Transport Controls
Genex Audio Inc Page 7
Play
Press the Play button to start forward play at x1 speed. The upper alphanumeric display shows the
current time-code.
Stop
Press the Stop button to cancel the current transport mode.
Fast Forward and Fast Reverse
The operator can use the Fast Forward and Fast Reverse buttons to emulate the locate functions of
a tape deck. Repeated pressing doubles the search speed up to a maximum x32 in either direction.
Fast Forward automatically stops at 24:00:00:00 and Fast Reverse automatically stops at
00:00:00:00. Pressing Play from either Fast Reverse or Fast Forward instantly puts the unit into Play.
Pressing Stop instantly stops the unit. Audio output is muted during Fast Forward and Fast Reverse.
The Fast Forward and Fast Reverse buttons are not disabled when in record; the unit will drop out of
record and start spooling.
±10 Seconds
Press the +10 button to advance the unit 10 seconds in the forward direction. Press the -10 button to
retard the playback position by 10 seconds. If the unit is stopped when either button is pressed the
unit is parked at the new timecode position. If the unit is in play when the buttons are pressed,
playback continues at the new timecode. The +10 and -10 buttons are disabled when in record.
Previous and Next
The Previous button moves the transport to the first cue point prior to the current location. The Next
button selects the next cue point ahead of the current location. If the unit is in Play when either button
is pressed, playback continues from the new location, otherwise the unit is parked at the new location.
The Next and Previous buttons are disabled when in record.

Jog
Press the Jog button to put the unit into Jog mode. The Jog LED will light to confirm the mode. In Jog
mode the Rotary Wheel can be used to move audio backwards and forwards in the same way as
moving a piece of tape across a magnetic head. The speed of playback is dependant on the speed of
the Rotary Wheel. To cancel Jog mode press any of the following buttons, Play, Stop, Fast
Forward, Fast Reverse, Jog, Shuttle, Varispeed, or perform a Locate operation. The Jog mode will
not currently operate in DSD mode.
Shuttle
Press the Shuttle button to enable Fast Forward or Fast Reverse in preset increments. The exact
speed is selected using the Rotary Wheel. The following options are available.
0 ±1.0 ±2.0 ±3.0 ±4.0 ±5.0 ±6.0 ±7.0 ±8.0 ±9.0
10.0 ±11.0 ±12.0 ±13.0 ±14.0 ±51.0 ±16.0 ±17.0 ±18.0 ±19.0
20.0 ±25.0 ±30.0 ±35.0 ±40.0 ±45.0 ±50.0
Turn the Rotary Wheel clockwise to select forward motion. Turn the Rotary Wheel counter clockwise
to select reverse motion. Playback automatically stops at 24:00:00:00 in the forward direction and
00:00:00:00 in the reverse direction. To cancel Shuttle mode press the Stop or Shuttle buttons. At
present, no audio is heard during shuttle.
Varispeed
The Varispeed range of the GX9000 is +/-24%. The rate can be adjusted in increments of 0.06%.
Press the Varispeed button to enable Varispeed mode. The Varispeed LED will light to confirm the
mode. Use the Rotary Wheel to select the desired rate. Pressing Record or pressing the Varispeed
button again will cancel Varispeed mode. Varispeed is currently only available on PCM rates below
50kHz

The two alphanumeric displays provide information about the configuration of the unit as well as
timecode information relating to the currently selected project and media.
Timecode Display
In basic mode the upper alpha-numeric display shows timecode information. The source and format of
the timecode can be adjusted. Displaying frames is user selectable via the Setup menu. Press the
Timecode button to select the source for the Timecode display. The LED adjacent to the Timecode
button shows the selected Timecode source. The interpretation of ABS, REL and EXT is different
depending on the disk format of the selected volume.

Genex FAT32
ABS

EXT Time read from external

Note that, when displaying timecode from an external source, this does not mean that external
timecode will be used as the timecode source for recording. Please see the Timecode section
regarding chasing to external timecode for record and playback.

Absolute vs. Relative Timecode in FAT32 Disk FormatAbsolute vs. Relative Timecode in FAT32 Disk Format
For a FAT32 formatted volume the absolute (ABS) timecode displayed is the timecode coming into or
being generated by the unit and is relative to midnight on a 24 hour timeline. The user can program a
significant point on the 24 hour timeline as a reference point so that all times are measured from that
reference point. In Relative (REL) mode all times, cue points, locates, etc. are marked relative to the
reference point.

The diagram below illustrates the use of the Relative Reference point for an audio clip starting at
01:00:00:00 on the destination timeline.

Press the Timecode Selector button until the REL LED is lit. Locate to the timecode required to be
the relative origin. Press and hold the -/Clear button while simultaneously pressing the Enter button to
mark the point. The display will now show 00:00:00:00.

Absolute vs. Relative Timecode in Genex Disk FormatAbsolute vs. Relative Timecode in Genex Disk Format
The Genex disk format is a linear format where the current time is directly proportional to the physical
location of the audio on disk, much like a tape machine. Absolute time using this format is analogous
to a tape counter with 00:00:00:00 corresponding to the first cluster on the disk. The ABS timecode is
a measure of how far through the disk you are. The Genex format makes a provision for a timecode
track embedded as a sub-code in the recorded audio. The timecode track can be read using the REL
display.

Time Remaining / Cue Point Display
In basic mode, the lower alpha-numeric display selectively shows Disk Time Remaining or the current
Cue Point. Press the adjacent Selector button to alternate between the two displays. Disk Time
remaining is displayed in hours, minutes and seconds only; there are no displayed frames. The Time
Remaining display counting down at a similar rate to the timecode display counting up is a useful
verification that data is being recorded to disk properly.
Cue points are records of events that happened during a recording. An event could be music starting,
a wrong note, the start of a new page, a false start, etc. The GX9000 allows you to log each type of
event as it happens, as a cue point, so that you can quickly and easily find it again. See chapter 12 for
a more detailed description of The Take Logging System.
