MusicTechHelpGuy walks through absolute pan automation in Logic Pro, using it to push a vocal left, bring it back to center, then swing right for a creative stereo effect.
If a hard pan jump feels too abrupt, ramping the move instead of snapping it creates smoother stereo motion, a trick that works especially well on software instrument tracks.
He also shows a quieter but handy fix: using Delete Visible Automation to wipe out pan automation on a track while leaving existing volume automation untouched.
