(Note: the Phaser effect is not available in the Lite Edition.)
Phaser uses a series of all-pass filters to create a phase shift in the frequency spectrum of a
sound.
The Poles control creates notches in the frequency spectrum. The Feedback control can then be
used to invert the waveform and convert these notches into peaks (or poles). Filter cutoff frequen-
cy is changed with the Frequency control, which can be adjusted in tandem with Feedback using
the effect’s X-Y controller.
The device has two modes, Space and Earth, for changing the spacing of notches along the
spectrum, and hence the ”color” of the sound. This effect can be further adjusted with the Color
control.
Periodic control of the filter frequency is possible using the envelope section. You can increase or
decrease the envelope amount (or invert its shape with negative values), and then use the Attack
and Release controls to define envelope shape.
Phaser contains two LFOs to modulate filter frequency for the left and right stereo channels. The
LFOs have six possible waveform shapes: sine, square, triangle, sawtooth up, sawtooth down
and random. The extent of LFO influence on the filter frequency is set with the Amount control.
LFO speed is controlled with the Rate control, which can be set in terms of hertz. Rate can also
be synced to the song tempo and set in meter subdivisions (e.g., sixteenth notes).
The Phase control lends the sound stereo movement by setting the LFOs to run at the same fre-
quency, but offsetting their waveforms relative to each other. Set this to ”180”, and the LFOs will
be perfectly out of phase (180 degrees apart), so that when one reaches its peak, the other is at
its minimum.
Spin detunes the two LFO speeds relative to each other. Each filter frequency is then modulated
using a different LFO frequency, as determined by the Spin amount.
The Dry/Wet control adjusts the balance between the processed and dry signals. Set it to 100
percent if using Phaser in a return track.
