Function switching on audio detection

[davidf]

What I'd like to achieve is a situation where QLC can be left running unanttended, which will switch between functions depending on the presence or absence of an audio signal. This is to provide one light sequence in time with music, and a different sequence for when no music is being played.

In my Virual Console, I have within a Solo Frame, a chaser sequence and a button. The button runs a RGB Matrix function. The Chaser Sequence has been added to a Queue List which I am stepping through at a speed governed by a speed-dialer whose tap tempo is being controlled by an Audio trigger's VC widget. This works reasonably well in the presence of an audio trigger (although a beat detector would improve this significantly).

I'd like to 'automate' the process of activating RGBMatrix/ Cue list function according to the presence of audio, something like:

Music Playing:
Stop RGB
Start Cue List

No Music playing:
Stop cue list
Start RGB

Is this possible?

Many thanks

David

I'm not 100% sure what you want to achieve (sharing workspace file would help).
But the loopback plugin maybe can do the trick for you. Just have a look at it and ask again with more information provided, if you get stuck.

If you understand german I can really recommend this video tutorial: https://www.youtube.com/watch?v=SjgdwvK-J6w

Thanks-My description isn't very clear, admittedly. I'll checkout the Loopback plugin to see if it looks useful

(I know only one sentence in German, but knowing how to ask which platform the train for Ostend leaves from is of limited use )

Thanks again!

You could probably achieve this with an audio trigger set to release on level=0.

- Make a chaser with 2 steps: Static scene and music chase (you can put chasers as steps in a chaser).
- Make it loopabel with holdtime = infinity.
- Make cuelist widget with this 2 step chaser, and trigger it from audio trigger with release level 0.

This should flip flop between static and chase every time the music comes on and off. Only problem is that you will trigger static scene every time there is a general pause in the music...
