MIDI Synchronization

*Refer to “Slave mode setting” in Setup mode on page 106 and “Slave mode type setting” in Setup mode on page 107, for the operation and more information.

5.Press the TIME BASE SEL key to select the MTC indication for the Time Base.

<Note on setting the MTC offset time>

“MTC offset time setting” and “MTC offset mode setting” determine at which point (ABS 0 or 001BAR/1 /00CLK) the MTC (MTC offset time) is output. Refer to the following, depending on the song start time set in your sequence software, to set the MTC output from the FD-8.

* Offset mode: ABS

When the master drive (adat) outputs the specified MTC (MTC offset time), the slave FD-8 will start the Chase-Lock operation. Remember that it will take a little time for the FD-8 to start chase-lock after the MTC is input.

Setting the MTC offset time will allow the Chase-Lock operation to start from the specified point of the master device.

For example, when the master device (adat) outputs MTC as 00H 00M 00S 00SF ~ 00H 40M 00S 00SF, if the FD-8 offset (ABS mode) is 00H 20M 00S 00SF, the FD-8 ABS time will lock from 23H 40M 00S 00SF, and if the frame rate setting is 30 frame, lock will disengage temporarily at 23H 29M 59S 29SF. Later on, it will lock again at ABS time in the vicinity of 00H 00M 03S. This is an indication that the ABS time 24H is set as access maximum time in the FD-8 and that return to “0” is not continuous. Should no overshooting of 24H occur in the ABS time, overshooting of 24H with a random MTC OFFSET can be carried out correctly.

* Offset mode: BAR

As described previously, the FD-8 uses “-002BAR/1 /00CLK” as an “ABS 0” point, there is enough time until the Chase Lock starts, and Chase Lock will be complete by the specified MTC offset time. The time length of the two bars before the Chase Lock will vary depending on the setting in the first bar for the “Time signature setting” and the “Tempo setting.” Setting the MTC offset time will also allow the Chase Lock operation to start from the specified point of the master device.

Note: After this setting, check the following items on the FD-8:

*[SLAVE] is flashing on the display: When the Chase Lock operation is complete, this indicator will light.

*[DIGITAL] lights up on the display: The units is syncing to the external digital signal.

Note: Do not connect or remove the optical cable from the DATA IN connector while Slave mode is on. Otherwise, the unit may generate noise, affecting the connected external devices.

Checking Chase Lock

1.When the master device (adat) is played, the [MTC] in the display on the slave device (FD-8) will light, the [SLAVE] will light in the display, and Chase Lock will be complete.

Check to make sure the display shows the correct MTC time.

2.When you stop the master device, the MTC transmission from the master device will be interrupted and the slave machine will also stop.

The illuminated [SLAVE] will flash.

3. While the master device is in fast forward or rewind mode, the slave machine will remain stopped.

When you start playing the master device, the slave machine will start the Chase Lock operation.

Note: The FD-8’s re-chase window is “10 frames’ fixed. That is, when the MTC of the master device and the MTC of the slave machine slip from each other by 10 frames or more, the slave machine will interpret this as being out of sync, and it will try to lock with the master device again (this is called a “re-chase” operation). During the re-chase operation, audio output will be muted. If slippage is within 10 frames, the slave machine will continue running while accepting the slippage. Since the master device supplies a digital signal to the slave machine in this system, the slave machine will not perform the re-chase operation after chase lock is complete.

* If the Chase Lock operation or control is not correct, check all connections, cables, and settings.

Recording

You may perform recording while the adat and the FD-8 are chase-lock.
