      @titosg It's a snippet. Copy it, then in HISE go to File >> Import HISE snippet

        @ustk

        • It depends. Is it linear? Yes, it is linear
        • Does Knob1 need to react back when changing Knob2 or is it one way? I want to set specific values for each value, for example:
          when Knob1 is 1->Knob2 is 1.5
          when Knob1 is 2->Knob2 is 6
          when Knob1 is 13>Knob2 is 7.3

        Is it possible to do that?

        Looks like its not linear - so use a lookUp Table

        var lookUpArray = [1.5,6,7.3,8.1,9.9,12.5,13,15,22,34];
        
        const var Knob2 = Content.getComponent("Knob2");
        
        
        // knob 1's range is set 1 to 10
        
        inline function onKnob1Control(component, value)
        {
        	//
        	Knob2.setValue(lookUpArray[value-1]);
        };
        
        Content.getComponent("Knob1").setControlCallback(onKnob1Control);

          @d-healey Oh ok thank you, I've installed it and it works perfectly, but that's not exactly what I need. Do you know how can I do what I said before? Set different Knob2 values for each Knob1 value

              I'm getting this error message: Interface:! Line 13, column 16: API call with undefined parameter 0 {SW50ZXJmYWNlfHwyNjN8MTN8MTY=}

              The slider is changing its value but it is not affecting the parameter with wich it is linked to.

                The slider is changing its value but it is not affecting the parameter with wich it is linked to.

                The error is telling you that you're using a parameter that doesn't exist aka undefined.

                Just had a quick look at the snippet. Your array only has 10 elements but your knob has 5000 possible values, so you need to do something about that :)

                  I just fixed the error but it still not working, it doesn't change the linked parameter

                  This is what I'm using now:

                  const var Knob2 = Content.getComponent("Knob2");
                  const var Knob1 = Content.getComponent("Knob1");
                  
                  
                  inline function onKnob1Control(component, value)
                  {
                  	
                  	if (Knob1.getValue() == 5)
                          {
                  	        Knob2.setValue(12);
                          }
                  };
                  
                  
                  Content.getComponent("Knob1").setControlCallback(onKnob1Control);

                    @titosg Just use value:

                    const var Knob2 = Content.getComponent("Knob2");
                    const var Knob1 = Content.getComponent("Knob1");
                    
                    inline function onKnob1Control(component, value)
                    {
                    	if (value == 5)
                            {
                    	        Knob2.setValue(12);
                            }
                    };
                    Knob1.setControlCallback(onKnob1Control);
                    

                    Also, no need to getComponent if you already declared it

                    Can't help pressing F5 in the forum...

                      Still not working, it doesn't change the parameter, wich in this case is the release knob from the envelope

                      I just recorded a video: https://vimeo.com/430058912

                        Call Knob2.changed() after you set its value.
