There are four different Mod Delays, capable of
different maximum delay times:
• The Short Delay provides 1024 samples of de-
lay (23.2 milliseconds at 44.1 kHz or 21.3 ms
at 48 kHz).
• The Slap Delay provides 7186 samples of de-
lay (162 ms at 44.1 kHz or 149 ms at 48 kHz).
• The Medium Delay provides 16384 samples of
delay (371 ms at 44.1 kHz kHz or 341 ms at
48 kHz).
• The Long Delay provides 162474 samples of
delay (3.68 seconds at 44.1 kHz or 3.38 sec-
onds at 48 kHz).
Multiple Mod Delay plug-ins can be cascaded on
inserts one into another to achieve even longer
delay times. For each delay, set the Feedback to
0% and the Mix to 100% to get a single long de-
lay (the sum of all the delay times). Adjust the
various controls of each of the delays indepen-
dently to create complex delay patterns.
The Mod Delays provide a Mono In/Stereo Out
option. Choosing a delay in the Mono In/Stereo
Out format “stereoizes” the output of a mono
track. A track created in this way will then have
stereo pan faders for controlling each channel of
the stereo signal. As explained previously, any
inserts that occur on a track after a mono-to-ste-
reo insert will automatically become stereo as
well.
Mod Delay Controls
Input Controls the input volume of the delay to
prevent clipping.
Mix Controls the balance between the delayed
signal (wet) and the original signal (dry). If you
are using a delay for flanging or chorusing, you
can control the depth of the effect somewhat
with the Mix setting.
LPF (Low-Pass Filter) Controls the cutoff fre-
quency of the low-pass filter. Use this to attenu-
ate the high frequency content of the feedback
signal. The lower the setting, the more high fre-
quencies are attenuated.
Delay Sets the delay time between the original
signal and the delayed signal.
Depth Controls the depth of the modulation ap-
plied to the delayed signal.
Rate Controls the rate of modulation of the de-
layed signal.
Feedback Controls the amount of feedback ap-
plied from the output of the delay back into its
input. It also controls the number of repetitions
of the delayed signal. Negative feedback settings
give a more intense “tunnel-like” sound to
flanging effects.
The Long Delay TDM plug-in is available
only on HD-series or MIX-series systems.
Mod Delay is not supported in sessions at
sample rates greater than 48 kHz.
The Mix control is fixed at 100% in the
TDM version of the mono-to-stereo and
stereo Mod Delay Long Delay on
Pro Tools|HD-series systems.
