Machine Control
To cancel a cycle at any time, press STOP or deselect the CYCLE button or the Cycle
box. If you pressed STOP, the cycle will resume if you subsequently press PLAY.
Note that the Fr(om): and To: timecode boxes below show the start and end times of
an automated mix.

Jog Wheel

To the left of the transport control buttons is a Jog Wheel which can be used in three
different modes:
With JOG, VARISPEED and FEEDBACK not selected, and the system in Stop, the Desk
and any on-line external machines can be simultaneously moved, at any speed,
forwards or backwards. One full turn of the wheel represents 20 seconds.
With JOG selected and the system in Stop, the wheel can be used to move backwards
or forwards as above, but with much finer control. If JOG is selected and the system
put into Play, the wheel will rotate and can be grabbed at any moment to move the
Desk (computer) and slave machines back or forwards to any spot. Note that the
system drops out of Play as soon as you grab the wheel.
With VARISPEED selected and the system in Play, the wheel will varispeed the Desk,
and any machines currently selected as slaves, with a range from normal play (at the
1 /8
centre detent) up to 4 times play speed, or down to play speed, subject to the
varispeed range of the slave machine(s). The Vari: box at the top right of the
MIX-DESK display shows the current varispeed value as a percentage ranging from
12.5% up to 399.8%, where normal play speed is 100%.
FEEDBACK, if selected on its own, allows the Jog Wheel to provide a tactile frame jog
facility. As you turn the wheel, you will feel a slight indent at each frame transition.
JOG + FEEDBACK limits use of the Jog Wheel to a window defined by the current first
and last events in the Events List (see Section 4). With VARISPEED + FEEDBACK
selected, the Jog Wheel will spring back to normal play speed when released from a
positive or negative varispeed position.
Note that the above descriptions apply in full where the J Series Computer is acting as
the master to serially controlled slaves. If a tape machine is connected via the parallel
port (DCTM), only the Jog function will be available.
