The Delay effect pedal gives the effect of a repeating, decaying echo. The Delay effect pedal works by sampling the input signal and storing it in a buffer. The stored audio sample can then be played back, adhering to the parameters set with the effects controls.
steps - Allows control over how many steps before the delay starts after the original signal is played.
length - Allows adjustment of the length of the Delay in relation to the BPM or time scale of the song. (steps multiplied by length equals the duration of the delay)
feedback - Allows control over how much of the processed signal is fed back through the device.
level - The Level is the volume of the processed delay signal in relation to the unprocessed, original signal.
