The 9-Pin Machine Control (Deck Control) settings let you configure a Machine Control device for Serial Deck Control mode with Pro Tools. Serial Deck Control mode is available whenever Machine Control is connected using the Serial Deck Control cable. When connected for Serial Deck Control mode, Machine Control enables all Pro Tools track arming, synchronization, and Transport features, as available on your system. Serial Deck Control mode also supports 9-pin serial timecode.
When the Enable option is selected, Pro Tools is in Serial Deck Control mode.
The Port setting lets you select the 9-pin Machine Control port. The available choices depend on your platform and configuration
After you select a port, Pro Tools automatically polls the port to see what kind of machine is connected. If the machine is recognized, Pro Tools loads the corresponding
Machine Type. This includes the corresponding track layout and automatically enters the name of that machine into the Machine Track Arming window. However, if the machine is not recognized, the
“Generic 1” personality is automatically loaded.
The Preroll setting lets you specify a variable amount of machine preroll to account for the time it may take the machine to achieve servo lock. Shorter preroll values are usually better for non-linear machines. Longer preroll values are usually better for older tape transports. The Machine preroll value is added to any preroll specified in the Transport window.
