The Wheel and MMC Commands
The wheel has two distinct modes of operation, Jog and
Shuttle. The wheel defaults to Jog mode on power up.
To change from Jog to Shuttle mode, press the Jog button to
turn the LED off.
MMC Jog Mode
In Jog mode, playback speed and direction is proportional to
the speed and direction that the wheel is rotated.
Rotate the wheel clockwise for forward playback.
Rotate the wheel counter clockwise for reverse playback.
In jog mode, continuously rotating the wheel results in 1X play
speed, either forward or backward.
To stop the tape, simply stop turning the wheel.
Though there is no "Jog" command in the MMC specification,
the MCS
2
has the unique ability to produce the same effect as
Jog. (For the details about how this is done, see the MIDI
Implementation later in this manual.)
Shuttle Mode
In Shuttle mode, playback speed is related to the extent of
rotation away from the starting position of the wheel.
Rotate the wheel clockwise for forward shuttle.
Rotate the wheel counter clockwise for reverse shuttle.
In shuttle mode, one does not continuously rotate the wheel.
The machine continues to shuttle until the wheel is returned to
its starting position. Alternately, simply press Stop.
The current position of the wheel becomes its new starting
position for the next shuttle operation.
