A way to make preset up and down buttons? (SOLVED)

[ulrik]

@SteveRiggs the code I showed is for a comboBox and I guess it will not work for a presetmanager, I guess they work different.
I just wanted to show you how the way was setup for changing presets in a cmb, then you have to see if it could be applied to a presetmanager.
I think there is examples, of how to setup a preset preview and next buttons, in Hise source code... I will check

[ulrik]

@SteveRiggs check this BasicSynth example:
https://github.com/christophhart/hise_tutorial/tree/master/BasicSynth

[ulrik]

@SteveRiggs you've forgotten to declare the cmb, paste this line in your initCallback

const var scalesCmb = Content.getComponent("scalesCmb");

Then the cmb will work :)

About the "count" variabel, in my code it will dynamically count how many presets there is inside the cmb, so to answer you question, yes it has to be the exact number of presets.

Ah. I did wonder why that wasn't there. I just copied and pasted the code exactly as it was to test it quick. My bad.

check this BasicSynth example:

I just check this example but it doesn't include preset up and down buttons. I found one in the music box tutorial but that looks as if its all json stuff which I don't really understand :( It json even still being used?

I was hoping to just make 2 buttons and add them into my existing projects and somehow link them to the preset browser to switch previous to next.

I'm wondering if these parts below from the customUserPresets tutorial can be picked apart and applied somehow? I can see in there that a list can be created automatically from the user presets, but they're loaded into a viewport then. Trying to work out a way.....

// This gets a list of all available user presets
const var list = Engine.getUserPresetList();

/** removes the directory names from the path. */
inline function getPresetName(relativePath)
{
    local l = relativePath.split("/");
    
    if(l.length == 3)
        return l[2];
        
    return "";
}

const var prettyList = [];
prettyList.reserve(list.length);

// Copy the preset names without the paths into a new array
for(i in list) prettyList.push(getPresetName(i));


// Load the pretty names into a viewport list
const var PresetListSelector = Content.getComponent("PresetListSelector");
PresetListSelector.set("items", prettyList.join("\n"));


inline function onPresetListSelectorControl(component, value)
{
    // Grab the preset name from the array and load it.
	Engine.loadUserPreset(list[value]);
    
};

PresetListSelector.setControlCallback(onPresetListSelectorControl);

Just add two buttons and put the loadNextPreset and loadPreviousPreset functions in their respective callbacks.

@SteveRiggs what Dave says...

like this(ish) where I have a button called myPresetName to display the preset name:

const var myPresetName = Content.getComponent("myPresetName");

inline function onNextUserPresetControl(component, value)
{
	//next preset.

	Engine.loadNextUserPreset(false);
	myPresetName.set("text", Engine.getCurrentUserPresetName());

};

Content.getComponent("NextUserPreset").setControlCallback(onNextUserPresetControl);


inline function onPrevUserPresetControl(component, value)
{
	//prev preset

	Engine.loadPreviousUserPreset(false) ;
	myPresetName.set("text", Engine.getCurrentUserPresetName());

};

Content.getComponent("PrevUserPreset").setControlCallback(onPrevUserPresetControl);

@Lindon @d-healey

Cheers fellas. I just tried this way but HISE instantly crashes as soon as I hit compile.

Content.getComponent("NextBtn").setControlCallback(onNextBtnControl);

inline function onNextBtnControl(component, value)
{
     Engine.loadNextUserPreset(false);
};


Content.getComponent("PrevBtn").setControlCallback(onPrevBtnControl);

inline function onPrevBtnControl(component, value)
{
     Engine.loadPreviousUserPreset(false);
};

[SteveRiggs]

@Lindon The same crash happens as soon as I hit compile on your code as well

[SteveRiggs]

@Lindon @d-healey @ulrik

Snippet here but it wont let me compile it. HISE just closes as soon as I push compile :(

Why have you set it to false, it should be set to true if you want it to load next or previous preset I think.

[Lindon]

@ulrik please read the documentation.....BEFORE you comment (yeah I know I do that too sometimes - silly me)

false here is (bool stayInDirectory) not do or not do....

[d.healey]

@ulrik That parameter determines if it stays within the folder when loading the next/previous preset.

[Lindon]

@d-healey ha! beat you to it.

[d.healey]

@SteveRiggs That snippet won't even load for me, HISE crashes instantly.

@d-healey ha! beat you to it.

I'm glad it makes you so happy :)

[Lindon]

@SteveRiggs <-- your snippet is crashing HISE so something else is broken bad in there.

-- oh look Dave beat me to it <rats>

[Lindon]

@d-healey yeah I'm a trivial person really....

Sorry ---getting us off topic....its been a long day...

[Christoph Hart]

My guess is that saveInPreset is not false for the button so that loading a user preset triggers the callback again and you get an endless loop.

[ulrik]

@Lindon sorry, I was to fast and stupid...🤭

[ulrik]

@d-healey thank you, I think I should stay out of this kind of discussions...🤭
