I'm very new to Kyma and I'm helping a researcher who has designed the sound in the above image. I want to change either the Delay parameter or the DelayScale parameter of the DelayWithFeedback module labeled B400.

I want it to choose a random number between 400 ms and 600 ms each time the sound is played. But no matter how I do it, I keep getting it wrong.

My current scheme is to use the DelayScale parameter, set it to a random number between 0 and 0.3333 and then add 0.6666 to it. That should give me a number between 0.6666 and 1.0. In the Delay parameter I have 600 ms. So, I should get a number between 2/3 of 600 ms (i.e. 400 ms) and 600 ms itself. Right now I have:

(((1.0/3.0) random abs) + (2.0/3.0))

2/3 + ((1/3) * (1 nextRandom abs))

You were right in the theory: (2/3) offset + (1/3) range.

A couple things:
I am pretty certain you have to use * to signal multplication and that 2(X) does not work.

nextRandom generates new number on each trigger in this case 1 is the trigger, which is upon compiling when stated as a 1.

One suggestion is to trigger the nextRandom number by the trigger sound that is a couple objects to the left (thich I am guessing is triggering a sound).

To do that the argument should read: 2/3 + ((1/3) * ([pasteTrigger] nextRandom abs)).

(2.0/3.0) + ((1.0/3.0) * (1 nextRandom abs))

The sound containing this is started and stopped several times by a Tool. Analysis indicates that it doesn't seem to vary the delay as much as we expected.

(2.0/3.0) + ((1.0/3.0) * (!trigger nextRandom abs))

So unclicking the DelaySmoothing is a start.

I suggest either a trigger or a variable which then allows you to control the rate which the random values are generated. This just provides more control and allows you to play with the delay and tune it to the desired effect. You could get dynamic and have it triggered off the trigger generator you already have there. Again, just some ideas, not sure what the desired effect you are going for.

Also, other options for generating random numbers include swapping in white/pink/hotpink noise generators. Each provide a different level of control and output property, which may or may not be interesting your ends.
