NewBe Question about Link

[d.healey]

A control can either use a custom callback or parameter ID, not both.

[MikeB]

And how do I get it to work via script?
Or rather how do I get the ProcessorID and ParameterID
into my custom callback?

Can you show me an example script/snippet
I learn fast when I see this than when I just read it

[d.healey]

First 15 minutes of this video should cover it

@MikeB There are several ways to do this. I would do something like that:

I used 2 Simple Gain units in this example.

Or alternatively, you can directly get the Knob values with .getValue() and use this value in the .setAttribute.

[MikeB]

It works - both according to David's video as well as
your snippet - thanks
BUT: Now I get although all seems right constantly the error message: Line 32, column 23: API call with undefined parameter 0

If I comment out the line the next one is shown

[d.healey]

@MikeB Is this error happening in the snippet you posted?

[MikeB]

yes and in this:

const var SimpleGain1 = Synth.getEffect("SimpleGain1");
const var SimpleGain2 = Synth.getEffect("SimpleGain2");

const var Knob1 = Content.getComponent("Knob1");
const var Knob3 = Content.getComponent("Knob3");
const var Button6 = Content.getComponent("Button6");


inline function onButton6Control(component, value)
{
	  if (value)
    {
        local Knob1_value = Math.randInt(0, 16);
        local Knob3_value = Math.randInt(0, 10);
        
        Knob1.setValue(Knob1_value);
        Knob3.setValue(Knob3_value);
        
        SimpleGain1.setAttribute(SimpleGain1.Gain, Knob1_value);
        SimpleGain2.setAttribute(SimpleGain2.Gain, Knob3_value);
    }
};

Content.getComponent("Button6").setControlCallback(onButton6Control);

Whereas this is line 31: Knob1.setValue(Knob1_value);

[d.healey]

Nothing obvious is standing out to me. Could you post a HISE snippet? and I'll try it on my system.

[MikeB]

Works all of a sudden again - Strange.
But I have already read here that this probably occurs more often Probably more often if you try around so much as I still do. Copy/Paste/Compile/Delete etc.

[Lindon]

Slight changes to your code -

• Shout if its not making sense...

const var SimpleGain1 = Synth.getEffect("SimpleGain1");
const var SimpleGain2 = Synth.getEffect("SimpleGain2");

const var Knob1 = Content.getComponent("Knob1");
const var Knob3 = Content.getComponent("Knob3");
const var Button6 = Content.getComponent("Button6");


inline function onButton6Control(component, value)
{
    if (value)
    {
        Knob1.setValue(Math.randInt(0, 16));   
        Knob1.changed();
        Knob3.setValue(Math.randInt(0, 10));   
        Knob3.changed();

    }
};
Content.getComponent("Button6").setControlCallback(onButton6Control);

inline function onKnob1Control(component, value)
{
    SimpleGain1.setAttribute(SimpleGain1.Gain, value);
};
Content.getComponent("Knob1").setControlCallback(onKnob1Control);

 inline function onKnob3Control(component, value)
 {
     SimpleGain2.setAttribute(SimpleGain2.Gain, value);
 };
 Content.getComponent("Knob3").setControlCallback(onKnob3Control);>
