LightJockey Help
CD-Audio
Enabling CD-Audio allows LightJockey to control a CD-ROM drive for audio CD play back. It also
allows LightJockey to take time code from the audio CD to synchronize the cue list to audio CD time
code. See Audio CD Control and Using time code in cue lists for more information. Note that in newer
Windows versions application control of CD-ROM drives has become... errhhh.. troublesome. If
possible, copy the CD tracks to hard disk (use any 'CD ripping' application - for example Windows
Media Player to copy the track to hard disk) and use the LightJockey MediaPlayer to playback the
digital audio file rather than using the CD directly.
Digital Audio Playback
While not strictly a piece of hardware, LightJockey is able to connect to Winamp for playback of
digital audio (MP3, Wav, etc..). The time code from the digital audio may be used to synchronize
sound and light in the cue list. Note that LightJockey connects with Winamp 2 (version 2.74) only.
See uising Winamp for digital audio and using time code in cue lists for more information. In order for
LightJockey to automatically start Winamp when required (through in the cue list), the complete path
to the Winamp executable must be entered in the 'Path to Winamp' field. Click and navigate to
the Winamp.exe file.
LightJockey MediaPlayer
The LightJockey MediaPlayer is a separate module distributed with LightJockey that encapsulates
core functions of Windows Media Player. LJ MediaPlayer may be used to playback different media file
formats, including digital audio and video files. The MediaPlayer requires Windows Media Player
version 6.0+ installed on the PC. The LJ MediaPlayer is exclusively used in cue list context and
requires no initial configuration. For more details see LightJockey MediaPlayer
Audio CD control
In order to get access to the audio functions from the CD-ROM drive, the drive must be configured in
the hardware setup dialog.
After configuration and a restart of LightJockey, the CD audio control is available via on the cue
list tool bar
Audio CD control
The CD control functions like any domestic CD player, play, forward, next track etc. The drag bars
may also be used to set the playing position. When the CD time-code is used to drive a cue list
elapsed disc time is always used.
Analogue vs. digital playback in Windows 2000 and XP
Windows 2000 and XP offer the option to playback CD audio mode - which may be a great option if
there is no analogue connection from the CD/DVD drive to the sound card. The response time from
the digital mode driver seems to be much faster than the analogue driver.
However, experience shows that in digital mode the 'true' time code update rate may actually be much
slower than in analogue mode - the digital audio driver simply just returns the same time code for
sequential time code requests.
The best way to check for the 'real' time code update rate is to open an empty cue list. Then open the
