Hello,
I would like to use an audio trigger to drive some derby or laser motors on my multi effect bar.
If I use a direct DMX signal or a VC Slider from the audio triggers I have a pretty raw/jerky move.
I have then tried to use the Audio triggers to set a speed dial value. I use that way to set speed of some chasers (with fade In for instance) but then I have not found a way to connect the speed dial to a slider (or kind of).
Any help would be appreciate
edit: maybe a solution would be to have an option on the audio triggers to sent DMX (and/or also when sent to VC Slide) the value every "x" ms so that the fixture would have time to adjust by itself the motor speed and so have something smooth instead of having multiple change all the time.
Audio trigger and slider smooth move

You will need some Loopback Magic for this to happen... MichelSliepenbeek https://www.qlcplus.org/forum/memberlis ... ile&u=9728 has lots of nice examples. I'd check his posts.

Try this:
Above the Slider you will find the Speed Dial (you should add your Functions to it).
On the Input Tab you will see that it uses Loopback Channel 1 as External Input (feel free to change the Range to match with your functions).
The Slider sets the Loopbback Channel.
The Audio Trigger uses the Slider.
It is important to use a seperate Universe for your Loopback Channels.
If you check the Input/Output Tab you will see that:
- Universe 1 is for Fixtures (and outputs to a USB DMX dongle).
- Universe 3 is for Loopback and outputs to Loopback 1 (which again is input for Universe 1).

That would be an other option: use a Channel Modifier https://docs.qlcplus.org/v4/fixture-man ... properties.
Modifiers like Logarithmic or Exponential for instance might give you a smoother response.
And you can even use a channel modifier on a Loopback Channel: you have a lot of options.

so now I think I have everything I need to rewrite my project
Last question I have is : I use a VC audio trigger to set the duration of a Speed dial. The speed dial then set some Cue list speed. Nothing special here.
My music style has some momentum and then break/drop for voice or just some melody and then go back to momentum with kick. Basically let's say EDM/Techno.
The Audio trigger and all the tuning we can do using frequency or volume is more than enough for my usage but there is a behavior I would like to improve : sometime (or pretty often I would say) bpm is let's say at 138... then suddently come the voice (no more audio hit as my low freq or even volume trigger is below threshold)...in this scenario the speed dial stay at the previous speed and so the light are too fast. I would like a calm down period.
Is there a way to say something like : if the audio trigger has not received new sound that match the trigger settings for n (m)seconds sent a default value (like something slow) to the speed dial ?
