Region Gain envelope versus Gain automation
I'm a very new user of Ardour, but am very impressed so far.
What are the differences between implementing gain changes in a track via the region gain envelope versus automation? One difference I noticed is that automation seems to lock the mixer fader for the track, while the gain envelope approach allows the envelope to be scaled by the track fader. Are there other differences I haven't noticed?
Also, can an existing gain envelope (or automation profile) be copied from one region/track to another?
thanks for any help,
