Changing the filter mode from a ComboBox

[d.healey]

This was brought up some months ago. There is a mismatch between the indexes which I believe was caused by new filter types being added and Christoph trying to avoid causing backwards compatibility issues. The current work-around is to do it via a custom callback.

@d-healey ok so what are the values I need ot set, and where do I put this "custom callback"?

[Lindon]

@Lindon

Ok well I found this:

https://forum.hise.audio/topic/74/how-to-control-modules-with-scripts

Which is helpful, in some ways. It tells you how to set a value IF you know what the "magic numbers" are - sadly it is not uncommonly pretty poor at telling you how to find these magic numbers.

oit says this:

"But there is no need for magic numbers, there are several ways to obtain the index:

In the development tools area, there is a searchable list with all modules. You can right click on a module and a popup with all parameter names and their respective index should popup."

but of course the world moved on and there is no "searchable list" that I can find. In tools menus or in the UI...

So for those of you wanting to set the mode of a filter here's the code you will need:

const var yourFilterName= Synth.getEffect("yourFilterName");

inline function onButton1Control(component, value)
{
	//Add your custom logic here...
	yourFilterName.setAttribute(yourFilterName.Mode, <a magic number>);
};

Content.getComponent("Button1").setControlCallback(onButton1Control);

The magic numbers seem to be:

0 = Biquad LP
1 = Biquad HP
2 = Lo Shelf EQ
3 = Hi Shelf EQ
4 = Peak EQ
5 = Biquad LP Rez
6 =SVF LP
7 =SVF HP
8 =Moog LP
9 =1 Pole LP
10 =1 Pole HP
11 = not assigned
12 = SVF Notch
13 = SVF BP
14 = Allpass
15 = Ladder 4 Pole

-- who knows where Ring Mod is, anything above 15 seems to be unasigned , anything below 0 crashes HISE -- you were warned.

@Lindon Ringmod Filter is 17 ;)

@orange thanks mate - I tried 17 and it didnt seem to work - but clearly I didnt cause its working now...

const var list = Engine.getFilterModeList();

the object returned from this method contains all filter indexes as constants. You can use it in a combobox in conjunction with an array of string like this:

const var list = Engine.getFilterModeList();

const var myIndexes = [ list.LowPass, list.RingMod, list.Peak ];
const var myNames = ["Fnky VA LopazZ", "Ringmod", "Ultra clean super analog style peak PULTEC Simulation"];

Oh I was late getting back to this post tonight. Seems a solution has been provided. For reference though I will include a link to the related thread - https://forum.hise.audio/topic/877/filter-mode-dropdown-bug/6

[d.healey]

@Christoph-Hart It seems the getFilterModeList() function isn't working properly

This gives a no iterable type error.

const var indexes = Engine.getFilterModeList();

for (k in indexes)
{
    Console.print(k);
}

[Christoph Hart]

The object that is returned from this function is not a standard Javascript object, but a special object with read only properties.

I didn't add iterator support for it because it would defeat the entire purpose of the object which is selecting a few filter types that you want to show. Relying on the order and how many filter types I have added to HISE is the exactly why there is this object :)

[d.healey]

@Christoph-Hart Ah gotcha, I understand now.

i want assign Biquad Lp Rez & Biquad HP mono filter mode on button.
see my code :

Content.makeFrontInterface(600, 600);

const var list = Engine.getFilterModeList();

const var BqLPR = list.BiquadLpRez;
const var BqHP = list.BiquadHp;

const var Button1 = Content.addButton("Button1", BqLPR, BqHP);
    if (Button1 == 0)    
{
        Synth.getEffect(BqLPR);
   }
   else (Button1 == 1)  
{
     Synth.getEffect(BqHP);
}

const var Filter1 = Synth.getEffect("Filter1");

For now button switch with Biquad LP & Biquad HP (no Biquad LP Rez)
