An efficient way to script functions for multiple knobs?

[d.healey]

@orange Is there a reason you're using callbacks rather than connecting the knobs via parameter I'd?

[Christoph Hart]

@d-healey I'm guessing he's setting the scriptnode parameters directly.

If you use an array for the parameters and UI elements, you can use a single callback like this:

// Make sure that they have the same length and the positions match
const var Parameters = [...];
const var Knobs = [...];

inline function onKnob(component, value)
{
    local idx = Knobs.indexOf(component);
    Parameters[idx].setValue(value);
}

for(k in Knobs)
    k.setControlCallback(onKnob);

I used that in case of the multiple parameter modulations for each knob (I generally use more than 1 setAttribute for each knob :) ).

If each knob controls just one parameter, then they can be connected to the Parameter Id's too.

@tomekslesicki If I know the knobs are named similar and also the effects (as in this case) I usually use

const knbs = Content.getAllComponents("Knob");
const gains = Synth.getAllEffects("SimpleGain");

to get arrays for both the components and the modules and then I set it up like this:

Thanks guys, I got it working! Christoph was right, I'm controlling Scriptnode parameters so both attribute and values are set from the main script.

[Christoph Hart]

@tomekslesicki is there a particular reason for controlling the parameters instead of connecting them to root container parameters and then using setAttribute?

[tomekslesicki]

@Christoph-Hart yeah, I have too many scriptnode parameters and there's a bug where after a certain number, they don't work when set like that. So I'm using parameter numbers and that works fine as a walkaround.

By the way - can I use the method you suggested here to change the width of multiple panels as well?

[Matt_SF]

@tomekslesicki which commit are you using? IIRC Christophe fixed the scriptnode param number bug recently.

Of course. Also you can automatically create those arrays of UI components when you have selected more than one and use the „Create script variable declaration“ function in the context menu.

[tomekslesicki]

@Matt_SF oh, really? I'd have to check the most recent ones then!

@Christoph-Hart I know this, love it and use it daily! I just guess my assumption that something like this:

Content.setPropertiesFromJSON(Panel[idx], {
"width": fancynumber
});

...would work is not correct so I bet I'm missing something very obvious.
