20.10 Filter Delay
The Filter Delay Effect.
The Filter Delay provides three independent delay lines, each preceded by linked lowpass
and highpass 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 device
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 X-Y
controller. The X-Y controllers adjust the lowpass and highpass 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 song 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.
