Drag an automation point beyond a point to its left or right to delete it. When a track is muted with automation, the data isn't processed during playback so processing time is reduced. This can be useful for projects where some tracks are used some of the time and other tracks are used other times, but you don't have enough processing power to play all of the tracks simultaneously. For regions where the PAN or FADE is to remain constant, decrease processing time by setting the begin and end automation points equal. FADE sections of value oo are treated as muted to reduce processing.
Automation is processed before the console.
Cut and paste automation points from the EDIT menu. Cursor and Page keys - allow you to zoom and move around the waveform as indicated in the VIEW menu. This is the preferred method for zooming. Cursor keys - allow you to adjust the levels. Cursor keys - allow you to adjust all the fades at the same time and scroll up or down.
