3 band EQ controls via script

[d.healey]

Your GUI has a lot of controls, I have no idea which knob controls the EQ.

Make a simple project with 2 EQs and 2 knobs, once you get that working you'll know what to do.

@d-healey Ok will do, thanks :)

@d-healey Sorry to bother you again David, here is a snippet with two controls only.
As you can see, they both affect EQ1...

As you can see, they both affect EQ1...

They also both affect EQ2

Is there a reason you're using a callback instead of parameter/processor ID?

I think you'll benefit from this video
https://www.youtube.com/watch?v=T40GCkxx8iw

This piece of code should be 1 loop, you have 3. (Edit: Actually I see in your real project you have consolidated them) :) .

for (i = 0; i < 2; i++)
{
	EQ[i] = Synth.getEffect("EQ"+(i+1));
}
	
for (i = 0; i < EQ_CONTROLS; i++)
{
    freq[i] = Content.getComponent("freq"+(i+1));
}


//Function

for (i = 0; i < EQ.length; i++)
	{
		freq[i].setControlCallback(changeFreq0);

	}

This array could have a better name

const var freq = [];

Something like:

const var sliFreq = []

So we know it contains sliders and not frequency values for example.

@d-healey Thanks a lot!

[alepan]

@d-healey The reason why I'm not using the parameter/processor ID is that in my real project is that I have a lot of controls and I wanted to avoid having hundreds of lines of scripting repeating the same commands. Maybe I am wrong :)

[d.healey]

@alepan Parameter ID requires no scripting, just select the processor and parameter in the interface designer.

@d-healey said in 3 band EQ controls via script:

Yeah I know, the fact is that only the first band is accessible in that way, and I have three bands in each eq.

I really can't figure out why all eqs are controlled by each slider. If you think it possible, can you explain me where the problem lies?

Oh I didn't know that.

You have a loop that is doing the same thing to each EQ. Dismantle your loop and write it out line by line instead and you'll see why it's doing what it's doing.

[alepan]

@d-healey OK I managed to do it :)
I needed a local variable to get the IDs of the component being used and an if statement to compare that number with the counter:

inline function changeFreq0(component, value)
{
		local idx = freq.indexOf(component);
		for (i = 0; i <= 13; i++)
		{
		    if (i == idx)
                EQ[i].setAttribute(EQ[i].Freq, value);	
		}
}

Thanks a lot for the support David :)
