Note
The original Instant Flanger had two unique outputs called Main and Aux. The Main
output used two bucket brigade devices in series, while the Aux output only used a single
Bucket Brigade. This means the delay times of the Main output are roughly double that of
the Aux output. The Mode control gives you access to which of these outputs is used by
the Algorithm, and it can drastically change the sound.
In Shallow mode, all outputs will correspond to the Aux output of the hardware unit.
In Deep mode, all outputs will correspond to the Main output of the hardware unit.
In Wide mode, the Main output is routed to the left channel and the Aux output is
routed to the right channel. Because of the different delay lengths and the fact that
Main and Aux are out of phase with each other, Wide mode will sound like it is panning
the signal to the left or right, depending on how the Depth knob is set.
Note that if you are using a mono output, Wide mode will be the same as Deep mode.
Rate: Controls the rate of the LFO between 0.01 Hz and 20 Hz.
LFO Width: Adjusts the range of the sweep of the Flanger’s LFO. 100 is the widest possible sweep
and equivalent to the range of the original hardware.
Env Thresh: Controls the threshold of the envelope follower, between
−
60 dB and 0 dB. An input
signal will cause the biggest phase shift when it reaches the threshold level.
Env Release: Sets the release time of the envelope follower. Release times can vary from 10
milliseconds to 10 seconds.
Feedback: Controls the feedback of the
fl
anger output. 0% sends none of the output back to the
input to the bucket brigades, and 100% sends the maximum amount of output back to the input of
the bucket brigades.
Low Cut: Applies a high-pass
fi
lter to the input signal before it is delayed. The original signal is still
mixed with the output of the delays, but the
fl
anging effect only acts on high frequencies.
Manual: Provides manual control of the
fl
anging. 0% corresponds to setting the bucket brigades to
their longest delay times, while 100% sets them to their shortest.
