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.
Multichannel Mod Delay II
The Tempo and Meter controls are linked on
multichannel versions of Mod Delay II. Each
channel has its own Duration and Groove con-
trols, but the Tempo and Meter controls are glo-
bal.
Signal Generator
The Signal Generator plug-in produces audio
test tones in a variety of frequencies, waveforms,
and amplitudes. It is particularly useful for gen-
erating reference signals with which to calibrate
Pro Tools|HD interfaces (such as the 96 I/O or
192 I/O) and other elements of your studio.
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
version of Mod Delay II that has a longer
delay time (for example, switch from Me-
dium Delay to Long Delay).

Refer to the Pro Tools|HD Getting Started
Guide for instructions on using Signal Gen-
erator to calibrate the 96 I/O, or 192 I/O
audio interfaces, as well as older audio in-
terfaces.
Signal Generator plug-in
The TDM Signal Generator produces a tone
as soon as it is inserted on a track. To mute
the Signal Generator, use the Bypass button.
When using the RTAS version of Signal
Generator, start playback to generate.
