Change Sample map via Prev-Next Button

[Tania Ghosh]

@d-healey @iamlamprey
Can you correct the code?

Content.makeFrontInterface(500, 400);
const var Sampler1 = Synth.getSampler("Sampler1");
const var prev = Content.getComponent("prev");
const var next = Content.getComponent("next");




const var smpmap = Sampler.getSampleMapList();
const var cmbsmp = Content.getComponent("cmbsmp"); //ComboBox

cmbsmp.set("items",smpmap.join("\n"));


inline function oncmbsmpControl(component, value)
{
	Sampler1.loadSampleMap( smpmap[value-1]);
};

Content.getComponent("cmbsmp").setControlCallback(oncmbsmpControl);


inline function onprevControl(component, value)
{
if (value)
{
    cmbsmp.getValue > 1 ? cmbsmp.setValue(cmbsmp.getValue() - 1) : cmbsmp.setValue(1);
    cmbsmp.changed();
}
};

Content.getComponent("prev").setControlCallback(onprevControl);



inline function onnextControl(component, value)
{
if (value)
{
    cmbsmp.getValue > 1 ? cmbsmp.setValue(cmbsmp.getValue() + 1) : cmbsmp.setValue(4);
    cmbsmp.changed();
}
};

Content.getComponent("next").setControlCallback(onnextControl);

Currently I have 4 sample Maps. It is working but only two steps.

@iamlamprey said in Change Sample map via Prev-Next Button:

@Tania-Ghosh I just used a nested if statement

if (value)
{
    if (cmbsmp.getValue > 1)
    {
        cmbsmp.setValue(cmbsmp.getValue() - 1);
        cmbsmp.changed();
    }
    else
    {
        cmbsmp.setValue(whateveryourmaxvalueishere);
        cmbsmp.changed();
    } 
}

Then do the opposite on the + button, if it's reached your max value, then go back to 1

in my case i just ignored the event if it would otherwise go "out of bounds", instead of wrapping round (i guess that's what Lindon meant)

thats what "wrap around" means....

@Tania-Ghosh Hint: Both your previous and next buttons are checking for the same condition

@d-healey I really have to learn that single line if statement wizardry

@Lindon took me a minute

@iamlamprey Thnaks i have modified the code. Now ERROR is

Interface:! Line 17, column 24: API call with undefined parameter 0

Line no 17 Giving me the error. ComboBox and Buttons working to change sampleMaps but it is throwing ERROR after reaching out bounds/wrap around.

Content.makeFrontInterface(500, 400);

const var prev = Content.getComponent("prev");
const var next = Content.getComponent("next");




const var smpmap = Sampler.getSampleMapList();
const var cmbsmp = Content.getComponent("cmbsmp"); //ComboBox

cmbsmp.set("items",smpmap.join("\n"));


inline function oncmbsmpControl(component, value)
{
	Sampler1.loadSampleMap( smpmap[value-1]); //Throwing error
};

Content.getComponent("cmbsmp").setControlCallback(oncmbsmpControl);


inline function onprevControl(component, value)
{
if (value)
{
    if (cmbsmp.getValue < 1)  // > didn't work so <
    {
        cmbsmp.setValue(cmbsmp.getValue() - 1);
        cmbsmp.changed();
        
    }
    else
    {
        cmbsmp.setValue(4); // I have 4 Sample maps 
        cmbsmp.changed();
    } 
}
};

Content.getComponent("prev").setControlCallback(onprevControl);



inline function onnextControl(component, value)
{
if (value)
{
    if (cmbsmp.getValue < 1) // Same here
    {
        cmbsmp.setValue(cmbsmp.getValue() + 1);

@Tania-Ghosh add whatever functionality to your combobox

This is exactly the function I am trying to code for the Audio Loop Player
How can I implement this for it?

[Tania Ghosh]

@ulrik Yeahhhhh... Superb Thank you so very much :)
Working perfectly.

[Tania Ghosh]

@iamlamprey Awesome. Thank you :)

[A Former User]

@MikeB I'm not familiar with the Audio Loop Player, what are you trying to do?

[ulrik]

@MikeB do you have a snippet so we can see what you mean?

[MikeB]

It works exactly once - then it doesn't work anymore?!??

Sidenote friends, I use Console.print(whateveri'mtryingtofigureouthere) religiously when something isn't working. I also try and approach it from a logic/pseudocode perspective, an example would be:

1. What is button "Next" supposed to do?
   A. Increment another control. So Slider.setValue(Slider.getValue + 1).

2. Why isn't the "target" control updating?
   A. Because we need Control.changed()

3. Why is the button sticking?
   A. Because it's not Momentary.

4. Why is it calling the function twice?
   A. Because we need to add a check to ONLY call it when it is ON (value of 1).

5. Now it works but the slider is going to infinite/negative infinite!
   A. Now we add a check, if the slider is already its MAX value, we set it to its MIN value, or vice-versa for prev buttons. This done with an
   if statement.

Incremental/iterative logic helps me arrive at a working solution, after that it's just optimizing the code for performance/readability.

Hopefully this helps someone :)

[MikeB]

Great thank you very much.
I have found the error.
The slider was not from 0-5 but from 1-6 so HISE crashed every time.
Probably because there is no "sample07".

And here is the finished snippet - Prev/Next/Random load sample in AudioLoopPlayer
