18.10. FILTER DELAY 252
The Filter Delay provides three independent delay lines, each preceded by linked low-pass
and high-pass lters. This allows applying delay to only certain input signal frequencies, as
determined by the lter settings. The feedback from each of the three delays is also routed
back through the lters.
Each of the three delays can be switched on and off independently. The Filter Delay plug-in
assigns delay 1 to the input signal's left channel, delay 2 to the left and right channels and
delay 3 to the right channel. The Pan controls at the right can override the delay channels'
outputs; otherwise each delay outputs on the channel from which it derives its input.
Each delay channel's lter has an associated On switch, located to the left of each XY
controller. The XY controllers adjust the low- and high-pass lters simultaneously for each
delay. To edit lter bandwidth, click and drag on the vertical axis; click and drag on the
horizontal axis to set the lter band's frequency.
To refer delay time to the master tempo, activate the Sync switch, which allows using the
Delay time beat division chooser. The numbered switches represent time delay in 16th
notes. For example, selecting 4 delays the signal by four 16th notes, which equals one
beat (a quarter note) of delay. With Sync Mode active, changing the Delay Time eld
percentage value shortens and extends delay times by fractional amounts, thus producing
the swing type of timing effect found in drum machines.
If the Sync switch is off, the delay time reverts to milliseconds. In this case, to edit the delay
time, click and drag up or down in the Delay Time eld, or click in the eld and type in a
value.
Feedback controls how much of the output signal returns to the delay line input. Very high
values can lead to runaway feedback and produce a loud oscillation watch your ears and
speakers if you decide to check out extreme feedback settings!
Each delay channel has its own volume control, which can be turned up to +12 dB to
compensate for drastic ltering at the input.
The Dry control adjusts the unprocessed signal level. Set it to minimum if using the Delay
