ADAT Bridge I/O38
Setup A: Synchronizing 
Pro Tools and ADAT with a 
BRC
The following section explains how to syn-
chronize Pro Tools/ADAT with a BRC. In 
this case, the BRC provides both the clock 
reference signal and the positional refer-
ence. This enables you to synchronize the 
ADAT and Pro Tools with near sample ac-
curacy. Pro Tools transport is controlled by 
the BRC. 
You can also utilize MIDI Machine Control 
in this (and all other) sync setups. MMC 
configurations are covered later in this BRC 
section. 
Synchronizing on Windows systems
When using Pro Tools on a Windows com-
puter, simply make sure your MIDI inter-
face is installed and operating correctly. In-
stead of choosing OMS or FreeMIDI device 
names, Pro Tools popup menus of MIDI 
ports simply list the available hardware 
MIDI ports of the currently installed MIDI 
Interface. 
Recording Tracks from an ADAT to 
Pro Tools Using a BRC
This setup explains how to perform a syn-
chronized ADAT-to-Pro Tools track transfer 
using a BRC. 
To transfer audio from ADAT to Pro Tools:
1 Connect the BRC and MIDI Interface to 
your system as shown in Chapter 2.
On the BRC:
2 Make sure the EXT SYNC button is off 
(unlit).
3 Enable the GEN SYNC button on the 
BRC. This enables the BRC to generate time 
code.
In OMS Setup (Macintosh Only):
4 On your computer, open the OMS Setup 
application and configure the BRC and 
your MIDI interface. (If you choose Alesis 
in the Manuf pop-up menu, and BRC in the 
Model pop-up in this dialog, the appropri-
ate settings will be configured automati-
cally). In OMS’ MIDI Device Info dialog, 
enable Sends and Receives MTC for the 
BRC. You must have an OMS device de-
fined for the BRC if you haven’t already 
done so. Click OK after configuring the 
OMS Device Info window, then connect 
the BRC to the appropriate MIDI port in 
the OMS Setup Window.
5 Save the BRC/MIDI interface configura-
tion document as your current OMS setup.
In FreeMIDI (Macintosh Only)
If you use Mark of the Unicorn’s FreeMIDI 
system, configure it for the BRC according 
to the instructions provided by Mark of the 
Unicorn.
