then you could either used the fader on the bus, instead of the track, or you could put the automation on the bus track (your would need to create a track for the bus to be able to automate on it).
You could also use a plugin and automate the output volume of the plugin instead of automating the track volume. You would want to make sure the plugin is the last in the signal chain for that track to avoid the automation affecting other aspects of the signal chain.
