When the following controls are grouped with offsets and moved to their extremes, relative offsets are preserved when the controls are moved back from their extremes:
For example, when a grouped Volume fader is moved to its maximum value, any other faders in that group that had higher values will remember their relative offset whenever the first fader is pulled down again.
In Automation views, this “overflow” is indicated on the automation playlist by blue automation breakpoints at the extremes of the automation playlist.
