Setting ControlCallback w/ Loops ?

[Orvillain]

Is that the full script? You don't seem to ever be calling allSampleVolumeKnobs ???

[Chazrox]

@Orvillain sheet. lol. See.. I told you im goofing it. all the loops got me in a loop. lol. Im not exactly sure how to go about that at the moment. Im definitely mixed up a little bit but still trying to figure it out.

@Chazrox

const TheGains = [];
const  SampleVolumeKnobs = [];

const NUM_COMPONENTS = 8;

for(i = 0; i< NUM_COMPONENTS; i++)
{
    TheGains[i] = Synth.getEffect("Simple Gain" + (i+1));

    SampleVolumeKnobs[i] = Content.getComponent("knbVolume" + (i+1));
    SampleVolumeKnobs[i].setControlCallback(onSampleVolumeKnobsControl);
}

Or even shorter...

const TheGains = Synth.getAllEffects("Simple Gain");
const SampleVolumeKnobs = Content.getAllComponents("knbVolume");

for(k in SampleVolumeKnobs)
	k.setControlCallback(onSampleVolumeKnobsControl);

Or even shorter...

// Don't do this, I'm being silly
for (k in Content.getAllComponents("knbVolume")) k.setControlCallback(onSampleVolumeKnobsControl);

I always thought there was "no guarantee of ordering" in getAllComponents.....

[d.healey]

@Lindon I think it grabs them in the order they are in the component list. I never really thought about it though but I haven't ran into any issues.

[Lindon]

@d-healey yeah..maybe then , however your suggestion makes the callback difficult in that there is no indexOf(component) to show you which one is being called on...unless theres some fu I dont know about...oh I just noticed your "dont do this comment..>"....

[d.healey]

@Lindon I did put a disclaimer not to use it. :)

{
    TheGains[i] = Synth.getEffect("Simple Gain" + (i+1));

    SampleVolumeKnobs[i] = Content.getComponent("knbVolume" + (i+1));
    SampleVolumeKnobs[i].setControlCallback(onSampleVolumeKnobsControl);
}

@Chazrox ...and now your call back looks like this:

inline function onSampleVolumeKnobsControl(component, value)
{
	pos = SampleVolumeKnobs.indexOf(component);  //tells us which control is being called...
       TheGains[pos].setAttribute(TheGains[pos].Gain, value);
};

@Lindon Thank You Im gonna try this in a bit and get back to you. Appreciate it! Love the energy.

@Lindon
Yes, the components will be added in the order specified in the component list.

As for the index, I use a function that I call first in the callback and that returns the index. Something like this:

inline function getIndexAsInt(component)
{
	local index = component.getId().replace("knbVolume", "").getIntValue();
	return index;
}

inline function getIndexAsString(component)
{
	local index = component.getId().replace("knbVolume", "");
	return index;
}

The return value can then be used in the callback to determine the correct component....

local index = component.getId().replace("knbVolume", "").getIntValue();

If you are storing all your components in an array you can get the index directly using indexOf

@d-healey
Yes, that's right! Thanks for the tip! :-)
