A/B comparison

This has been asked for a few times. Here is one solution I have found, although I haven't tried it in a real world project so there may be some unintended effects.

Originally I was thinking of exporting the state of the controls to a string and storing them in a panel but unfortunately HISE prevents us from getting a reference to the main interface from within the main interface script so that won't work.

The method I'm using instead is to export as a preset XML outside of the usual preset system (I think).

Actually it seems there is a problem with this method too, it only write the value the first time the state is exported. @Christoph-Hart is this intentional?

orange

@d-healey Very good starting point.
In A/B comparsion, There is an A to B copy button (so the user don't have to start a new preset from scratch, just continue from the A) and undo, redo options.

Fortune

This solution is not working properly? Anyone didn't implement it yet?

d.healey

Now that we have the ability to read/write JSON files I think that would probably be the direction to go in with this.

Lindon

@d-healey hmm, but that would mean writing to the JSON file every time the user changed a UI element no?

Given this is all transitory data - cant you just keep it all in an array? Or am I missing something obvious?

d.healey

@Lindon You'd only need to read/write the JSON when the A or B button is pressed. I'm sure there was some reason why we couldn't just store it in an array but right now I can't remember what that is... perhaps it is doable!

Lindon

@d-healey - maybe - but my thinking went like this:

on init

read all the GUI element values - store them in Array_A and Array_B

on ui change

store its value in Array_A (if A button = true) or store it in Array_B (if B button = true)

on button A

set everyone to Array_A values and issue .changed()

on Button B

set everyone to Array_B values and issue .changed()

Or (as I say) I may be missing the point here...

d.healey

@Lindon

on ui change
store its value in Array_A (if A button = true) or store it in Array_B (if B button = true)

This might add some unnecessary overhead and extra code. Why not just store all values in array A once when button B is pressed? I'm also thinking we could avoid using an array and use a base64string using MidiProcessor.exportState() although I don't know if this function can be used from within the MIDI processor that is being exported/restored.

Lindon

@d-healey sure that'd work too...

Dan Korneff

Has anyone explored this further? I'm experimenting with exportState() and restoreState() at the moment.

// initialize array with current loaded state

inline function A_B_Function(component, value)

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

        local idx = AB_Array.indexOf(component);
        A_B.restoreState(idx);
    }
	
};

for(abab in AB_Array) abab.setControlCallback(A_B_Function);

The exportState() appears to be working and I can store that value in an array, but restoreState() is questionable. At the moment, it only sets the master container volume to -100.

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.

Lindon

@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.

Dan Korneff

@Lindon said in A/B comparison:

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()

Lindon

@dustbro said in A/B comparison:

@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.

Dan Korneff

@Lindon Got it!

Dan Korneff

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!
