Chapter 10 Modulation eects 204
•
LFO Phase knob and eld: Rotate to control the phase relationship between individual channel
modulations. Available only in stereo and surround instances.
•
At 0°, the extreme values of the modulation are achieved simultaneously for all channels.
•
At 180° or −180°, you achieve the greatest possible distance between the modulation phases
of the channels.
Note: The LFO Phase parameter is available only if the LFO Left Right Link button is active.
•
Distribution pop-up menu: Choose how phase osets between individual channels are
distributed in the surround eld: “circular,” “left↔right,” “front↔rear,” “random,” or “new random.”
Available only in surround instances.
Note: When you load a setting that uses the “random” option, the saved phase oset value
is recalled. If you want to randomize the phase setting again, choose “new random” from the
Distribution pop-up menu.
•
Volume Mod(ulation) slider and eld: Drag to determine the impact of LFO modulation on the
amplitude of the eect signal.
•
Output Mix slider and eld: Drag to determine the balance between dry and wet signals.
•
All Pass button (Extended Parameters area): Turn on to introduce an additional allpass lter into
the signal path. An allpass lter shifts the phase angle of a signal, inuencing its stereo image.
•
All Pass Left and All Pass Right sliders and elds (Extended Parameters area): Drag to determine
the frequency at which the phase shift crosses 90°—the halfway point of the total 180°—for
each of the stereo channels. In surround instances, the other channels are automatically
assigned values that fall between the two settings.
