Sliderpack resize "issues"

[lalalandsynth]

When Sliderpack is set to for example 16 steps, then changed to 8 steps and then back to 16 , the 8 steps that went out of "scope" have lost their values.

Is there a way to retain the values ?

[d.healey]

You need to store the value of the additional sliders and restore them when the number changes. You can use a data object for this.

[lalalandsynth]

@d-healey Sweet , what is a data object ?
Invisible sliderpack that holds all the values ?

[d.healey]

@lalalandsynth Engine.createSliderPackDataObject() I think... you could also just use another slider pack.

[lalalandsynth]

@d-healey ah , ok , Engine.createSliderPackDataObject() is not in the API as far as I can tell.

[d.healey]

@lalalandsynth

[lalalandsynth]

@d-healey AH I was searching for the "object" part.
Thanks !

[lalalandsynth]

@d-healey Could this method be used for copy/paste shapes with the slider pack and table ?

Or even undo /redo ?
Undo/Redo manager does not work for Scriptnode sliderpacks and tables.

@d-healey said in Sliderpack resize "issues":

You need to store the value of the additional sliders and restore them when the number changes. You can use a data object for this.

That‘s actually pretty hacky. A clean solution would be the possibility of defining a fixed upper limit and then the resizing would just change the pointer instead of reallocating new memory when you resize a slider pack.

This should be rather easy to implement, I‘ll see what I can do later.

[DanH]

@lalalandsynth here's what I'm using...

inline function onARPSLIDERSNUMBERControl(component, value)
{
    		local lastAmount = SliderPack5.get("sliderAmount");
    
        		for (i = 0; i < SliderPack4.get("sliderAmount"); i++)
        {
           	SliderPack4Data[i] = SliderPack4.getSliderValueAt(i);

    	}
    	
   		
        		for (i = 0; i < SliderPack5.get("sliderAmount"); i++)
        {   
            SliderPack5Data[i] = SliderPack5.getSliderValueAt(i);

    	}

					SliderPack4.set("sliderAmount", value);
					SliderPack5.set("sliderAmount", value);
			              	

                    Arpeggiator1.setAttribute(Arpeggiator1.NumStepSlider,value);


	if (lastAmount < value)
    {
            	for (i = 0; i < SliderPack4.get("sliderAmount"); i++)
            	    {
                	    SliderPack4.setSliderAtIndex(i, SliderPack4Data[i]);

                    }
        
        
            	for (i = 0; i < SliderPack5.get("sliderAmount"); i++)
            	    {
               	 	    SliderPack5.setSliderAtIndex(i, SliderPack5Data[i]);

                    }
            
    }
                NOTEAMOUNTLABEL.set("text", Math.round(value));

};
Content.getComponent("ARPSLIDERSNUMBER").setControlCallback(onARPSLIDERSNUMBERControl);

This was for two sliderpacks btw.

Would much prefer @Christoph-Hart's permanent solution however

[d.healey]

Looks like Christoph's solution is ready :)

[lalalandsynth]

@d-healey Awesome!

[DanH]

@lalalandsynth so how do we implement this?

[DanH]

@DanH is it something like

Sliderpack1.setUsePreallocatedLength(16);

Assuming that our max limit of sliders is going to be 16?

[Christoph Hart]

Basically yes, but I haven't pushed the autocomplete yet (I did just now). I also made it accesible through the SliderPack class, not just the SliderPackData class like before.

[DanH]

@Christoph-Hart Thanks. I'm getting 'Unknown Function' error...

[d.healey]

@DanH SliderPack1 not Sliderpack1

[DanH]

@d-healey doh!

[DanH]

@d-healey also is there a better way of controlling multiple sliderpacks from one SP than the below?

inline function onSliderPack5Control(component, value)
{
    SliderPack12.setSliderAtIndex(value, component.getSliderValueAt(value));
    SliderPack13.setSliderAtIndex(value, component.getSliderValueAt(value));
    SliderPack14.setSliderAtIndex(value, component.getSliderValueAt(value));
    SliderPack16.setSliderAtIndex(value, component.getSliderValueAt(value));
};
SliderPack5.setControlCallback(onSliderPack5Control);

I saw a linkTo API....

[d.healey]

@DanH If you want them to be completely linked, so that changing one will always change the others, then you can use a data object.
