Switching stereo field.

[marcLab]

Hey, I want to switch my sampler stereo field with a btn.

const Sampler1 = Synth.getChildSynth("Sampler1");
var m1 = Synth.getRoutingMatrix("Sampler1");

const Button1 = Content.getComponent("Button1");
Button1.setControlCallback(stereo);

inline function stereo(component,value)
{
    if (value)
    {  
        m1.removeConnection(0, 1);
        m1.removeConnection(1, 0);
        
        m1.addConnection(0, 0);
        m1.addConnection(1, 1);
    }
    else
    {   
        m1.removeConnection(0, 0);
        m1.removeConnection(1, 1);
        
        m1.addConnection(0,1);
        m1.addConnection(1, 0);
    }
        
}

Is there a simpler way? Or I'm on the right path?

Thanks!

I think you're on the right path but I bet you can reduce the lines of code. value is always going to be a 1 or a 0, and the only numbers you are using are 1s and 0s so I'm sure there is a saving to be made :)

[marcLab]

@d-healey True that! Optimization!

Thanks @d-healey

[marcLab]

@d-healey

inline function stereo(component,value)
{ 
   var inv = 1-value;
   
   m1.addConnection(value, value); // L
   m1.addConnection(inv, inv); // R
   
   if (!value)
   {
          m1.addConnection(value, inv); // L
          m1.addConnection(inv, value); // R
   }


}

How about this for optimization :) ?

[d.healey]

@marcLab I think you can do better. I don't think you need the if statement at all.

[Christoph Hart]

Making inv local will be the best optimisation.

[marcLab]

@d-healey damn, my brain hurts a little bit..

[d.healey]

Don't you still need to remove the old connection?

[ustk]

@marcLab something is telling me that inv and !value might be equivalent

[marcLab]

@d-healey did the test, they seem to change when only calling .addConnection

[marcLab]

@d-healey just can't figure out how to arrive at only 2 lines of code

.addConnection(0,0) // L -> L
.addConnection(1,1) // R -> R

OR

.addConnection(0,1) // L -> R
.addConnection(1,0) // R -> L

With juggling with my value (0 or 1) without the if statement.

inline function onstereoFieldControl(component,value)
    { 
        local index = btnStereo.indexOf(component);
        
        // L->L R->R
        samplerMatrix[index].addConnection(value, value); 
        samplerMatrix[index].addConnection(!value, !value); 
    
        // L->R R->L
        if (!value)
        {
            samplerMatrix[index].addConnection(value, !value); 
            samplerMatrix[index].addConnection(!value, value); 
        }
        
    }

@marcLab Index has magically appeared, do you have more than one stereo button? And do you have a snippet?

[marcLab]

@d-healey yeah index because I have 6 btn for 6 different samplers :p, but this part is working :)

I'm just trying to reduce the number of lines. For being full optimal.

[d.healey]

@marcLab

I'm just trying to reduce the number of lines. For being full optimal.

Give me a simple snippet with a single sampler and routing matrix etc and I'll see what I can do.

The number of lines doesn't always make much difference to the performance but it can make a different to maintenance, reuse, and debugging.

Trying to be PROFESSIONAL :P

[d.healey]

inline function onstereoFieldControl(component, value)
{
    local index = btnStereo.indexOf(component);

    samplerMatrix[index].addConnection(value, value - 1 * value);
    samplerMatrix[index].addConnection(!value, !value + 1 * value);
}

@d-healey damn..let me try this!

@d-healey You little jokester

In my experience it also doesn‘t make sense going into full-riddle mode and condensing the functionality down to the least amount of characters because you will come back in a few months and think „what lunatic has written this“.

But it‘s a fun excercise...
