Effects Descriptions
Pong Delay -
Mono In/Stereo Out
This delay effect pans the delay repeats from left to right, while the input signal
remains at its original (center) position. Pong Delay offers up to 5 seconds of mono
delay time.
Modulated Delay -
Stereo
The Modulated Delay is enhanced by an LFO (low frequency oscillator) that
produces a chorusing effect on the delay repeats. This is a great delay for guitar and
instrument passages that need that "special something." The Modulated Delay
features up to 2.5 seconds of stereo modulated delay.
Reverse Delay -
Mono In/Stereo Out
This delay effect emulates the old studio trick of flipping a tape over, playing it back-
wards through a tape delay, and recording the effect. The delays "build up" from softer
to louder – creating the sensation that the delays come before the signal. Up to 2.5
seconds of mono delay time are available.
2-Tap Delay -
Stereo
The 2-Tap Delay is probably best described as an adjustable pong delay where each
tap can be individually set in relation to the delay time. The 2 taps are a calculated
percentage of the actual delay time from 1-100% (for example, if the delay time is
500ms and Tap 1 is set to 50% and Tap 2 is set to 100%, Tap 1 time would be 250ms
and Tap 2 time would be 500ms). Narrow spacing of the tap percentages can widen
the stereo image of the delay while wider tap spacing can create rhythmic delay lines.
Delay Controls
Tempo
The actual delay time as tapped in by the Tempo button or received via a MIDI clock
source. This time can be expressed as actual time (milliseconds, seconds) or in BPM
(beats per minute) values. Tempo works in conjunction with Delay Range to set the
actual delay time that is heard.
Delay Time
Controls the length of the delay time relative to Tempo. At the middle of its range,
delay repeats are synchronous with the Tempo button (represented by a Quarter Note
in the display); lower values create faster repeats, while higher values increase the time
between repeats.
Feedback
Controls the number of delay repeats by feeding the delay output signal back into the
delay input. This creates a series of delay repeats, each slightly attenuated until they
become inaudible. Higher settings create more repeats; lower settings reduce the num-
ber of repeats. When this knob is turned fully clockwise, it engages Repeat Hold – delay
repeats play back in an infinite loop, but no further input signal is introduced into the
delay effect. Repeat Hold is available only on Studio, Digital and Pong Delay.
