4-17
Tap Pan
sets the stereo position for a given tap’s output. The range is -100% for fully left, to
100% for fully right.
Atk Time
(attack time) is the time for the gate to ramp from closed to open (reverse if
Ducking is on) after the signal rises above threshold, adjustable from 0.0 to 228.0 ms.
Rel Time
(release time) is the time for the gate to ramp from open to closed (reverse if
Ducking is on) after the gate timer has elapsed, adjustable from 0 to 3000 ms.
LFO Rate
sets the speed of modulation of the delay lines with a range of 0.01 to 10 Hz.
LFO Dpth
sets the maximum detuning depth of the LFO-modulated delay lines, with a
range from 0 to 50 cents (= 1/2 semitone).
Tap Dly
adds extra delay in front of the LFO modulated delay taps from 0 to 230 ms.
L/R Phase
or LFOn LRPhs adjusts the relative phases of the LFOs for the left and right
channels in the stereo Choruses.
Flanger
Flanging is the process of adding or subtracting a signal with a time-displaced replica of itself,
which results in a series of notches in the frequency spectrum, generally referred to as a comb
filter. In the PC4, the flanger is a multi-tap delay line, all (but one) of whose taps can have
their lengths modulated up and down by a low frequency oscillator (LFO). The rate of the
LFO is expressed in Tempo.
StatDlyLvl
(Static Delay Level) is the level of the first, non-moving tap. Negative values
invert the polarity of the tap. The range is -100 to 100%; 0% turns the tap off.
DlyCrs
and DlyFin are the coarse and fine length controls for the Static delay (StatDly...)
and for the minimum value of the moving delays (Dlyn...). The coarse range is 0 to 228 ms,
and the fine range adjusts the coarse range in samples (= 1/48,000 sec = 20.8μsec) from -127
to 127.
Xcurs Crs
and Xcurs Fin determine how far the LFO-modulated delay taps can move from
the center of their ranges. The total range of the LFO sweep is twice the excursion. If the
excursion is set to 0, the LFO does not move and the tap behaves like a simple delay line set
to the minimum delay. The coarse range is 0 to 228 ms; the range 0 to 5 ms is most effective
for flanging. The fine range adjusts the coarse range in samples from -127 to 127.
Quantize
This effect produces digital distortion known as quantization noise, by limiting the number
of bits available to the signal. See effect 329 “Aliaser.”
