SYNCING TO A DA-88/98 TIME CODE TRACK
If you have a Tascam DA-88 equipped with an
SY-88 card, or a DA-98, and you would like to slave
your entire system to its time code track, the
DA-88/98 serves as the SMPTE time code master,
while the PCI-424 system serves as the word clock
master over the DA-88/98. In this setup, you feed
MIDI Time Code (MTC) to the computer from the
DA-88/98. To establish word clock phase-lock
between the DA-88/98, you can either feed word
clock from a MOTU PCI audio interface to the
DA-88/98 or the opposite (feed word clock from
the DA-88/98 to the MOTU interface). Or you can
slave them both to a third word clock master, such
as a MOTU Digital Timepiece.

With this setup, in the MOTU PCI Audio Console
window, you can choose any clock source, since the
DA-88/98 is slaving to the 2408mk3. The DA-88/98
will slave to the 2408mk3, regardless of what the
PCI-424 system is slaving to.
Figure 4-27: This setup shows how you can slave your audio software to the time code track on a Tascam DA-88/98 tape. This is the simplest
case, with no other devices involved. But regardless of your setup, make sure that the DA-88 and PCI-424 system share the same audio clock.
Any MOTU PCI interface
Use this setup if you have:
✓
Tascam DA-88 with an SY-88 sync card, a Tascam
DA-98 or any other Tascam deck with a time code track.
This setup provides:
✗
No sample-accurate locating.
✗
No transport control from the computer (transport
control is from the DA-88/98 itself).
✓ Timing accuracy that is at least as good as MIDI time
code (quarter-frame)— and maybe even tighter.
✓ Continuous sync to SMPTE time code on the time code
track of the tape in your DA-88/98.
