Pro Tools Reference Guide 806
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 Edit
Selection indicators in the Edit window, and the
Incoming Time field in the Session Setup win-
dow display the incoming time code.
To take Pro Tools offline, do one of the following:
■
Deselect Options > Transport Online.
– or –
■
Deselect the Online button in the Transport
window.
Recording Online
The Operation Preferences page contains two
options that affect how Pro Tools initiates re-
cording when online.
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 do not need to
make an insertion or selection in a track to des-
ignate a start point.
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.
Generating Time Code
Using a SYNC peripheral, 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.
A SYNC peripheral cannot generate 30 fps,
24 fps, or 23.976 fps time code while locked to
video input or video reference
A SYNC peripheral 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 pe-
ripheral is locked to a video clock signal, the
SYNC peripheral 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 external word
clock on the SYNC peripheral as a synchroniza-
tion source.
To generate time code using a SYNC peripheral:
1
Connect the SYNC peripheral LTC Out to the
SMPTE in connector on the devices you are slav-
ing. If you are slaving a device that recognizes
MTC, connect the MTC OUT connector of the
SYNC peripheral to the MIDI IN connector of
the slaved device.
2
Make sure your SYNC peripheral is powered
on.
3
In Pro Tools, choose Setup > Peripherals and
click Synchronization.
4
In the Digidesign Synchronization Device sec-
tion of the Synchronization page, select Enable
SYNC Peripheral.
5
Click OK to close the Peripherals dialog.
