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
.
High Pass Filter
Frequencies below this level are attenuated.
Low Pass Filter
Frequencies above this level are attenuated.
Ducker Level
Ducker Level is the level you want the delay to be heard at when signal is present. This
provides attenuation (up to 18dB) of the delay signal while a performer is singing or
playing to help provide intelligibility. As the performance pauses, the delay signal level
returns to its normal setting.
Ducker Threshold
MX400’s
Studio
and
Digital
delays offer a “ducking” feature, which causes the delay
repeats to attenuate (or get softer) by –6dB when live (or input) signal is present. This
allows the delay to remain as an effect, and not clash with the original signal. The
higher this value is set, the louder an input signal must be for the ducking to take
place.
