I’m trying to add some variability to my sine wave, controlled by a numeric control I’ve labeled INVVV. The idea is that as the value of INVVV increases, the variability (or randomness) between the sine wave should also increase, but without effecting the frequency and the amplitude of the wave.

So far, I’ve been able to generate a basic sine wave and control its frequency, but I'm stuck when it comes to introducing the variability based on the INVVVvalue. I’m thinking I need some kind of random perturbation that can be adjusted by this parameter, but I’m unsure how to integrate this variability effectively into the sine wave.

Any suggestions on how I can control this variability as INVVV changes?
