Envelope Phaser
I/O Mode
This parameter sets the input and output and
modulation routing for the phase shifter.
There are 5 different I/O modes:
•
Mono L -
In this mode, the right input channel of the Envelope Phaser
is ignored. The left and right phase shift networks are connected in
series for a total of 22 stages, and the left input channel supplies both
the audio input and the envelope follower input. The output is mono-
phonic.
•
Stereo -
In this mode, the Plug-in operates as a true stereo phase shifter,
with separate signal paths for the left and right input channels. The
envelope follower input is derived from the scaled sum of left and right
inputs.
•
Stereo Inverted -
In this mode, the Plug-in operates in stereo, as for Ste-
reo mode, but the envelope signals driving the phase shifters are
inverted between the left and right sides. This produces a highly spatial
phasing effect in which the “motion” in the left channel is always
matched with an inverted motion in the right channel.
•
Mono L/Env R -
This mode is the same as Mono L, except that the
envelope signal is derived solely from the right input channel (this is
typically referred to as a “sidechain” input.) This allows right channel
control signals that may be unrelated to the left channel audio input to
drive the phase shifter, allowing cross-modulation between the enve-
lope of one signal and the audio of another.
•
Mono Inv L/Env R -
This is similar to the Mono L/ Env R side-chain
mode, except that the left input signal is applied to both left and right
sides of the phase shifter. The phase shifter then operates in the same
way as for Stereo Inverted mode, with the left and right output chan-
nels showing inverted modulation.
MIDI Modulation Parameters
The modulation parameters are used to dynamically rescale several of the
user-editable parameters. Those user parameters should be set to the
maximum desired values; these maximum values are then modulated by
the corresponding modulation parameters.
Mod Offset
- This modulation input is used to dynamically rescale (from 0
to 100%) the offset specified by the user Mod Offset parameter. The
resulting offset is the bias that is applied to the phase shifter before
envelope modulation takes place.
(This parameter was not present in the RFX
Phaser Plug-in.)
Mod Range
- This modulation input is used to dynamically rescale (from 0
to 100%) the phase shift range specified by the user Mod Range parameter.
The resulting phase shift range is then further rescaled by the output of the
envelope follower before being applied to the phase shifter.
Feedback
- This modulation input is used to dynamically rescale (from 0 to
100%) the amount of feedback specified by the user feedback parameter.
