Stereo Delay in Logic Pro for Mac
Stereo Delay lets you set the Delay, Feedback, and Mix parameters 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 effect slots after the chosen slot are stereo.
To add Stereo Delay to your project, choose Delay > Stereo Delay in a channel strip Audio Effect plug-in menu. See Add, remove, move, and copy plug-ins in Logic Pro for Mac.
The parameters for the left and right delays are identical. The following descriptions apply to both channels. Global and Output Mix parameters are described after the channel parameters.
Channel parameters
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 project tempo. Notes (and dots) are displayed around the Delay Time knob when synchronized with the project tempo. Click these buttons 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: Set the grid resolution for the delay time when the Tempo Sync button is active.
Deviation field: Set the amount of deviation from the grid.
: 2 and x 2 buttons: Halve or double the current delay time.
Low/High Cut slider and field: Cut frequencies below the Low Cut value and above the High Cut value from the effect 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 (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 parameters
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 project tempo. Set note values with the Note pop-up menu or Delay Time knob.
Stereo Link button: Turn on to make corresponding parameter 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 mode is not active.
Command-drag a slider to adjust a single channel when in Stereo Link mode.
Note: Stereo Link mode can be automatically disabled when you choose a new routing or setting. Reenable, if required.
Output Mix sliders and fields: Independently control the level of the left and right channel signals.
