[Updated for QLab 4.1 13 Jul 17]
Prior to QLab 4, there was no inbuilt tool to record sequences of cues in real-time. The method below is for QLab 3 users. It is obsolete in QLab 4. Here is the Record Cue Sequence window, accessed from the tools menu in QLab 4
Details of how to use it are in the QLab 4 documentation online here.
For QLab 3 Users:
If you need to create a large number of OSC or MSC cues, (or any other cue types for that matter), timed to specific points in an audio or video cue, this workspace might be useful.
You can play an audio or video cue, and hit a hotkey every time you want to create an OSC or MSC cue, ‘ on the fly’. When you hit the hotkey a cue is created, with a pre-wait corresponding to the elapsed time of the cue you are setting your markers to match. When all your cues are created, another hotkey will group the created cues with the media cue.
Here it is in action:
How It Works:
When the hotkey is pressed “§” the GEN cue script is triggered.
It makes a new OSC cue and sets its pre-wait time to the elapsed time of the running audio or video cue. it sets the properties of the OSC cue, in our example to patch 2 (it assumes 1 is used for localhost) and with an OSC custom message type. You edit this script to include the OSC custom message you want to be programmed where indicated.
When you have finished marking the cue points you manually select all the new OSC cues and the sound or video cue the pre waits relate to, by shift-clicking. You then press “G” to trigger the Grouping.
This script stores the cue name and number of the sound or video cue, makes a group cue, and places all the selected cues within it, sets the mode to fire all, and gives the group cue the original number of the sound or video cue, and a name based on the original name.
You can download the workspace here
It requires QLab v 3.1.10 to function.
If you need to make MSC cues with specific cue numbers included, this script or a variation on it, should do what you want. Create a script cue and number it MSCG. Assign a hotkey to the script and use in the same way as the OSC example above.
Every time the script is run an MSC cue is created, in this example an MSC go with a cue number, and the cue number for the MSC is incremented by 1. Because QLab doesn’t facilitate global variables you have to find somewhere to store them. In this case we are using the notes field of the script cue. Before generating a sequence of cues, set the number in the notes field of the script cue to the first MSC cue number you want to generate in the sequence.
The script should be easy to adapt for other MSC messages. Script hooks you may find useful when referring to parameters in MSC cues are:
deviceID (integer) : MIDI Show Control device ID.
command format (integer) : MIDI Show Control command format.
command number (integer) : MIDI Show Control command.
q_number (text) : Q Number message parameter.
q_list (text) : Q List message parameter.
q_path (text) : Q Path message parameter.
macro (integer) : MSC macro.
control number (integer) : MSC control number.
control value (integer) : MSC control value.
