Choose Receive Sync from the Basics menu and
choose the Sample accurate option. Then make
sure that the Slave to External Sync command in the
Basic menu is checked. Make sure the Clock Source
setting in the MOTU PCI Audio Console window
is set to PCI-424: SMPTE or PCI-424: Video. Also,
make sure that you’ve specified the SMPTE time
code input (if necessary) in the MOTU SMPTE
Console applet, as shown in Figure 3-23 on page 41
or Figure 3-24 on page 42.
Resolving to video and/or time code with a
dedicated synchronizer
To resolve your Digital Performer/PCI-424 system
to video and/or SMPTE time code using an
additional synchronization device, use the setup
shown in “Syncing to video and/or SMPTE time
code using a synchronizer” on page 43.
Choose Receive Sync from the Basics menu and
choose the MTC (MIDI Time Code) option. Then
make sure that the Slave to External Sync command
in the Basic menu is checked. 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 PCI-424 hardware
as well, as shown in Figure 3-25 on page 43. A
digital audio synchronizer is required for drift-free
SMPTE/MIDI time code sync. Make sure the Clock
Source setting in the MOTU PCI Audio Console
window has the appropriate setting for locking the
PCI-424 system to the synchronizer. For example,
in Figure 3-25 on page 43, word clock is being used
to resolve a 2408mk3, so the Clock Source setting is
2408mk3: 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
Together, Digital Performer and the PCI-424
system provide you with sample-accurate transfers
with ADATs, Alesis recorders, or any other devices
that support standard ADAT sample address
(ADAT Sync).
Similarly, with the help of a MOTU Digital
Timepiece, Digital Performer and a 2408mk3
system 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 set up sample-accurate sync,
see “Sample-accurate sync” on page 37. Be sure to
choose the Sample Accurate Sync option in Digital
Performer’s Receive Sync dialog (Basics menu), and
make sure that the Slave to External Sync command
is checked in the Basic menu, too.
To control the transports of everything together
from Digital Performer, see the next section.
MIDI MACHINE CONTROL (MMC)
If you have ADATs and a MMC-compatible ADAT
synchronizer like the MIDI Timepiece AV and
Digital Timepiece, you can control everything
from your computer screen with Digital
Performer’s transport controls and cueing features
(like Markers, the playback wiper, etc.)
Similarly, if you have Tascam recorders and a
MOTU Digital Timepiece (or other MMC-
compatible Tascam synchronizer), can control all
of your Tascam decks (in ABS time) in a similar
fashion from Digital Performer.
See the MIDI Machine Control chapter in your
MIDI Timepiece AV or Digital Timepiece manual
for details on how to set this up.
