Logic Pro Modulation Delay
Modulation Delay is based on the same principles as Flanger and Chorus effects, but you
can set the delay time, allowing both chorus and flanging effects to be generated. It can
also be used without modulation to create resonator or doubling effects. The modulation
section consists of two LFOs with variable frequencies.
Although rich, combined flanging and chorus effects are possible, the Modulation Delay is
capable of producing some extreme modulation effects. These include emulations of tape
speed fluctuations and metallic, robot-like modulations of incoming signals.
Modulation Delay parameters
• Mod Intensity knob and field: Set the modulation amount.
• Time knob and field: Set the basic delay time. Set to the far left position to create
flanger effects, to the center for chorus effects, and to the far right to hear clearly
discernible delays.
• Feedback knob and field: Set the amount of effect 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 effects.
• De-Warble button: Turn on to make sure the pitch of the modulated signal
remains constant.
• Constant Mod button: Turn on to make sure the modulation width remains constant,
regardless of the modulation rate.
Note: When Constant Mod is enabled, higher modulation frequencies reduce the
modulation width.
• D-Mode button: Turn on to introduce a spatial filtering effect that resembles a
well-known vintage processor.
Note: Available only in stereo or mono->stereo instances.
