The settings and functions are:
Consist of Rewind, Fast Forward, Play, Stop, Record, Locate, GoTo and
Loop buttons. For added convenience, Play, Stop, Record, GoTo and Loop
are also featured on the control surface keyboard. The Machine Control
keys can be configured in the Option/TC-Reader/Generator Menu for:
• None: Both Machine Control key/button sets are disabled.
• 9-pin serial control: Both Machine Control key/button sets control the
one 9-pin port.
This setting may be used to serially control a single transport, or to
control the optional multi-machine Motion Controller system.
• Generator Control: Both Machine Control key/button sets control the
TC2 or TC3 Timecode Generator. This setting is used for pre-striping
tapes with timecode data, or to control machine transports in TC chase
mode.
Loc: The connected 9-pin machine will locate to the selected From time-
code address.
The Loop, Rehearse, and Drop-In (Auto Rec) selection operates in con-
junction with the Loop button:
• Loop: The machine will play in an endless loop, starting with the
From timecode setting, and ending with the To timecode value.
• Rehearse: The machine will play in an endless loop, starting with the
(From – Pre-roll) timecode setting, and ending with the (To + Post-
roll) timecode value. In addition, any machine tracks set to Ready will
go into a simulated Record function, starting with the From timecode
setting, and ending with the To timecode value.
• Auto Rec: The machine will play in an endless Loop, starting with the
(From – Pre-roll) timecode setting, and ending with the (To + Post-
roll) TC value. In addition, any machine track set to Ready will enter
Record mode, starting with the from, and ending with the to TC value.
(A value set in the Option/TC-Reader/Generator Menu). This action al-
lows the operator to enter a Pre-roll time in timecode format. The con-
trolled audio or video machine will be parked before the actual drop-in
point given by the value "x" = Pre-roll time, and then synchronized in Play
mode (usually, Pre-roll is set to values from 3 to 5 s).
(A value set in the Option/TC-Reader/Generator Menu). This action al-
lows the operator to enter a Post-roll time in timecode format. The con-
trolled audio or video machine will be kept in synchronized Play mode af-
ter the actual drop-out point for the value "y" = Post-roll time (usually,
post-roll is set to about one second).
This action allows the user to enter a start-timecode address (From) and an
end-timecode address (To) for the Locate, Loop, and GoTo functions. The
timecode values can be entered manually, using the control surface key-
board. You can also select any of the existing Cue Points by clicking on
the Cue button.
Note: Rehearse and Auto-Rec modes are depending on the connected machine.
The feature has been tested with common Sony VCR machines. Studer
cannot guarantee proper function with all 9-pin machines being currently
on the market. However, some options exist for system administrator use
to adapt the 9-pin behavior of the D950/Vista to some machines (refer to
the Service Manual).
