MOTU 828mkII User Manual page 87

Follow the instructions in your Cubase or Nuendo
manual for slaving them to MIDI Time Code
(MTC). To ensure that your audio tracks don't drift
out of sync with your MIDI tracks — or time code,
use a hardware synchronizer like the MIDI
Timepiece AV or Digital Timepiece to resolve the
828mkII hardware as well, as explained in "Syncing
to video and/or SMPTE time code using a
synchronizer" on page 28. A digital audio
synchronizer is required for drift-free SMPTE/
MIDI time code sync. Make sure the Clock Source
setting in the MOTU FireWire Audio Console
window has the appropriate setting for locking the
828mkII to the synchronizer. For example, in
Figure 3-15 on page 28, word clock is being used to
resolve an 828mkII interface, so the Clock Source
setting is Word Clock In.
☛
If you have an ADAT sync or a Tascam sync
compatible device, don't use SMPTE time code.
Instead, use sample-accurate sync as described in
the next section.
Sample-accurate sync to ADAT or Tascam
Cubase and Nuendo, along with the 828mkII and
its ASIO 2 driver, provide you with sample-
accurate transfers with ADATs, Alesis recorders
and any other devices that support standard ADAT
sample address (ADAT Sync).
Similarly, with the help of a MOTU Digital
Timepiece universal A/V synchronizer, Cubase (or
Nuendo) and an 828mkII can perform sample-
accurate transfers with Tascam digital recorders.
A sample-accurate transfer is one in which the
original location of the audio is preserved in the
transfer, down to the sample.
For details on how to connect your hardware for
sample-accurate sync, see "Sample-accurate sync"
on page 24. Then, set up Cubase as follows:
C U B A S E , N U E N D O A N D O S 9 A S I O S O F T W A R E
☛
Before you begin, in Cubase's MIDI System
Setup window, set OMS compatibility to No OMS.
Cubase does not appear to be able to achieve
sample-accurate sync when running under OMS.
1 Choose ADAT 9-pin as the Audio Clock Source
setting. In Cubase VST, this setting is in the Audio
System Setup window (Audio menu). In Nuendo,
this setting is in the Device Setup window (Options
menu).
2 Go to Cubase or Nuendo's Synchronization
window, as shown below:

Figure 11-8: Setting up sample-accurate sync via ASIO 2.
3 If you are not using an MMC-compatible
synchronizer (such as a MOTU MIDI
Timepiece AV, Digital Timepiece or Alesis BRC),
choose the settings shown above in Figure 11-8
that applies to you. In this scenario, transport
control is handled by the ADAT (or other sample-
accurate sync source).
