Channel random values

Hi all.

Is there a way to assign random values to a channel ?
I mean set a min and a max, and play the values in between randomly.
Like a strob function that play from 0 to 127, but instead of a fixed frequency, it would be randomly.

I see an application if you want to implement random in variation of intensity, in strob speed, in color etc....

If not possible, how could we approach that effect ?
In some other soft that I have tested, they use curve that looks random if they are well set and tuned.

Chasers do have random order. So create a couple of scenes, add them to a chaser and set order to random. Create VC Cue list, add speed dial to control the speed.

Curve: you may create channel modifier curve (http://qlcplus.org/docs/channelproperties.html) that permutes the values so they look randomly.
The problem is that it will be on for all times. You can't turn it on/off temporarily. You can only remove it altogether from a channel.

But: using it on a fake dimmer channel with loopback plugin you may be able to create something that would work temporarily.

You can also use a script:
setfixture:1 ch:2 val:random(20,235)
