@ustk said in Inverting a knob:

@Ender you already have value as callback's argument

So:

inline function onKnobControl(value)
{
	local invVal = 1-value;
	
	Console.print(invVal);
}

Hello @ustk ,

I just had to do some little adjustment to the function you wrote and everything works like i want :)

Thank you very much for your help!

Hello everyone,
i'd like to invert a knob, so the minimum value would be 1 and the maximum 0. Using the properties of the knob doesn't work and found this post (https://forum.hise.audio/post/14243)

While i understand the idea of this simple line, i don't know how to implement it in a function linked to my knob. Here's what i wrote (I have some experience with C# and a tiny bit of Unity3D oriented Javascipt, so i'm a newbie with Hise scripting ):

const var knobAmount = COntent.getComponent("LFOAmount");

inline function onKnobControl(value){
	1-amountKnob.getValue(0, 1);
}

I'm sure i miss something simple, but i can't figure out what...

Thanks in advance!

I found what was wrong!
put it back to local filterIndex = value - 1; , but the same message came again. i suddenly thought abput the name i gave to the filter module. I changed it and everything worked well! i maybe got the issue because i left a space in "MAIN FILTER".

I'm so glad to see this filter behaving like i want it to do so. Thank you so much for your help, i would probably be mad if you didn't answer to my post :)

@d-healey did a right-click on the filter in module tree => create generic script reference.

Then i used the line written in the console to replace the filter const var. i still get the same API call error, and the filter type doesn't change at all. here's a screenshot of what i did

@d-healey i tried to reference the filter with this:

const var filter = Synth.addEffect("PolyphonicFilter", "MAIN FILTER", -1);

but i get API call with undefined parameter 1

What should i use for the last parameter in the Synth.addEffect line?
here's my code again,

const var filter = Synth.addEffect("PolyphonicFilter", "MAIN FILTER", -1)
const var comboBox = Content.getComponent("FilterType");
const var modes = Engine.getFilterModeList();

const var myFilters = [modes.LowPass, modes.HighPass, modes.BandPass];

comboBox.addItem("LowPass");
comboBox.addItem("HighPass");
comboBox.addItem("BandPass");

inline function onComboBoxControl(component, value)
{
   local filterIndex = value - 1;
   filter.setAttribute(filter.Mode, myFilters[filterIndex]);

}

comboBox.setControlCallback(onComboBoxControl);

@d-healey said in Parsing Error:

You don't have a reference to your filter effect, you have a component reference called filter.
How can i add this reference? I thought

const var filter = Content.getComponent("MAIN FILTER");

was the way to reference the filter. I'm used to C#, and it worked well there.

@d-healey
I now get another error while running the synth: Interface:! Line 16, column 23: Unknown function 'setAttribute'
I also noticed that every filter type is written twice.

@d-healey
it doesn't seem to work. here's a screenshot. Is the processor ID the underlined parameter?

@d-healey
I added a reference to the comboBox, but i don't know how to assigne the control callback you talk about. Here's what i got:

 const var filter = Content.getComponent("MAIN FILTER");
 const var comboBox = Content.getComponent("FilterType");
 const var modes = Engine.getFilterModeList();
 
 const var myFilters = [modes.LowPass, modes.HighPass, modes.BandPass];
 
 comboBox.addItem("LowPass");
 comboBox.addItem("HighPass");
 comboBox.addItem("BandPass");
 
 inline function onComboBoxControl(component, value)
 {
    local filterIndex = value - 1;
    filter.setAttribute(filter.Mode, myFilters[filterIndex]);
 }

Did i forget anything?

I go to the open recent xml tabe and select my project, which is in the case "3xOSC".

@d-healey
oh yes, i didn't noticed that. I added that line, but it still shows the error:

const var filter = Content.getComponent("MAIN FILTER");

I called the filter "MAIN FILTER".

Yes, i save the project. At least, i do a CTRL+Shift+S to save the xml. I don't know if there's something else to do.

Hi there,
i recently started using Hise to build a little synth. I wanted to add a combobox to switch between three filter modes (LP, BP and HP). my issue here is that i can't get the right filter type. i did some research and found a topic here that talks about the filters indexing.
I found a code snippet to select the right filter type (this thread: https://forum.hise.audio/post/5632). I wrote the same code in the interface script in the onControl tab, but i always get the same error, and i can't figure out what's wrong: "Error at inline function parsing: {SW50ZXJmYWNlfG9uQ29udHJvbCgpfDMyNHwxNnwy}".

Can someone tell me what i did wrong please? Here's my code:

/*function onControl(number, value)
{
	
}
 */
 
 const var modes = Engine.getFilterModeList();
 
 const var myFilters = [modes.LowPass, modes.HighPass, modes.BandPass];
 
 comboBox.addItem("LowPass");
 comboBox.addItem("HighPass");
 comboBox.addItem("BandPass");
 
 inline function onComboBoxControl(component, value)
 {
    local filterIndex = value - 1;
    filter.setAttribute(filter.Mode, myFilters[filterIndex]);
 }

Oh, and one more thing : does anyone know why my code is always erased when i reopen the project? i have to rewrite it everytime...

Thanks in advance!
