App Note:
Editing Cues
Using the LightCue's Front Panel or CueTool
Now that you’ve got your lighting program recorded, you might want to edit the cues.  How do you do this in the LightCue?  There are two ways.

Editing Cues Directly in the LightCue

Using the on-screen Edit Menu on the LightCue front panel, you can edit the following parameters of your recorded DMX cue:

End Trim:  You can trim frames off the end of the cue so that its duration is shorter than the original recording.  This is especially useful if you’ve recorded a “chase” sequence and you want to loop the cue during playback and have the end seam up perfectly with the start so that the lights chase without a gap or jump.  This edit is non-destructive, and you can always go back to the original length by editing again.

Crossfade Time: If the LightCue has played a cue and is holding a “look” where the DMX channels are static values, you can crossfade all of the channels to the values contained in the first frame of the next-played cue over a set period of time.  This “Crossfade Time” can be edited in this menu.

SMPTE Start (Offset):  When you’ve recorded a cue with active SMPTE connected to the LightCue, the recorded cue gets time-stamped with timecode.  This edit selection allows you to adjust the SMPTE time associated with the first frame of DMX data.  For example, if you started the recording at 01:00:00.00 and want to change it to 01:00:05.00 you can simply dial the new time into the menu and it gets stored in the cue. 

Delete Cue:  This will delete the cue from the media card.

Important Note:  Whenever you record a cue, you should always backup your media card using a laptop or desktop computer using a media card reader.

Using Cuetool.exe to Edit Cues

If you need to accomplish more complex editing of your DMX data, you can use the simple command-line program, CUETOOL.EXE.  The program allows you to convert files recorded on the LightCue to files readable by a spreadsheet program 9i.e. Microsoft Excel).  The DMX data can then easily be examined, graphed, and edited.  CUETOOL.EXE can also convert the spreadsheet-formatted data back into a LightCue-compatible file format so you can playback the edited cue in the LightCue.

Running the program is easy.  Just follow these steps:

  1. After recording your DMX cues power down the LightCue and remove the Media Card media from the unit by unscrewing the two front panel access door screws and pushing the eject button.
  2. Plug the PC Card into a laptop or desktop computer equipped with a Media Card socket.
  3. Copy ALL of the files from the Media Card to you local hard drive.  Copy the files into a separate directory containing the CUETOOL.EXE program.
  4. Copy ALL of the files from the Media Card to your local hard drive AGAIN.  This time, use a different directory called “BACKUP” (or something like that).  This is your backup directory.
  5. Open up a DOS shell, or exit to DOS from Windows.
  6. At the DOS prompt in the directory used in Step 3, type the following:
          Cuetool /E cue00001.dmh cue00001.csv
    This assumes that you want to convert Cue Number 1 for reading into a spreadsheet.  If you want to convert a different cue number, just replace the “00001” part of the filename with the cue number (i.e. “cue00002.dmh” for Cue Number 2, etc.)
  7. Now the cue00001.csv file can be read into Microsoft Excel directly as an ASCII comma-delimited file.  The .CSV extension is recognized by Excel as this particular file type and automatically reads it in with no other prompting.
  8. You can now examine, graph, or edit the DMX data.  Be sure not to insert or delete any columns or rows in the spreadsheet or else CUETOOL.EXE won’t be able to convert the file back into a LightCue file correctly.  You can, however, edit the DMX data values all you want.
  9. If you’ve edited the DMX data and you want to convert the file back to a LightCue file, type the following at the DOS prompt:
          Cuetool /L cue00001.csv cue00001.dmh
    (Same as before – substitute a different cue number if necessary)  Note: Be sure that the extension of the LightCue file is .dmh. (See file naming conventions earlier in this section)
  10. Format the original Media Card in the LightCue to erase all the files (refer to the “File Management Hints” earlier in this section).
  11. Now copy all of the files, including the one(s) that you have edited back to the Media Card from your local hard drive.  Insert the Media card back into the LightCue and you’re ready to playback the edited DMX data.
