Delay pedals in Logic Pro for Mac

This table describes the Delay effects pedals.

Stompbox	Description
	Blue Echo is a simple delay effect. On/Off switch: Turn on or turn off the pedal. The LED indicates the pedal state. Time knob: Set the modulation speed in hertz, or synchronized with the host tempo when you turn on the Sync button. Repeats knob: Determine the number of delay repeats. Mix knob: Set the level balance between source and effect signals. Tone Cut switch: Choose a fixed frequency internal filter circuit that allows more low (Lo) or high (Hi) frequency content to be heard. Choose Off to turn off the filter. Mute button: Passes the source signal through to the next pedal, while delay repeats continue. Sync button: Turn on to synchronize the Time value with the host tempo.
	Spring Box emulates a spring reverb effect. On/Off switch: Turn on or turn off the pedal. The LED indicates the pedal state. Time knob: Set the length of the reverberation to short, medium, or long values. Tone knob: Set the cutoff frequency, making the effect brighter or darker. Style knob: Switches between algorithms, each with different characteristics. You can choose Boutique, Simple, Vintage, Bright, or Resonant. Mix knob: Set the level balance between source and effect signals.
	Tie Dye Delay is a warm-sounding reverse delay effect that’s perfect for fans of 1960s and 1970s psychedelic rock. On/Off switch: Turn on or turn off the pedal. The LED indicates the pedal state. Time knob: Set the modulation speed in hertz, or synchronized with the host tempo when you turn on the Sync button. Feedback knob: Set the amount of effect output sent to the effect input, changing the tonal color, making the effect more pronounced, or both. Tone knob: Set the cutoff frequency, making the effect brighter or darker. Bright/Dark switch: Both positions apply a fixed frequency internal EQ. Mix knob: Set the level balance between source and effect signals. Listen button: Passes the source signal through to the next pedal while delay repeats continue. Sync button: Turn on to synchronize the Time value with the host tempo.
	Tru-Tape Delay emulates a vintage tape delay effect. On/Off switch: Turn on or turn off the pedal. The LED indicates the pedal state. Norm/Reverse switch: Change the delay playback direction. LED color indicates the switch state. Lo/Hi Cut knobs: Adjust the range of the fixed frequency internal EQ. Dirt knob: Set the amount of input signal gain, which can introduce an overdriven, saturated quality. Flutter knob: Emulate speed fluctuations in the tape transport mechanism. Sync button: Turn on to synchronize the Time value with the host tempo. Time knob: Set the modulation speed in hertz, or synchronized with the host tempo when you turn on the Sync button. Feedback knob: Set the amount of effect output sent to the effect input. The buildup of repeating signals can be used creatively for dub-delay and other effects by adjusting Feedback in real time. Mix knob: Set the level balance between source and effect signals.
