Link Delay Times

[DanH]

Hi guys, could anyone recommend a script to link the L/R Delay times via a button, I was hoping to slot in the example from the HISE General UI (Link Sliders) but it doesn't appear to work! Here's my current script:

//DELAY LINK - NOT WORKING

reg i;

const var fx = [];
fx[0] = Synth.getEffect("Delay1");
fx[1] = Synth.getEffect("Delay1");

const var btnLink = Content.getComponent("DELAYLINK");

const var knobs = [];
knobs[0] = Content.getComponent("DELAYTIME_L");
knobs[1] = Content.getComponent("DELAYTIME_R");

knobs[0].setControlCallback(knobCB);
knobs[1].setControlCallback(knobCB);

inline function knobCB(control, value)
{
local idx = knobs.indexOf(control);

if (btnLink.getValue() == 0) // Controls not linked
{
    fx[idx].setAttribute(2, value);
    fx[idx].setAttribute(3, value);

}
else 
{
    for (i = 0; i < knobs.length; i++)
    {
        fx[i].setAttribute(2, value);
        fx[i].setAttribute(3, value);
        knobs[i].setValue(value);
    }
}

}

Many thanks in advance

//DELAY LINK - NOT WORKING
 
 reg i;    //<--- no need to declare this if its just used in a for loop
 
const var fx = [];  // <--- shouldn't set this to a const and then put something in it later.....
fx[0] = Synth.getEffect("Delay1");   // <-- like this
fx[1] = Synth.getEffect("Delay1");

const var btnLink = Content.getComponent("DELAYLINK");
 
const var knobs = [];    //<-- again not constant....
knobs[0] = Content.getComponent("DELAYTIME_L");
knobs[1] = Content.getComponent("DELAYTIME_R");

knobs[0].setControlCallback(knobCB);
knobs[1].setControlCallback(knobCB);
 
inline function knobCB(control, value)

    if (btnLink.getValue() == 0) // Controls not linked
    {
        fx[idx].setAttribute(2, value);   //<-- better using the constant names not the index numbers - more readable
        fx[idx].setAttribute(3, value);
    
    }else{
        for (i = 0; i < knobs.length; i++)
        {

            fx[i].setAttribute(3, value);
            knobs[i].setValue(value);    //<-- so you changed them but didnt ask them to do anything
            knobs[i].changed();  //<-- so add this line....

        }
    }
        
}

Many thanks in advance

@Lindon Thanks mate :)

So I've copied in your script and changed the 2 x 'const var' to just 'var' that you recommended... Should it be working? (It's not). Please let me know anything else I shld be doing...

[Lindon]

@DanH try debugging it....

add some Console.print statements to see what is working and what isnt...

you may find this is where at least some of your problems are:

fx[0] = Synth.getEffect("Delay1");   // <-- the first delay you want to change
fx[1] = Synth.getEffect("Delay1");     // <-- wot? the first delay again???

@Lindon Thanks for he help! So the two knobs were still linked to the delay parameters, once I removed it worked fine! Doh.

Just saw the updated message and if I remove the second 'fx[1]' line the knobs don't move together, so I've left it as was as seems to work that way.

Thanks again :)
