Like a drumpad

Christoph Hart

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...

staiff

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...

Christoph Hart

Have you changed the note number from 60 to the other note?
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.

staiff

yes: changed the note number for the 2 pads (because my notes was 48 &52 for testing)
no i just duplicate the OnControl Values.
the switch statement like in the multipages ? (http://forum.hise.audio/topic/499/multiple-page/17)

Christoph Hart

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).

staiff

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 ... (?)

staiff

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.

Thanks Christoph, Staiff working well now!

@staiff Hello, the garbled code shown here, can you please write a regular code? Because I also encountered the same problem, I refer to your code, button 1 and button 2 can trigger different sound samples, but button 3, button 4, button 5, trigger the same sound sample, how can Each button triggers a different sound sample?
Also, why do I add my own image to the button to display only half of the image? How can I display the full image?

@lixiaolong Everything seems to work fine for me using the hise snippet provided above.

lixiaolong

@Dalart Hello, thank you very much! Are you willing to share the code with me for reference? Only button 1 and button 2 can trigger different sound samples, and the sound samples of button 1 or button 2 are triggered from button 3.

Dalart

@lixiaolong Here ya go, I used @Christoph-Hart 's HISE snippet above and just added a few samples to it so you can see it working correctly. Hope this helps, just paying it forward for the help I've gotten from this forum :)
