Stereo Delay controls in Final Cut Pro
Stereo Delay lets you adjust the Delay, Feedback, and Mix controls separately for the left and right channels. The Crossfeed knob (for each stereo side) sets the feedback intensity level of each signal being routed to the opposite stereo side. You can use Stereo Delay on mono tracks or busses when you want to create independent delays for the two stereo sides.
Note: If you use Stereo Delay on mono channel strips, the track or bus switches to two-channel operation from the point of insertion—all Insert slots after the chosen slot are stereo.
For information about adding the Stereo Delay effect to a clip and showing the effect’s controls, see Add Logic effects to clips in Final Cut Pro.
The controls for the left and right delays are identical. The following descriptions apply to both channels. The Global and Output Mix controls are described after the channel controls.
Input pop-up menu: Choose the input signal for the two stereo sides. Options include Off, Left, Right, L + R, and L − R.
Delay Time knob and field: Set the delay time in milliseconds or in note values when synchronized with the clip. Notes (and dots) are displayed around the Delay Time knob when synchronized with the clip. Click the notes or dots (or rotate the knob) to choose an exact synchronization value.
Note: Clicking note or dot values resets the Deviation parameter value. Choose a value from the Note pop-up menu to retain the current Deviation value.
Note pop-up menu: Choose the grid resolution for the delay time when Tempo Sync is turned on.
Deviation field: Set the amount of deviation from the grid.
Delay Time : 2 and x 2 buttons: Halve or double the current delay time.
Low Cut and High Cut slider and field: Cut frequencies below the Low Cut value and above the High Cut value from the source signal.
Feedback knob and field: Set the amount of feedback for the left and right delay signals.
Feedback Phase button: Invert the phase of the corresponding channel feedback signal.
Crossfeed Left to Right (or Right to Left) knob and field: Transfer the feedback signal of the left channel to the right channel, and vice versa.
Crossfeed Phase button: Invert the phase of the crossfed feedback signals.
Global and Output Mix controls
Routing pop-up menu: Choose the internal signal routing. Options include Customized, Straight, Crossfeed, 90/10, 10/90, Ping Pong L/R, Pan L/R, and Rotate L/R.
Tempo Sync button: Synchronize delay repeats with the clip. Set note values with the Note pop-up menu or Delay Time knob.
Stereo Link button: Turn Stereo Link on to make the same adjustments for both channels. Adjusting one channel value adjusts the other. Relative values are maintained.
Press Command to temporarily flip stereo linking, allowing you to adjust a control in a linked fashion even when Stereo Link is not turned on.
Command-drag a slider to adjust a single channel when Stereo Link is turned on.
Note: Stereo Link can be automatically turned off when you choose a new routing or setting. To turn it back on, click the Stereo Link button.
Output Mix sliders and fields: Independently control the level of the left and right channel signals.
