Button play midi note?

[maurodechen]

Hello everyone!
Can I assign a Button or a Image to play a midi note with mouse left click?

I'm sorry if the answer was in my face. I really can't find something about this!

[d.healey]

Yup

@d-healey Perfect. Thank you!

[maurodechen]

@d-healey My sampler is set to Oneshot. It plays normal on the keyboard but using this code I need to hold the "Button1" to play the entire sample.

If I cut the "else" part it will play the note forever so probably not the best idea.

Any tips?

inline function onButton1Control(component, value)
{
    if (value)
	    Synth.playNote(80, 56);
	else
	    Engine.allNotesOff();
};

Content.getComponent("Button1").setControlCallback(onButton1Control);

@maurodechen What do you want it to do?

[maurodechen]

@d-healey The button is working in "normal" playback mode. I want it to play oneshot mode like the sampler.

[d.healey]

@maurodechen But in oneshot mode the sample will continue to play until the end which you already achieved by removing the else... or am I misunderstanding what oneshot mode is?

[maurodechen]

@d-healey Yes. If I remove the else it will play oneshot. But the midi note will keep playing infinitely even if I release the mouse button. The Sine Wave Generator confirmed that

[d.healey]

Oh I get it.

Try this code. It turns off the old note before playing a new one. Of course the last note won't be turned off though. If you want to to turn the last note off I think you'd need a timer that checks to see what the voice count is and turns the MIDI note off when the voice count is 0.

const var ids = Engine.createMidiList();

inline function onButton1Control(component, value)
{
    local noteNumber = 60;
    
    if (value)
    {
        //Turn off old note
        if (ids.getValue(noteNumber) != -1)
            Synth.noteOffByEventId(ids.getValue(noteNumber));
        
        //Play new note
        ids.setValue(noteNumber, Synth.playNote(noteNumber, 60));
    }	    
};

Content.getComponent("Button1").setControlCallback(onButton1Control);

[maurodechen]

@d-healey Actually the voice count seems like an excellent idea!

I found "getNumVoices" in the ApiCollection.

A function that keeps counting the voices and when it's 0:
Engine.allNotesOff();

I'm asking because I understand the logic but I'm a little lost in the coding yet.
You think that's the direction?

Something like this certainly sounds better than a never ending midi note even if there's no sound being produced.

[d.healey]

Yeah that's what I was thinking. You'll need to use the timer callback too. However I wonder if there is something automatically built in to HISE that turns notes off when the samples they trigger reach the end. I'm not sure how to test this but @Christoph-Hart will know.

@maurodechen @d-healey I never did it with samples length, but in one of my projects I am using the sum of different time parameter of an AHDSR (summing the get.attribute for attack, hold, decay...)
If it can help...

time = Synth1AHDSREnvelope.getAttribute(2) + Synth1AHDSREnvelope.getAttribute(4) + Synth1AHDSREnvelope.getAttribute(5);
        samples = Engine.getSamplesForMilliSeconds(time);
        
        noteID = Synth.addNoteOn(ch, noteNb, noteVel, 0);
        Message.makeArtificial();
        Synth.noteOffDelayedByEventId(noteID, samples);

[maurodechen]

@ustk Yes. Maybe this last line is what I need. Gonna try to code something! Thanks!
