Figure 77 - Choosing Midi Time Code as the clock source.
Now the timings in the cue list will refer to the midi time code that comes from the tape deck or midi sequencer connected to the catalyst computer.
To control the play back of the cues from the space bar, enter the cues without placing any times. Between each group of simultaneous cued states place a wait symbol by clicking on the grey double lines in the wait column.

The next group of cued states will not be played until you press the space bar again. The next cue is indicated by the red dot in the left column.

Figure 78 - A cue list using the wait symbol.
If you want to step through the cues one by one use the enter key. This is useful in case you are trying to solve a technical problem and need to step through each cued state individually.
Some lighting consoles send out midi show control commands when a cue is run on the console. For example the Hog 2 sends out a cue number and a playback number in a midi show control Go command. This Go command can trigger play back of cues in the cue list.
