Activating/Deactivating a GUI Button via MIDI Keys in HISE?

[lijas90]

Hi, I’d like a button to turn on and off when I press certain keys. I tried this in the Script Processor but it doesn’t work. Can anyone help me? Thanks a lot.

function onNoteOn()
{
    
    if (Message.getNoteNumber() == 47 || Message.getNoteNumber() == 48)
    {
        local value = btn1.getValue();
        btn1.setValue(1 - value);
    }
}

@lijas90 In what way does it not work?

That code looks good and works here.

I also made a more refined version for you

@d-healey Ok, now it works. Thanks. However, it only works when I press the physical key on the controller. Is there a way to make the button activate when a MIDI player is playing those notes? To simulate an instrument animation that triggers when the MIDI is played? Thanks.

@lijas90 Have you tested it in a daw? It should work

[lijas90]

@d-healey

I’ve tried it and it doesn’t work. Do I need to do it in a Script Processor inside the MIDI Processor in some specific way?

[lijas90]

@lijas90 Sorry, it does work.

[lijas90]

@lijas90 Thanks David!

[lijas90]

@d-healey How can I make the button activate only while the key is being pressed, and deactivate when the key is released? Thanks.

[d.healey]

@lijas90 In onNoteOn turn the button on, in onNoteOff turn the button off.

[lijas90]

@d-healey I’ve tried it like this but it doesn’t work; the button only deactivates when pressing it again, not when releasing the key. Thanks, my friend.

function onNoteOff()
{
local n = Message.getNoteNumber();
   
   if (ks.contains(n))
       btn1.setValue(0);
       
       

}

@lijas90 Post a snippet so I can see the full code

@d-healey Sorry, it works now. Thanks again, David
