Setting the Time Base
Automix requires an external timecode source. The 03D does not generate timecode
internally. Automix can be used with MTC (MIDI Timecode) or MIDI Clock. Time-
code signals are input using the MIDI IN or TO HOST connection. See MIDI Connec-
tors & TO HOST on page 232 for more information. The 03D’s time base settings must
be set to match the incoming timecode signal. Time base settings are made in the TIME
BASE section of the Main automix page.

1. Use the [AUTOMIX] button to locate the Main page.
2. Use the cursor buttons to select a time base.
The following time bases are available:
ND
—MTC 29.97 frame/sec non-drop or 30 frame/sec non-drop
DF
—MTC 29.97 frame/sec drop or 30 frame/sec drop
25
—MTC 25 frame/sec
24
—MTC 24 frame/sec
MIDI CLK
—MIDI Clock
3. Press the [ENTER] button to activate the selected time base.
The 03D supports the following MIDI messages: Timing Clock (F8H), Start (FAH),
Continue (FBH), Stop (FCH), Song Position Pointers (F3H, **H, **H), and MTC
Quarter Frame Messages (F1H, **H).
Continue (FBH), Stop (FCH), Song Position Pointers (F3H, **H, **H), and MTC
Quarter Frame Messages (F1H, **H).
In Auto Play mode, automix starts automatically when MTC or a MIDI Start or Con-
tinue message is received. Likewise, automix stops automatically when the MTC stops
or a MIDI Stop message is received.
tinue message is received. Likewise, automix stops automatically when the MTC stops
or a MIDI Stop message is received.
The maximum recording time for the ND and DF time bases is 19 hours. For the 25 and
24 time bases, it’s 23 hours. For MIDI Clock, it’s two million MIDI Clocks.
24 time bases, it’s 23 hours. For MIDI Clock, it’s two million MIDI Clocks.
When a timecode of a different frame rate to that set for the current automix is received,
a warning message appears. If the frame rate is within
a warning message appears. If the frame rate is within
±
2 frames, however, the automix
will synchronize to it but will be offset by the difference in rates.
Note: The time base must be set before recording events in a new automix. Once events
have been recorded, the time base settings cannot be changed.
