Stereo Delay in Logic Pro for iPad

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 Audio Effect slots after the chosen slot are stereo.

To add Stereo Delay to your project, choose Delay > Stereo Delay in the Plug-ins area or a channel strip Audio Effect plug-in menu. See Intro to plug-ins. Also see Add, replace, reorder, and remove plug-ins in the Plug-ins area and Work with plug-ins in the Mixer.

The parameters for the left and right delays are identical. The following descriptions apply to both channels. Global and Output Mix parameters are described below the channel parameters.

Channel parameters

Input pop-up menu and field: Choose the input signal for the two stereo sides. Options include Off, Left, Right, L + R, and L − R.
Note pop-up menu and field: Set the grid resolution for the delay time when the Beat Sync button is active.
Deviation field: Set the amount of deviation from the grid.
Double and Halve Time buttons: Double or halve the current delay time for the channel.
Sync or Delay Time knob and field: Set the delay time in milliseconds or in note values when the Beat Sync button is turned on. Note (including dotted note) values are displayed in the Note pop-up menu field when Stereo Delay is synchronized with the project tempo.
Note: Choosing note or dotted values with the Sync Time knob resets the Deviation parameter value. Choose a value from the Note pop-up menu to retain the current Deviation value.
Low/High Cut sliders and fields: 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 buttons: Choose a normal or inverted phase of the corresponding channel feedback signal.
Crossfeed L->R (R->L) knob and field: Transfer the feedback signal of the left channel to the right channel, and vice versa.
Crossfeed L->R (R->L) Phase buttons: Choose a normal or inverted phase of the crossfed feedback signals.

Global and Output Mix parameters

Routing Preset pop-up menu: Choose the internal signal routing. Options include: Rotate L/R, Pan L/R, Ping Pong L/R, 10/90, 90/10, Straight, and Customized.
Beat Sync button: Synchronize delay repeats with the project tempo. Set note values with the Note pop-up menu or Sync 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.
Note: Stereo Link mode can be automatically disabled when you choose a new routing or setting. Re-enable, if required.
Output Mix sliders and fields: Independently control the level of the left and right channel signals.
