Since connecting the Digital Timepiece to my MIDI
interface, I've been encountering SysEx errors in
my editor/librarian.
The Digital Timepiece in its default state will “poll”
for MMC devices. Because of this, the Digital
Timepiece will transmit SysEx. If this SysEx is
merged with SysEx that the MIDI device or editor/
librarian is expecting, it may cause SysEx errors. To
correct the problem, you can temporarily turn off
the Digital Timepiece, or you can turn off “Enable
automatic device detection” in the Device Settings
and Routing window's Port Setting for all devices.
Doing so disables the Digital Timepiece's polling.
Most, but not all of my LRC buttons work.
Review the LRC section in the user's manual, and
compare values in the LRC table with the LRC
values generated by your LRC (use a video monitor
if necessary to display the values). If values do not
match, use the calibration procedure to “fine tune”
your Digital Timepiece for your LRC.
When I change time base mode to ADAT, the ADAT
in my console software appears with an “X”
through it, and a Purge button displays. Why?
Neither an ADAT nor DA-88 can simultaneously
be a slave and master at the same time. In ADAT
master mode, you are essentially controlling the
ADAT from its front panel, and you lose the ability
to control device-specific functions from the
software console.
Why does my DA-88 display “Warning E CLOC”
on the front panel in some time base settings?
This is a warning that the DA-88 displays if there is
no detection of clock (ex. ADAT time base setting).
In most cases, once the time base master goes into
play and clock is generated to the DA-88, the error
goes away.
When I slave the DTP to my analog multitrack (or
other analog SMPTE source), sometimes when I
stop and start the transports, it takes the DTP
much longer to lock up. Why?
When the DTP locks to LTC, it tracks the speed of
the incoming time code so that it can be ready to
freewheel and jam-sync at the same speed as the
time code. Some analog tape decks (and other
analog video and audio recording equipment),
especially older ones, leave their playback head
engaged as the tape transport starts and stops. In
addition, they don’t automatically mute when the
transport is starting up or stopping. The result is
that when you stop the deck, the LTC slows down
drastically as the transport comes to a stop. When
the DTP tracks this drastic slow-down in the time
code, its phase lock engine adjusts to the drastically
slower speed. When you start feeding it normal
time code again, it has to spin back up to a normal
speed, which takes much longer than usual because
of the size of the change. So initially, you might
experience a lock-up time of approximately 5-10
seconds. If you stop the deck then hit play again,
the DTP might take 20 seconds to a minute to lock.
If you then power-cycle the DTP, the lock up time
the next time you hit play will be back to the
normal 5-10 seconds.
