@Christoph-Hart Well, I'm not sure it is what I want to do, this will clutter a lot my interface and component list. Also I noticed that having too many widget in an interface makes it laggy. And, my vector knob has already all the options I need...
I really think adjusting from the skew factor would be better in my case.
It's already what Hise is using, isn't it? So what are the maths after calculating the skew?
Also, I found some methods in Juce for mapping the values from a skew factor or mid-point, maybe it would be cool to have it in Hise what do you think?
