Chapter 10 Modulation eects 203
Modulation Delay
Modulation Delay is based on the same principles as the Flanger and Chorus eects, but you can
set the delay time, allowing both chorus and anging eects to be generated. It can also be used
without modulation to create resonator or doubling eects. The modulation section consists of
two LFOs with variable frequencies.
Although rich, combined anging and chorus eects are possible, the Modulation Delay is
capable of producing some extreme modulation eects. These include emulations of tape speed
uctuations and metallic, robot-like modulations of incoming signals.
Modulation Delay parameters
•
Feedback slider and eld: Drag to set the amount of eect signal routed back to the input.
Use a high Feedback value for strong modulations. If you want to double the signal, don’t
use Feedback. Negative values invert the phase of the feedback signal, resulting in more
chaotic eects.
•
Flanger-Chorus knob and eld: Rotate to set the basic delay time. Set to the far left position
to create anger eects, to the center for chorus eects, and to the far right to hear clearly
discernible delays.
•
De-Warble button: Turn on to make sure the pitch of the modulated signal remains constant.
•
Const(ant) Mod(ulation) button: Turn on to make sure the modulation width remains constant,
regardless of the modulation rate.
Note: When Const Mod is enabled, higher modulation frequencies reduce the modulation
width.
•
Mod(ulation) Intensity slider and eld: Drag to set the modulation amount.
•
LFO Mix slider and elds: Drag to determine the balance between the two LFOs.
•
LFO 1 and LFO 2 Rate knobs and elds: Rotate to set the modulation rate for the left and right
stereo channels. In surround instances, the center channel is assigned the middle value of the
left and right LFO Rate knobs. The other channels are assigned values between the left and
right LFO rates.
Note: The right LFO Rate knob is available only in stereo and surround instances, and it can be
set separately only if the Left Right Link button is not enabled.
•
LFO Left Right Link button: Turn on to link the modulation rates of the left and right stereo
channels. Adjustment of either Rate knob will aect the other channel in stereo instances, or
other channels in surround instances.
