ADAT Bridge I/O36
11 In Pro Tools, choose Peripherals from
the Setups menu. From the Device pop-up,
choose Generic MTC Reader. From the Port
pop-up, select the OMS port location that
you defined in OMS Setup (modem or
printer). Click OK to close this dialog.
OMS should now be configured for com-
munication between your peripheral and
Pro Tools.
▲ Pro Tools requires that you disable (un-
check) the “Use Apple Serial DMA driver when
available” preference in OMS Setup. If you do
not disable this option, problems may occur
with MIDI and synchronization functions.
To disable Serial DMA in OMS:
1 Choose Preferences from OMS Studio
Setup’s Edit menu.
2 Deselect the Use Serial DMA option.
3 Click OK to close the Preferences win-
dow.
Transferring Audio
Between ADAT and
Pro Tools (Synchronized)
A more powerful way to transfer tracks be-
tween Pro Tools and ADAT is to do it with
both systems synchronized. With the sys-
tems in sync, you can record tracks into
Pro Tools to edit and process them as
needed, then record them back into place
on the ADAT.
This section provides a few of the most
commonly used configurations for syn-
chronizing Pro Tools and ADAT.
Choosing the Master Clock Source
A synchronized system requires a master
clock reference signal so that all connected
devices will run at the same speed, slaved
to that clock. Possible sources of the master
clock reference include:
• Pro Tools
• ADAT
• A BRC
• A blackburst generator
• A third-party synchronization peripheral
(MTP AV, DTP, or 64XTC)
• Any digital device that generates an
AES/EBU, S/PDIF, or word clock signal
Which device you choose will depend on
the equipment you are using with your sys-
tem. As a general rule, you should choose
the most stable clock source possible.
Whatever device you use as your master
clock reference, you must configure
Pro Tools and the ADAT accordingly.
