Taking a Device Offline
Use the Online pop-up menu in the Transport
Master selector to take a MIDI (or Machine) de-
vice offline.
To take a device offline:
1
Click the Transport Master selector.
2
Click on the Online pop-up menu and dese-
lect the device (Machine or MIDI) by clicking on
it. Device choices depend on the current Trans-
port Master and which devices have been set up
in Pro Tools.
To bring a device back online, click and reselect
it in the Online pop-up menu.
Setting Minimum Sync Delay
Lock-up time delay is the amount of time your
system’s devices need to achieve synchroniza-
tion “lock.” This amount varies for each device.
Pro Tools lock up delay is set by entering a value
for Minimum Sync Delay in the Synchroniza-
tion window of the Peripherals dialog. The low-
est value available is 15 frames. Find the shortest
possible lock-up time that your equipment can
operate at consistently, and set this as the Mini-
mum Sync Delay. On systems utilizing Digide-
sign MachineControl, enabling the Use Serial
Time Code setting will make machines lock up
much faster. (Serial time code requires both the
SYNC peripheral and external devices to be
locked to house video reference.)
To set a Minimum Sync Delay:
1
Choose Setup > Preferences, and click Syn-
chronization.
2
Enter a number of frames in the Minimum
Sync Delay field.
3
Click OK to close the Preferences dialog.
Configuring Minimum Sync Delay for External
MMC Devices Locked to House Sync
When controlling a house-synced device from
Pro Tools through MMC, the device will first
lock to the MMC location and then align the
color framing. Within house sync code are 4
frames for ensuring color frame lock. If the min-
imum synchronization setup time is less than
the time required to achieve both location and
color frame lock, playback will begin before the
device has aligned the color frames. In this sce-
nario, you should set the Minimum Sync Delay
to be more than the time required for color
frame lock. This is not a problem with a SYNC
peripheral, which will drop out of lock until the
color frame is locked.
Deselecting a device to take it offline
The Online pop-up menu will only display
devices that have been properly set up in
Pro Tools.
