140 Chapter 9 Modulation
Phaser
The Phaser effect combines the original signal with a copy that is slightly out of phase
with the original. This means that the amplitude of the two signals reach their highest
and lowest points at slightly different times. The timing differences between the two
signals is modulated by two independent LFOs.
In addition, the Phaser includes a filter circuit and a built-in envelope follower, which
tracks any volume changes in the input signal, generating a dynamic control signal.
 Filter button: Click to activate the filter section, which processes the feedback signal
of the Pitch Shifter.
 LP and HP knobs and fields: Use these to set the cutoff frequency of the filter section’s
highpass and lowpass filters.
 Feedback slider and field: Determines the amount of the effect signal that is routed
back into the input of the effect.
 Ceiling and Floor slider and fields: Use the individual slider handles to determine the
frequency range that will be affected by the LFO modulations.
 Order slider and field: Allows you to choose between different phaser algorithms. The
more orders a phaser has, the heavier the effect.
 Env Follow slider and field (Sweep section): Determines how much the frequency
range (as set with the Ceiling and Floor controls) is modulated by the level of the
input signal.
 LFO 1 and LFO 2 Rate knobs and fields: Use to set the speed for each LFO
independently.
 LFO Mix slider and fields: Determines the balance between the two LFOs.
 Env Follow slider and field (LFO section): Use this to set how much the speed of LFO 1
is modulated by the level of the input signal.
 Phase knob and field (only available in stereo and surround instances): Controls the
phase relationship between the individual channel modulations. At 0°, the extreme
values of the modulation are achieved simultaneously for all channels. 180° or –180°
is equal to the greatest possible distance between the modulation phases of the
channels.
