Simple Note Player (not Arpeggiator)

[hisefilo]

How can I do to do a note to be played based on tempo. Let's say C1 on quarters, D1 on half, F1 on triplets? Can't find anything related on forum!

[d.healey]

I've not done it but I would assume a combination of Timer Callback, one of the tempo functions such as Engine.getQuarterBeatsForMilliSecondsWithTempo(double milliSeconds, double bpm), and probably Engine.getHostBpm() or Engine.setHostBpm(double newTempo) as needed.

@d-healey Yes I was diving in API, but can't figure out yet.

[d.healey]

@hisefilo Get the BPM you want in milliseconds and set the timer interval. Then in the timer callback use Synth.playNote();

You can use a MidiPlayer and create this sequence by script.

Do we have documentation yet??

[hisefilo]

@dustbro Can't find anything. A simple snippet maybe? @Christoph-Hart

Also I'm trying to get this buttons light on and off on mouse click. But cant get it working. Any ideas guys?

const var BD = Content.getComponent("BD");

inline function onBDControl(component, value)
{
	Synth.playNote(36, 127);
	Message.delayEvent(5000);
	BD.setValue(0);
};

Content.getComponent("BD").setControlCallback(onBDControl);

These are the markdown files which will be rendered in the doc system (subject to HISE 3.0).

@Christoph-Hart Any chance you'll have a Tutorial posted for this feature? Im digging in tonight

By the way, the midi player sync is not working properly.

When I open a 4 bar midi loop, the loop plays 4 or 8 times faster.

I've noticed that too

@Steve-Mohican @ulrik
Do you guys have a snippit of how you're implementing the feature? Looking for some programming inspiration.

[Steve Mohican]

@dustbro For midi player I used drag and drop feature to load midi files. But every time I load different midi files, midi player began to so so speedy (as I mentioned above, 8 times faster). So I haven't got any special snippet yet, but I can share when I will.

[Christoph Hart]

Hmm works for me well in a project I am currently working on.

Can you send me the MIDI file, perhaps there is some metadata in my files that I am expecting to be standard, but are missing in yours?

[ulrik]

@Christoph-Hart here's a midi file that I use inside Hise, the original tempo is quarter note = 200bpm, but when I play it in Hise I have to set global tempo to half the tempo, 100bpm.

@dustbro I use it for demoing the sample library so the user can can chose one of many built in midi files to play, it looks like this:

inline function onDemoSongsControl(component, value)
{
    MIDIPlay.stop(0);
	DemoTimer.stopTimer();
	Engine.setHostBpm(-1);
    DemoSongs.set("items", DemoSongsArr.join("\n"));
    
    if(value < SongInfo.length)
    {
        MIDIPlay.setFile("{PROJECT_FOLDER}"+DemoSongsArr[value]+".mid", true, true);
        SongInfoPnl.set("visible", true);
        SongInfoLbl.set("text", SongInfo[value]);
        Engine.setHostBpm(DemoSongsTempi[value]);
        MIDIPlay.play(50000);
        DemoTimer.startTimer(7000);
        DemoOnBtn.setValue(1);
    }
    else
    {
        SongInfoPnl.set("visible", false);
        DemoSongsPnl.set("visible", false);
        label7.set("enabled", false);
        DemoOnBtn.setValue(0);
    }
};

Content.getComponent("DemoSongs").setControlCallback(onDemoSongsControl);

[Christoph Hart]

Ah, thanks, it's what I thought, you're using a MIDI resolution of 480ppq, while I am expecting 960ppq, which I thought was standard.

Unfortunately fixing this is not as trivial as I hoped, I need to convert them manually if the resolution doesn't match (because internally I am doing everything in 960ppq).

[ulrik]

@Christoph-Hart I see, is there a command to apply in the code when loading a midi file, that will half the tempo of the midi file, like "Engine.setHostBpm("midiFile.getResolution() * 2)"...
I mean "Engine.setHostBpm("midiFile.getTempo() / 2)". or something?
