Serial Transport
This mode allows the MMP-16 to control an external audio or video transport connected to the 9-pin
serial Transport connector. Video and audio decks using the P2 protocol can be controlled (including
models from Accom, Alesis, Ampex, Fostex, JVC, Otari, Panasonic, Sony, and TASCAM). When in
Serial Tran mode, the MM series unit will output transport commands to external serial devices through
the 9-pin serial Transport output using Sony P-2 protocol. The unit will then lock to the external serial
device via linear timecode coming from the device through the MM unit’s timecode input (not through
serial timecode).
Editor
Using the Editor connector (and Sony P2 protocol) a video editor or other non-Lynx synchronizer can
control the MMP-16 transport functions when the MMP-16 Control Mode is set to Editor. When in Editor
mode, the MM series unit will respond to transport and track arming commands coming in to the 9-pin
serial Editor port. This setting is typically used with traditional video edit controllers.
Varispeed
Varispeed mode allows for setting playback speed within a range of 87.5% to 112.5% of nominal play
speed. This range varies according to the sample rate selected. Varispeed varies the playback frequency as
well as the digital sample clock on the digital output.
Serial Editor Port Details
There are a number of important details to note about the Serial Editor port as noted below.
Record Ready Tallies
Record ready tallies issued over the 9-pin serial Editor port now include tracks armed at the MMR-8 front
panel or MM-RC, and not just those tracks armed by serial command. This allows an external Serial
device to know when a track has been armed for recording, regardless of the source of the track arm
command.
Sony P2 Chase and Offset Commands
Sony P-2 protocol Chase and Offset commands are accepted by the MMR/MMP. Setup Menu 404 allows
for setting the chase source to either Timecode, Biphase, or Disabled.
Serial Editor Port Active When Not ONLINE
The MMR/MMP unit will follow transport, track arm, and record commands given on the 9-pin serial
Editor port even when the unit is not ONLINE.
Automatic ONLINE
The MMR/MMP unit will automatically be placed in the ONLINE state when placed in Chase via the
serial 9-pin Editor port.
Local Machine Response to Serial Record Commands
Serial record arm and punch in/out commands are honored locally on each machine, regardless of whether
it is acting as an MMR Bus slave or master machine. These commands are not propagated across the
