INSTALLING THE 896HD HARDWARE
23
SAMPLE-ACCURATE ADAT SYNC WITH NO
SYNCHRONIZER
Even if you don’t have an ADAT synchronizer, you
can achieve sample-accurate sync between ADAT-
sync compatible devices, an 896HD, and any
sample-accurate software (such as AudioDesk or
Digital Performer). Just connect the 896HD to the
end of the ADAT sync chain as shown below. You
don’t get transport control from your computer,
nor can you slave the system to SMPTE time code.
Instead, you have to play, stop, rewind and cue the
system from the transports on your recorder. If
you’re using the recorder as an additional source of
analog inputs and outputs only (not for recording),
see “Syncing optical devices” on page 25.
Figure 3-11: Sample-accurate sync between AudioDesk or Digital Performer and
one or more ADAT-sync compatible devices — without an ADAT synchronizer.
In AudioDesk or Digital Performer:
1. Make sure that Slave to External Sync is checked in the Studio menu (Basics
menu under OS 9).
2. Click the play or record button. The software will then wait for you to start
your recorder.
3. Press the Play button on the front panel of your recorder to initiate playback
or recording.
For sample-accurate sync settings in Cubase VST, see
“Sample-accurate sync to ADAT or Tascam” on page 83.

With no synchronizer, the ADAT
that is the master of the ADAT
sync chain becomes transport
master over everything, including
your audio software.
In AudioDesk or Digital Performer:
1. Choose Receive Sync in the Setup
menu (Basics menu under OS 9).
2. Choose the Sample-accurate option
shown to the left.
3. Make sure that Slave to External Sync
is checked in the Studio menu (Basics
menu under OS 9).
To set the 896HD hardware clock source for sample-accurate sync:
1. In AudioDesk or Digital Performer, choose MOTU Audio
System>Configure Hardware Driver from the Setup menu (or the
Basics menu under OS 9), or run the MOTU FireWire Audio Console.
2. Choose ADAT 9-pin from the Clock Source menu as shown to above.
3. Make sure the Sample Rate setting matches the recorder and
synchronizer.
Use this setup if you have:
✓
ADATs, Alesis hard disk recorders or any ADAT SYNC
compatible device(s).
✗ No ADAT synchronizer.
✓ Host software that supports sample-accurate sync.
This setup provides:
✓
Sample-accurate locating between all ADAT SYNC-compati-
ble devices, the 896HD and your software (AudioDesk,
Digital Performer or other sample-accurate software).
✗ No transport control of everything from the computer.
✗ No sync to SMPTE time code or other sync sources.
