67Logic Pro Effects
Logic Pro Echo
This simple echo effect always synchronizes the delay time to the project tempo, enabling
you to quickly create echo effects that run in time with your composition.
Echo parameters
• Note pop-up menu and knob: Choose the grid resolution of the delay time in musical
note durations, based on the project tempo. Notes (and dots) are displayed around the
Note knob when synchronized with the project tempo. Click these buttons or dots (or
rotate the knob) to choose an exact synchronization value.
• : 2 and x 2 buttons: Halve or double the current delay time.
• Feedback knob and field: Determine how often the delay effect is repeated.
• Color slider and field: Set the harmonic content (color) of the delay signal.
• Dry and Wet sliders and fields: Set the amount of original and effect signal.
Logic Pro Sample Delay
Sample Delay is more a utility than an effect—you can use it to delay a channel by single
sample values.
When used in conjunction with the phase inversion capabilities of the Gain effect,
Sample Delay is useful for correcting timing problems that may occur with multichannel
microphones. It can also be used creatively to emulate stereo microphone
channel separation.
Every sample at a frequency of 44.1 kHz is equivalent to the time taken for a sound wave to
travel 7.76 millimeters. If you delay one channel of a stereo microphone by 13 samples, this
emulates an acoustic (microphone) separation of 10 centimeters.
