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” below),
moving this control will affect the Delay setting.
Likewise, the range of both controls will be lim-
ited to the maximum available delay with the
currently selected Duration. To enter very short
or long delays it may be necessary to deselect 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.
Duration Specifies a desired delay from a musical
perspective. Enter the desired delay by selecting
appropriate note value (whole note, half note,
quarter note, eight note, or sixteenth note). Se-
lect the Dot or Triplet modifier buttons to dot
the selected note value or make it a triplet. For
example, selecting a quarter note and then se-
lecting the dot indicates a dotted quarter note,
and selecting an eighth note and then selecting
the triplet indicates a triplet eight note.
Groove Provides fine adjustment of the delay in
percentages of a 1:4 subdivision of the beat. It
can be used to add “swing” by slightly offsetting
the delay from the precise beat of the track.
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.
Tempo, Meter, Duration, and Groove controls
It is not possible to exceed the maximum
delay length for a particular version of Mod
Delay II. Consequently, when adjusting any
of the tempo controls (Tempo, Meter, Dura-
tion, and Groove) you may not be able to
adjust the control across its full range. If
you encounter this behavior, switch to a ver-
sion of Mod Delay II that has a longer delay
time (for example, switch from Medium De-
lay to Long Delay).
