[QLab] Loop group

[Burki Kay]

I want a group of samples to be fired randomly and endlessly (sort of looping the group). Anyone an idea? Thx!

Make 3 cues thus:

Cue 1: Group Cue containing the Audio Cues; set to fire all children simultaneously

Cue 2: Script Cue; set to auto-continue

tell front workspace
set possibleCues to cues of cue "1" whose running is false
try -- In case there aren't any possible cues
set randomCue to some item of possibleCues
set post wait of cue "2" to duration of randomCue
start randomCue
end try
end tell

Cue 3: Script Cue

tell front workspace to start cue "2"

Cue 1 can be in a separate cuelist (or could even _be_ a cuelist). Cues 2 & 3 need to be consecutive. It is important that cues 1 & 2 are numbered "1" and "2" for the scripts to work.

Fire cue 2 and it will find a cue in cue 1 that isn't playing, set the post wait of cue 2 to be the duration of the cue it has picked and then start the cue. Once the duration has passed, the auto-continue will fire cue 3, which will start the process again. It isn't strictly necessary to look for a cue that isn't playing (I think), but I started from a script that did that.

A Stop Cue targeting cue 2 will end the loop.

Wow, thanx a lot. I'll try that!

I realize this is an old thread, but I thought I'd post an updated answer for QLab 3 in case anyone comes looking (I reinvented the wheel on this so I went searching for answers and didn't find any I found sufficiently easy).

In a new cue list (let's call it "random cues"), make a group (cue A) and set it to the mode that plays a random child then moves to the next cue. Have this group and each member of it auto-follow. 

Below this group, create a play cue (cue B)  that targets cue A (the group above). Test this, but it should play randomly and infinitely.

In your main cue list, when you want to start your random playback (video or audio), create a play cue that points to "random cues" OR to cue A (either will work).

When you want your random playback to end, create a stop or fade cue in the main cue list that points to "random cues" OR to cue A. Don't try to point to individual members of the group as you'll cause yourself a lot of headaches and it won't work.

Hope that was clear!!

Cheers,

Kerry

Thank You

If you read this I could really use help. This doesn't work in Qlab 4. It crashes all each time I try it. I want my group of music tracks together. When I fire that group I want one song to play, then the cue to moe to the next "start cue" that targets the musical group that is set to play random child only after whatever cue in the group finished playing. I tried your steps but it crashes the software every time. Tried new workspace.

This seems like it should be simple to just have a loop, but it's not working for me.

Kerry’s very neat solution works in QLab 4 for me:
