3.10 System Example of Pro Tools
This example illustrates using the WR-DA7 in a Pro Tools system. Editing can be performed using Automation, etc. after synchronizing Pro Tools with the WR-DA7 in reference to the timecode from an ADAT (BRC). It then becomes possible to control Pro Tools, ADAT and BRC from the WR-DA7 using MMC, or to control the various parameters of Pro Tools from the WR-DA7 using the MIDI remote function of the WR-DA7.
Connecting Procedures
With the WR-DA7 powered "OFF" (Set the switches on the WR-AESS card to the AES/EBU position) insert the option cards WR-AESS (slot 1), WR-ADAT (slots 2 and 3), and WR-SMPTE into the WR- DA7, fasten them securely with the supplied screws to ensure proper grounding.
Connect the digital I/O connectors from the WR-DA7 and 888 I/O (D-sub 24-pin connector on the WR-AESS card, XLR connector on the 888 I/O. (See the Digidesign's website for the proper cable specifications.)
Connect the Macintosh computer to the MIDI interface (MIDI Timepiece A/V A/V) using the modem port.
Connect the WR-ADAT cards from the WR-DA7 to the DIGITAL IN/OUT of an ADAT using an optical cable, and press the [DIGITAL IN] switch on the front panel of each ADAT to select the digital input mode.
The BRC functions as the wordclock master. Connect WORD OUT on the BRC to WORD CLOCK IN on the WR-DA7 with a BNC cable, and terminate the WR-DA7 at 75 ohms (=ON).
Connect the WR-DA7 to port 1 MIDI IN/OUT of MIDI Timepiece A/V using a MIDI cable. The MMC and MTC functions can be used.
using a standard MIDI cable, connect the MIDI IN on the BRC to port 2 MIDI OUT of the MIDI Timepiece A/V to control the ADAT with MMC. Then connect the MIDI OUT on the BRC to port 2 MIDI IN of MIDI Timepiece A/V using a MIDI cable to operate the WR-DA7 and Pro Tools in refer- ence to the BRC's timecode.
To set MIDI connection with the WR-DA7 and MIDI Timepiece A/V using OMS start the [OMS MIDI Setup] in the Setup menu of Pro Tools and execute the simplified setup. Make sure that the MIDI Timepiece A/V, the WR-DA7 and BRC have been switched on.
1.Check the device connected to Port 1 of the MIDI Timepiece A/V on the OMS MIDI device setup screen that is displayed after the simplified setup.
2.Then, to set the MIDI messages to be used by the WR-DA7, start [OMS Studio Setup] on the Setup menu, and set [Manuf] to [Other], [Model] to [Other], and [Name] to [WR-DA7] on the Setup screen.
3.Enter a check mark at [Receives] for MIDI Timecode and [Sends] for MIDI Machine Control in order to use the MTC and MMC and also at [1] for Receive Channels to select channel 1 for MIDI reception.
Set [In 1 > Out 2 Y] and [In 2 > Out 1 Y] in the MIDI Routing window of MIDI Timepiece A/V to select the MIDI cable routing.
WR-DA7 Setup
Set the [Source Select] to [WCK IN] in the Input Set screen of D-I/O to set the WR-DA7 as slave.
To receive MTC timecode, set [MTC Port] to [MIDI} in the MIDI Setup screen.
