Sculpture delay effect in Logic Pro for iPad

This is a stereo delay that can be synchronized with the project tempo. It can also run freely (unsynchronized).

Sculpture Delay effect parameters

Delay On/Off button: Turn the Delay effect on or off.
Base Time knob: Set the delay time. This can be in either musical note values—1/4, 1/4t (1/4 triplet), and so on (when Time Mode Sync button is on)—or in milliseconds (when Time Mode Free button is on).
Time Mode buttons: Set either free-running (Free) or tempo-synced (Sync) delay modes.
LR Spread knob: Adjust for wide stereo delay effects. Values above the default, centered position increase the delay time of the right delay line or decrease the delay time of the left delay line—in effect, smearing the delay times of the left and right channels. Negative values invert this effect.
LR Groove knob: Distribute delay taps to the left/right channels rather than smearing them across channels, like the Spread parameter. Value adjustments reduce the delay time of one delay line by a given percentage, while keeping the other delay line constant.
For example, a value of +50% reduces the right delay time by half. If a value of 1/4 was used as the Base Time, the right delay would equal 1/8th of a note and the left delay would remain at 1/4th of a note. Needless to say, this parameter is perfect for the creation of interesting rhythmic delays—in stereo.
Input Balance knob: Move the stereo center of the Delay input to the left or right, without the loss of any signal components. This makes it ideal for ping-pong delays.
Feedback knob: Set the amount of delay signal that is routed back from the delay unit output channels to the delay unit input channels. Negative values result in phase-inverted feedback.
CrossFeed knob: Set the amount of delay signal that is fed from the delay unit left output channel to the right input channel, and vice versa. Negative values result in phase-inverted feedback of the crossfed signal.
Lf Damp slider: Determine the cutoff frequency of the highpass filter at the delay line output/feedback loop.
Hf Damp slider: Determine the cutoff frequency of the lowpass filter at the delay line output/feedback loop.
Output Width knob: Change the stereo base of the wet signal. A value of 0.0 results in mono output. A value of 1.0 results in full stereo output—the left delay line output channel is panned hard left, and the right delay line output channel is panned hard right, but the stereo center is unaffected.
Note: This parameter is aimed primarily at achieving pure delay grooves in both channels, without hard left/right ping-pong panning.
Wet Level knob: Set the Delay output level.
