Chapter 3: Remote Operation 17
With a multi-port MIDI interface, every unit
must be daisy-chained from a single port on
your MIDI interface. Connect the MIDI Out port
of the MIDI interface to the MIDI In port of the
first PRE, then connect the MIDI Out port of the
first PRE to the MIDI In port of the second PRE,
and so on. Make sure to connect the MIDI Out
port of the last PRE to the MIDI In port of the
MIDI interface.
Powering Up Pro Tools System
In order for Pro Tools to communicate properly
with audio interfaces and other peripherals, it is
important that you start up and shut down your
system in the following order:
Power up your system in this order:
1 Turn on your Pro Tools hard drives. Wait ap-
proximately ten seconds for them to spin up to
speed.
2 Turn on PRE.
3 Turn on synchronization or other MIDI pe-
ripherals or interfaces.
4 Turn on your Pro Tools audio interfaces.
5 Turn on your computer.
6 Turn on your speakers or other monitor sys-
tem last.
Power down your system in this order:
1 Turn off your speakers or other monitor sys-
tem.
2 Quit Pro Tools.
3 Shut down the computer.
4 Power off your audio interfaces.
5 Turn off PRE
6 Turn off any synchronization, MIDI, or other
peripherals or interfaces.
7 Turn off your drives.
Configuring OMS for Your PRE
Before using a PRE with Pro Tools, you must first
configure it as an OMS device.
The following are basic instructions for config-
uring your PRE in OMS. If you are installing
OMS for the first time, refer to your Getting
Started with HD Guide. If you are not familiar
with OMS, OMS devices, or how to configure
OMS Setup, refer to the OMS documentation in-
cluded on the Pro Tools CD-ROM.
To configure your PRE in OMS:
1 Launch OMS Setup from the Finder or from
within Pro Tools (choose Setups > OMS Setups).
2 If you are configuring PRE and a MIDI inter-
face, choose File > New Studio Setup. If you are
configuring only PRE, continue to the next step.
3 Click on your MIDI interface, then choose
Studio > New Device. The MIDI Device Info dia-
log opens.
With multiple PREs, it is easier to keep
track of each unit in Pro Tools by setting
MIDI channels in ascending order, in rela-
tion to the physical position of the PREs (for
example, in the order they are stacked in a
rack).
