Steinberg Nuendo SyncStation Operation Manual page 12

The SyncStation always regenerates timecode at all
its outputs regardless of what the timecode source is. The
only difference when using the Virtual Master is that the
SyncStation uses its internal generator as the source of
the timecode and can respond to transport commands
from any machine control input.
9-Pin RS422
The Sony 9-Pin RS422 machine control protocol is a tried
and true standard for VTRs. The SyncStation can issue
commands to 9-Pin devices (RS422 Out) and also re-
ceive 9-Pin commands (RS422 In) from other compatible
controllers.
Many large format film mixing consoles have transport
controls built in to them for convenience. The console can
act as the master controller, issuing commands via 9-Pin
to the SyncStation to enter play or stop, for example.
MIDI Machine Control (MMC)
Transport and track arming commands can be sent and re-
ceived from the MIDI ports of the SyncStation. Third party
implementation of the MMC protocol varies with devices.
Certain MMC devices might have limited functionality.
Nuendo transport
When the Sync button is engaged on Nuendo's Transport
panel, all transport commands are sent to the "Machine
Control Output Destination" found in the Project Synchro-
nization Setup dialog.
When this is set to "Steinberg SyncStation", transport
commands will go to either the Virtual Master, RS422 Out
or MIDI Out. In most cases this should be set to the same
output as the timecode source in the SyncStation. Addi-
tionally, actions that result in the project cursor being
moved in the Project window will cause locate commands
to be issued to the SyncStation.
For example, in Edit Mode, the project cursor snaps to the
selected event's start point or sync point. This causes a "lo-
cate to..." command to be issued to the SyncStation which
will route the command to either the RS422 Out, MIDI Out
or the internal Virtual Master. That timecode source device
will then move to the timecode position causing all con-
nected devices to move to the same position.
Make sure that Nuendo's Machine Control Destina-
!
tion is the same device that generates the timecode
so that transport commands result in timecode being
generated for the entire system to chase.
If the timecode source is set to LTC, transport com-
!
mands from the MIDI and RS422 inputs will not be
passed on by the SyncStation. In a special case, it is
possible to have those transport commands issued
to the RS422 Out while using the LTC input for a
timecode source. For more information on this spe-
cial case, see the section
on page 32.
