HDR 24/96
Because your audio content may or may not be very intelligible at these various speeds and
directions, there are indicators of the Shuttle behavior built in to the Transport controls. First the
SHUTTLE LED is lit when Shuttle is enabled. When shuttling forward, the Play LED is lit and
the FF LED blinks (indicating forward motion), and when shuttling in reverse the Play LED is lit
and the REW LED blinks (indicating reverse motion). When SHUTTLE is enabled and there is
no Transport motion, the Play LED blinks and the FF/REW LEDs are off. Because your audio content may or may not be very intelligible at these various speeds and

On the Remote 48 the Varispeed display is used to display the Transport speed whenever Shuttle
or Jog is enabled. During Shuttle, the Varispeed display reads [0.0, 0.03, 0.06, 0.12, 0.25, 0.5,
1.0, 2.0] depending on the Shuttle speed. Negative speeds are not expressed because the
Transport direction is indicated by the FF or REW LEDs. On the Remote 48 the Varispeed display is used to display the Transport speed whenever Shuttle
or Jog is enabled. During Shuttle, the Varispeed display reads [0.0, 0.03, 0.06, 0.12, 0.25, 0.5,
1.0, 2.0] depending on the Shuttle speed. Negative speeds are not expressed because the
Transport direction is indicated by the FF or REW LEDs.
Scrub Scrub
Scrub is a Tool within the GUI that for all intents and purposes works like Shuttling. You click
and drag the mouse pointer to the right by a little to play forward slowly and by a lot to play
forward fast. Or move it in the other direction for reverse. Return the mouse to the center where
you first clicked to bring it to a stop. However, Scrub and Shuttle are not identical and work
completely independent of each other. The Scrub Tool does not have any indication of speed in
the VARI display and never exceeds 1.0 times normal play speed. The Scrub Tool is used
primarily for editing and is typically combined with the I-Beam Tool for selecting. To get more
details on its operation check out the section on
editing and selection

Jog
The JOG button, like SHUTTLE enables Wheel-based off-speed transport control, but the two
mechanisms differ substantially. The Jog mode couples the movement of the Wheel directly to
the movement of the Play Head. So if the WHEEL is turned quickly then audio playback moves
along quickly. At the very moment the WHEEL changes direction
the audio playback also changes direction. In more technical terms -
the Transport plays at a speed that is directly proportional to the
clockwise rotational velocity of the WHEEL. The Jog velocity is
continuously variable between 0 and 1x the nominal playback speed.
Rotating the WHEEL clockwise causes forward transport motion,
while rotating the WHEEL counterclockwise causes reverse
transport motion.
At mid-to-high Jog speeds, the Wheel velocity is low-pass filtered to
smooth out the response of the system and produce a playback that is
reasonably free of warble. At low Jog speeds, the wheel velocity is
not filtered to allow very precise transport positioning.
Pressing the Jog button in any Transport State except Record or Record Standby enables Jog
mode. Pressing the Jog button again, or pressing any Transport button other than Record disables
Jog and Stops the Transport.
The Jog LED is lit when Jog is enabled. When Jogging forward, the Play LED is lit and the FF
LED blinks (to indicate forward motion). When Jogging in reverse the Play LED is lit and the
REW LED blinks (to indicate reverse motion). When Jog is enabled and there is no Transport
motion, the Play LED blinks and the FF/REW LEDs are off.
On the Remote 48, the Varispeed display is used to display the Transport speed whenever Jog or
Shuttle is enabled. During Jog, the display reads continuously between 0.00 and 1.00. Negative
speeds are not expressed because the Transport direction is indicated by the FF or REW LEDs.
