There are 5 Paths numbered PAN 1-5 with different paths drawn in the 2D fade well of an OSC message in a Network cue. The workspace can store any number of patterns in the group cue PATTERNS which is nested in another group cue numbered LOOPGROUP. The next cue in the group disarms all Pan Paths. This allows the same script to be used for other cues with different audio, e.g if we had another group cue with a train effect in an audio cue numbered TRAIN the OSC message would set the notes of cue SCRIPT to TRAIN.

This is followed by a Network cue which sets the notes field of the cue numbered SCRIPT to the number of the audio cue we are using, in this case, cue HELI. We can then use a script with some maths functions to take these coordinates and interpret them as 4 slider levels which will give a voltage panned output that approximates the cursor position on a quadraphonic soundstage.Ĭue 1 is a ‘fire all children’ group cue which contains the mono audio cue matrixed to 4 sliders corresponding to L, R Ls & Rs.

This allows us to use the x and y translation of a dummy video cue, (a disabled text cue works very well for this), to store the current values of the x and y coordinates of the current cursor position on a drawn path in a 2D OSC fade. The new QLab 4.2 feature which enables this project is the OSC message: Because you may not have a multi-channel playback system with which to listen to the demo, I have encoded the soundtrack as a binaural recording for playback on headphones.
