Yamaha AW2400 Owner's Manual page 199

E DEVICE NO. box
Specifies the MMC device number (1–127) that the
AW2400 will receive.
NOTE
• The MMC device number is an identifying number used to distin-
guish devices that transmit and receive MMC commands. When
using MMC, the AW2400 and the external MIDI device must be set
to the same MMC device number.
• When transmitting MMC data from the AW2400, the MMC device
number is always set to "128" (allowing control of all MMC-com-
patible devices).
F MTC field
Specifies how the AW2400 operates when synchronized
with an external MIDI device using MTC (MIDI Time
Code).
G MTC MASTER button
When this button is on the AW2400 functions as MTC
master. Turn this button on when you want external equip-
ment to synchronize to the AW2400.
H MTC SLAVE button
When this button is turned on the AW2400 functions as
MTC slave, and will follow MTC received via the MIDI
IN connector (or USB connector or digital I/O card input
port). Turn this button on when you want to synchronize
two AW2400 units, or synchronize the AW2400 to an
external device that can only function in MTC master
mode.
I SYNC AVERAGE box
Select one of the following to specify how closely the
AW2400 will follow the incoming MTC data when func-
tioning as an MTC slave.
• 0 ............. The AW2400 will synchronize to the incoming
MTC data with the highest precision. If the
incoming MTC has significant instability, syn-
chronization may be interrupted or become
unreliable with this setting.
• 1 ............. This setting provides more tolerance to MTC
instability than the OFF setting.
• 2 ............. This setting allows the maximum tolerance.
Use this setting if the MTC master is an exter-
nal MIDI device that has significant instability.
HINT
• If the accuracy of the incoming MTC becomes unstable when the
AW2400 is functioning as an MTC slave and is synchronized to an
external MIDI device, the AW2400 will make slight adjustments in
playback pitch in an attempt to maintain synchronization. The
SYNC AVERAGE parameter specifies the range of MTC variance
that will be tolerated.
MIDI Synchronization Message Setup
J OFFSET
When using the AW2400 as an MTC slave, this parameter
shifts the absolute time of the AW2400 forward or back-
ward relative to the incoming MTC. The range is
-24:00:00:00.00 to +24:00:00:00.00.

HINT
• The OFFSET setting has no effect on MTC output via the MIDI
OUT/THRU connector (or USB connector or digital I/O card output
port).
K SYNC OUT field
Selects the type of MIDI message to be used for synchro-
nization.
• OFF button ........Engage this button (it will appear
inverted) to disable transmission of
MIDI synchronization messages.
• MTC button .......When this button is ON MTC will be
transmitted while the recorder is run-
ning.
• MIDI CLOCK Button
...............When this button is ON the MIDI clock
will be transmitted while the recorder
is running. Also, appropriate START,
STOP, CONTINUE and SONG POSI-
TION messages will be transmitted
when the transport is operated.
HINT
• MIDI clock operation is based on the tempo specified in the Tempo
Map (refer to page 175 for Tempo Map setup details).
