Introduction
Thank you for purchasing the MMC/9PIN+ Interface. This is a
truly unique product, integrating the world of MIDI to the world of
professional video.
This compact unit receives MIDI Machine Control (MMC) and
translates it into Sony 9 Pin / P2 protocol, which is supported by
most professional video recorders and certain audio recorders.
A hardware controller or software application that sends MMC is
connected to the MMC/9PIN+ Interface, which is connected to the
video tape recorder. Now the MIDI device can act as an
“autolocator” for the video tape recorder, sending transport, locate,
and track enable commands.
In addition, the MMC/9PIN+ Interface reads tape position and
video sync, and derives from that information both SMPTE
timecode and MIDI time code. That means that the MMC/ 9PIN+
Interface will produce a SMPTE tone resolved to video, without
the need to stripe a longitudinal timecode (LTC) track. The ability
to output both SMPTE and MTC means that you can synchronize a
sequencer or machine synchronizer to the video without the need
for striping the tape with SMPTE. The MMC/9PIN+ Interface also
features a unique “tapeless” operation mode. In this mode, the
MMC/9Pin+ Interface will generate SMPTE and MTC in response
to an MMC Play command, without any 9 Pin device connected.
The performance of the MMC/9Pin+ Interface depends largely
upon the users knowledge of the software or hardware being used
as the source of MMC, and the 9 Pin device. You will probably
need to be thoroughly familiar with this equipment before
attempting to use the MMC/9Pin+ Interface.
