Displaying and setting VTR control registers
For VTRs (a maximum of two) connected to the control panel, you can save
and recall sets of data including the start point, stop point, and start offset
point (the time from pressing the RUN button in the key frame section until
the VTR starts), in the same way as saving and recalling key frame effects.
Here the registers in which this data is saved are termed "VTR control
registers."
In the REGISTER menu, you can display the contents of VTR control
registers. You can also enter a timecode value from the numeric keypad, and
set the contents of a register.
For details of the operation, see page 9-18.
