Stereo Tap Delay - Provides a clean digital delay with a maximum delay time of 2.7 seconds. One of the
key features of the stereo tap delay is the ability to synchronise the delay times to note intervals based on
the effects beats per minute value. The delay has two modes of operation:
BPM mode -Delay time is determined by the selected beats per minute and corresponding note value.
Standard, dotted and triplet intervals are selectable via the interval selection wheel from whole to 16th
intervals.
MS mode - Delay time is set directly in milliseconds. The unit offers control over input and feedback filters,
delay width and switchable Scatter/Ping-Pong modes.
Input filter HP frequency – Sets the frequency of the high pass filter on the input to the delay. This cuts low
frequencies.
Input filter LP frequency – Sets the frequency of the low pass filter on the input to the delay. This cuts high
frequencies.
BPM / MS mode –Switches between Beats Per Minute and Milliseconds mode. In BPM mode the BPM and
note selection wheels are displayed allowing delay times to be set as an interval of a selected BPM.
Interval Selection Wheel – Determines the delay time to be set in synchronisation with the chosen BPM.
The values range from whole dotted intervals to 16th triplet notes. When an interval is not available due to
the BPM being too low, the interval will grey out and not be selectable.
MS time window (in MS mode) – Allows the delay time to be set directly in milliseconds.
Link – Links the left and right delay times.
Fractional / Notation display – Choose to display either fractions or notation representation of the selected
interval on the selection wheel.
Feedback filter frequency – Selects the frequency of the filter in the feedback path of the delay unit.
Feedback filter slope – Selects the slope of the feedback filter. A larger slope provides greater feedback
attenuation.
Scatter mode – Modifies the delay pattern between Ping-Pong and scattered. Scatter off creates classic
Ping-Pong delays. Scatter on reconfigures the regen path giving one delay on the shortest side and regen
on the longest side replacing Ping-Pong bounce with some interesting delay patterns. For example, an echo
on one side and a regen echo pattern on the other.
Feedback – Controls the amount of the feedback in the delay. A larger amount increases the number of
audible repeats.
Width – Controls the stereo imaging of the delay unit, from focussed mono sounding to panned wide stereo
delays.
