[SOLVED] Changing Key Colors with Samplemaps

[Soundavid]

Hi, I have an Instrument with different Samplemaps that change with Radio Buttons, these Buttons Change the Samplemap and the image, I try to colour the Keyboard putting the code in this Callback but I have to double click the button to make this function work on the Keys. I tried putting the code in a hidden Slider, Panel but have the same result, I also tried a timer and it works but I don't like that timer running and sometimes glitching the Key Colours, some ideas?

This is my code

inline function changeInst(component, value)
{
	
    if (value)
    {
        local idx = instButtons.indexOf(component);

        for (i = 0; i < insts.length; i++)
        {
            insts[i].showControl(false);
            Sampler1.loadSampleMap(Samplemap[idx]);
            
        }
          
        for (i = 0; i < 127; i++)
        {
         Engine.setKeyColour(i, Colours.withAlpha(Colours.black, 0.6));
                           	    
         	if (Sampler.asSampler().isNoteNumberMapped(i))
         	{
	         Engine.setKeyColour(i, Colours.withAlpha(Colours.dodgerblue, 0.4));
         	}
               
        }  

        insts[idx].showControl(true);
    }

}

I have "Sampler" Referencing Child Synth and "Sampler1" Referencing Sampler in order to make this work.

@Soundavid My first guess (without any investigation) is that your re-colouring triggers before the new sample map has finished loading, therefore it won't detect the note numbers as being mapped/unmapped at the point your loop runs. If you put the key colouring code in a preload callback you might get better results.

@d-healey You were Right! I tried this code in a hidden Panel and works Perfectly! Thanks man.

ScriptPanel1.setLoadingCallback(function(isPreloading)
{
	if(!isPreloading)
	for (i = 0; i < 127; i++)
	{

	Engine.setKeyColour(i, Colours.withAlpha(Colours.black, 0.6));
	                   	    
	if (Sampler.asSampler().isNoteNumberMapped(i))
	Engine.setKeyColour(i, Colours.withAlpha(Colours.dodgerblue, 0.4));
	
	}  
});
