Mod Delay II 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 the LPF set-
ting to attenuate the high frequency content of
the feedback signal. The lower the setting, the
more high frequencies are attenuated. The max-
imum value for LPF is Off. This lets the signal
pass through without limiting the bandwidth of
the plug-in.
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.
Tempo Sync Tempo Sync provides a direct con-
nection between session tempo and plug-in pa-
rameters that support MIDI Beat Clock. This di-
rect connection lets plug-in parameters such as
delay, auto-pan, and other time-domain effects
automatically synchronize to, and follow
changes in, session tempo. For plug-ins that do
not support Tempo Sync, the original MIDI Beat
Clock window (Setup > MIDI > MIDI Beat Clock)
remains available in Pro Tools.
For more information, see “Tempo Sync” on
page 23.
Tempo
Available in some plug-ins that do not
support Tempo Sync, Tempo selects the desired
tempo in beats per minute (bpm). This setting is
independent of Pro Tools’ tempo. When a spe-
cific Duration is selected (see “Duration” be-
low), moving this control will affect the Delay
setting. Likewise, the range of both controls will
be limited to the maximum available delay with
the currently selected Duration. To enter very
short or long delays it may be necessary to dese-
lect all Duration buttons.
Meter Use this to enter either simple or com-
pound time signatures. The Meter control de-
faults to a 4/4 time signature.
The TDM versions of the Extra Long Delay
mono-to-stereo and stereo plug-in are not
supported at 96 kHz. All TDM versions of
the Extra Long Delay plug-in are not sup-
ported at 192 kHz. RTAS versions of the Ex-
tra Long Delay plug-in are fully supported
at all sample rates.
Tempo Sync is not available in plug-ins
with which it would limit functionality. For
example, for the Virus Indigo and
IndigoV40 plug-in, use the Pro Tools MIDI
Beat Clock window (Setup > MIDI > MIDI
Beat Clock). See the Pro Tools Reference
Guide for more information.
Use Event > Identify Beat or Event > Beat
Detective to determine the tempo. For more
information about Identify Beat and Beat
Detective refer to the Pro Tools Reference
Guide.
