A/B comparison

Dan Korneff

I spot an error in my function. in the second half idx is undefined.

    //recall state if not pushed
    if(!value)
    {
        local idx = AB_Array.indexOf(component);
        A_B.restoreState(idx);
    }

it should be

    //recall state if not pushed
    if(!value)
    {
        local idx = AB_Array.indexOf(component);
        A_B.restoreState(A_B_Storage[idx]);
    }

but changing to this value causes an instant crash.

@dustbro yeah I have A/B running in my synth - export and restore are not any use to me - as I want to be able to morph states a-to-B and to include/exclude voices in that process.. so it's all hand built.

Any hints on the method you used?

Lindon

@dustbro see the post here from April 9th

Dan Korneff

@Lindon Are you using

Content.storeAllControlsAsPreset()

or

Engine.dumpAsJSON()

no. neither.

I have a two array-dimensional array of "sound affecting controls"(lets call them slots) - and a button (in stateA or stateB).

I save the array in the preset(panel.data) and depending on the button state I load one or other dimension.

This allows me to :

have a morph slider so I can move between slots
Include or exclude any set of controls from this morph
on preset load I can overwrite the loaded preset with these values if I wish

So I have a 4-voice synth - the user can morph between Slot A and B - and include or exclude any voice, and they can include or exclude any voice from a preset load.

@Lindon Got it!

Can I get some extra eyes on this AB script? This is a simplified script with 2 knobs controlling an EQ.
If I comment out Compare_Elements_Array[i].changed(); the knobs store/recall as expected but module doesn't update (also expected). With .changed() left in, one knob works, and the other stops updating.
I can't see why.

The full version of this script is getting Time Out errors on the for() loops and crashing HISE... yay!

@dustbro I don't fully understand why but calling changed() at the end works:

inline function onCompareControl(component, value)
{
	if(!value)
    {
        for(i=0; i<Compare_Elements_Array.length; i++)
        {
            Compare_A[i] = Compare_Elements_Array[i].getValue();
            Compare_Elements_Array[i].setValue(Compare_B[i]);
        }
    }
    
    if(value)
    {
        for(i=0; i<Compare_Elements_Array.length; i++)
        {
            Compare_B[i] = Compare_Elements_Array[i].getValue();
            Compare_Elements_Array[i].setValue(Compare_A[i]);
        }
    }
    
    for (comp in Compare_Elements_Array) comp.changed();
};

Content.getComponent("Compare").setControlCallback(onCompareControl);

@dustbro - what @ustk said - the only way I get this sort of thing to work is to make all the value changes then outside that loop do the changed() element

Dan Korneff

@ustk said in A/B comparison:

for (comp in Compare_Elements_Array) comp.changed();
