Like a drumpad



  • Hi

    i would like to add to an image (pad) a simple sound from the sampler (note number 60)
    and to an other image the note 61.
    how can i do that?

    Thanks.

    This should get you going.

    
    // Store the event id of the generated note for the note on.
    // For a 4x4 Drumpad, use an array.
    reg b1EventId = -1;
    
    // Use a filmstrip to skin this button
    const var Button1 = Content.getComponent("Button1");
    
    // Make it momentary so that if you release the mouse, it will send a note off message
    Button1.set("isMomentary", true);
    
    // Make it non-persistent so that it won't get saved in presets and called on initialisation
    Button1.set("saveInPreset", false);
    
    function onNoteOn()
    {
        // This makes the button go down if you play a MIDI note
        if(Message.getNoteNumber() == 60)
            Button1.setValue(true);
    }
    function onNoteOff()
    {
        if(Message.getNoteNumber() == 60)
            Button1.setValue(false);
    }
    function onController()
    {
    	
    }
    function onTimer()
    {
    	
    }
    function onControl(number, value)
    {
        // Button press
        if(value)
    	// Play a C4 and store the event id for the note off
            b1EventId = Synth.playNote(60, 127);
        else
            // Use the event id to kill the note when you release the button
            Synth.noteOffByEventId(b1EventId);
    	
    }
    


  • "// For a 4x4 Drumpad, use an array."

    i think my problem is here.
    tried with 2 Pads. Midi works but click on button give the same note (and sound) for the twice buttons...



  • try to setup the array, but i can't. i lost all of my hairs, putting out one by one ...going crazy ...

    read all about array in this site (and elsewhere) but nothing works...

    1. Have you changed the note number from 60 to the other note?
    2. Have you changed the onControl callback to an actual switch statement (I skipped it in this simple example, but if you don't do it with more than one control then the onControl callback gets fired multiple times.



  • administrators

    Yes, the onControl callback is fired for every control and you have to branch it to implement each specific behaviour either using a switch statement or a large if...else structure (which is far more inefficient though).



  • ok, in OnControl i did:

    	{
    		case Button1:
    		{
    // Button press
        if(value)
    	// Play a C4 and store the event id for the note off
            b1EventId = Synth.playNote(48, 127);
        else
            // Use the event id to kill the note when you release the button
            Synth.noteOffByEventId(b1EventId);
            break;
    		}
    		case Button2:
    		{
    // Button press
        if(value)
    	// Play a C4 and store the event id for the note off
            b1EventId = Synth.playNote(52, 127);
        else
            // Use the event id to kill the note when you release the button
            Synth.noteOffByEventId(b1EventId);
            break;
    		}
    	}
    

    it works !

    but i kept just your: reg b1EventId = -1; in OnInit (without array)

    you wrote that we must create array ... (?)



  • ok,
    for Chris (and other users) i did a simple project with 3 buttons. Notes are 48,50 and 52 (C1, D1 and E1)
    you must change it in the OnNoteOn, OnnoteOff and OnControl to your desired note 😉

    Thanks staiff. I've updated your example to include a few fixes and best practices:

    • used the array method for storing the event IDs (your script will behave weird when pressing more than one note / button at once).
    • using the switch statement in the note callbacks for improved efficiency. Try to use switch as much as possible especially in the high performance callbacks.
    • removed some comments that were duplicated for no reason.
