Chapter 35: Working with Synchronization 563
The Online button flashes while Pro Tools waits
for a SMPTE frame to trigger playback. When
time code is received, playback begins and the
Online button becomes highlighted. The Loca-
tion Indicators in the Edit window toolbar, and
the Incoming Time field in the Session Setup
window display the incoming time code (in
Pro Tools 5.x, this field is labelled Current
Time).
To take Pro Tools offline:
■ Deselect Operations > Online.
– or –
■ Deselect the Online button in the Transport
window.
Recording Online
The Operation page of the Preferences dialog
(Setups > Preferences) contains two options that
affect how Pro Tools initiates recording when
online.
Record Online At Insertion/Selection Makes on-
line recording begin wherever you have placed
the insertion point in a track. Recording then
continues until Pro Tools stops receiving time
code. If you make a selection in a track,
Pro Tools will record online only for the length
of the selection.
Record Online at Time Code (or ADAT)
Lock Makes online recording begin as soon as
Pro Tools receives and locks to time code or
ADAT sync. In this case, you don’t need to make
an insertion or selection in a track to designate a
start point.
Generating Time Code
Using SYNC I/O, Pro Tools can generate SMPTE
and MIDI Time Code (MTC). You can then
make Pro Tools a master synchronization source
with other devices slaved to it.
SYNC I/O cannot generate 30 fps, 24 fps, or
23.976 fps time code while locked to video
input or video reference
The SYNC I/O cannot generate 30 fps, 24 fps, or
23.976 fps time code while it is locked to a video
clock signal. If you set Pro Tools to generate
30 fps time code while the SYNC I/O is locked to
a video clock signal, the SYNC I/O will actually
generate at the NTSC color standard 29.97 fps.
Pro Tools can generate time code at non-NTSC
frame rates if you use the internal clock or exter-
nal word clock on the SYNC I/O as a synchroni-
zation source.
To generate time code using SYNC I/O:
1 Connect the SYNC I/O LTC Out to the SMPTE
in connector on the devices you are slaving. If
you are slaving a device that recognizes MTC,
connect the MTC OUT connector of the
SYNC I/O to the MIDI IN connector of the
slaved device (MIDI Interface or other).
2 Make sure your SYNC I/O is powered on.
3 Launch Pro Tools, and make sure you have al-
ready enabled the SYNC I/O in the Synchroniza-
tion page of the Peripherals dialog. See the SYNC
I/O Guide for more information.
4 Choose Windows > Show Session Setup, and
choose the appropriate frame rate from the
Timecode Rate selector (called the Frame Rate
selector in Pro Tools 6.2 and lower).
5 Select SYNC I/O from the Generate selector in
the Time Code Settings section of the Session
Setup window.
