VAST function to smoothly vary the delay length. The range for all delays and excursions
is 0 to 230 ms, but for flanging the range 0 to 5 ms is most effective.
A fine adjustment to the static delay tap length. The resolution is one sample.
The level of the static delay tap. Negative values polarity invert the signal. Setting any tap
level to 0% turns off the delay tap.
The LFO excursion controls set 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 excursion cannot be made longer than than the delay to the
center of excursion (see Dly Crs & Dly Fin below) because delays cannot be made shorter
than 0. If you attempt longer excursions, the length of the Dly Crs/Fin will be forced to
increase (though you will not see the increased length displayed in the Dly Crs/Fin
parameters). The range for all delays and excursions is 0 to 230 ms, but for flanging the
range 0 to 5 ms is most effective. This parameter is a coarse adjustment for the excursion.
A fine adjustment for the LFO excursions. The resolution is one sample.
The delay to the center of LFO tap range. The maximum delay will be this delay plus the
LFO excursion delay. The minimum delay will be this delay minus the LFO excursion
delay. Since delays cannot be less than 0 ms in length, the this delay length will be
increased if LFO excursion is larger than this delay length. The range for all delays and
excursions is 0 to 230 ms, but for flanging the range 0 to 5 ms is most effective. This
parameter is a coarse adjustment for the delay.
A fine adjustment to the minimum delay tap lengths. The resolution is one sample.
The levels of the LFO modulated delay taps. Negative values polarity invert the signal.
Setting any tap level to 0% turns off the delay tap.
The phase angles of the LFOs relative to each other and to the system tempo clock, if
turned on (see Tempo). For example, if one LFO is set to 0° and another is set to 180°, then
when one LFO delay tap is at its shortest, the other will be at its longest. If the system
tempo clock is on, the LFOs are synchronized to the clock with absolute phase. A phase of
0° will put an LFO tap at the center of its range and its lengthening.
Adds the specified phase angle to the right channel LFOs. In all other respects the right
and left channels are symmetric. By moving this control away from 0°, the stereo sound
field is broken up and a stereo image becomes difficult to spatially locate. The effect is
usually described as "phasey." It tends to impart a greater sense of motion.
