Get Root Note

[DanH]

@d-healey good point re needing the timer if you can trigger a callback when the file is loaded (assuming the root note is instantly assigned upon loading)

[MikeB]

@DanH In my plug-in, the user can select the desired sample from 100 by means of a knob, and this four times for four AudioLoopPlayers.
A new sample is loaded with each scrolled value.
So I can scroll through the samples in 1 second with the mouse wheel.

If I set a timer here, it won't follow - I think.

[DanH]

@MikeB well if you already have a callback for loading samples (via your knob) can you not get the value of the root note and update the ui control in the knob callback?

[d.healey]

@MikeB Do what DanH says, just pull the value inside your sample selector's callback.

Knob1.setValue(AudioLoopPlayer1.getAttribute(AudioLoopPlayer1.RootNote));

@DanH I tried the loading callback but unforuntately it doesn't trigger with the audio loop player.

[MikeB]

@DanH Go to the beginning of the entry.
We were already here. That was the first and actually sensible thought, but it doesn't work. Or at least I (beginner) and David (Jedi Knight) can't solve it.

[DanH]

@MikeB snippet?

[d.healey]

@MikeB It does (should) work. But your original post didn't explain what you were trying to do :p This is the first mention we've had of a sample selector on your UI. Post a snippet with that.

[DanH]

@d-healey @MikeB You've highlighted a good point here Mike, a callback upon loading an audio file in the audio loop player would be useful, if only to update the root note ui control, because otherwise the user might think the root note on the ui is the actual root note, which in many cases it isn't @Christoph-Hart

It's caught me out a few time for sure

[MikeB]

@d-healey it works.

Thanks guys - solved - now I have only 1.234 problems until the completion of my first PlugIn :-)
It will - day by day

//Start Knob-SampleSelector----------------------------------------------------------------------------------------------------------------------
inline function onSampleSelector_Knob1Control(component, value){
	VariationID = parseInt(value-1);		
	//Console.print("Variation" + "{PROJECT_FOLDER}"+Instrument[InstrumentID]+"/"+Sample[VariationID]);
   Synth.getAudioSampleProcessor("Audio Loop Player1").setFile("{PROJECT_FOLDER}"+Instrument[InstrumentID]+"/"+Sample[VariationID]);   
	knb_Root.setValue(AudioLoopPlayer1.getAttribute(AudioLoopPlayer1.RootNote));
	knb_Root.changed();
};
Content.getComponent("SampleSelector_Knob1").setControlCallback(onSampleSelector_Knob1Control);
//End -------------------------------------------------------------------------------------------------------------------------------------- 

[d.healey]

@DanH I think it would be sensible if it used the loading callback that we already have.

[MikeB]

It works like this in both directions now.

1. when changing the sample, the RootNote of the sample is displayed.
2. if I change the value of the knob, it is played with a new root note.

Wonderful

inline function onknb_RootControl(component, value)
{	
if(value)
AudioLoopPlayer1.setAttribute(AudioLoopPlayer1.RootNote, value);
};

Content.getComponent("knb_Root").setControlCallback(onknb_RootControl);

[d.healey]

@MikeB You don't the if (value) part.

[MikeB]

Next challenge in this topic!

Is there already a snippet (or 2 lines of code) with the definition or the conversion of the note numbers into notes e.g. 60 = C3 or C4 as the case may be?

So that the root note number is no longer displayed here (60) but the actual note C3.

@MikeB

Engine.getMidiNoteName(midinotenumber);

[MikeB]

@ulrik That's simple - isn't there something more complicated?

[d.healey]

@MikeB said in Get Root Note:

isn't there something more complicated?

inline function midiNumberToName(n)
{
	local notes = ['C', 'C#', 'D', 'D#', 'E', 'F', 'F#', 'G', 'G#', 'A', 'A#', 'B'];
        return notes[n % 12] + Math.round((n / 12) - 2);
}

@MikeBDo You Have A Snippet For Study On This Usage?

[d.healey]

Actually I think my solution is better than HISE's :p This is the JUCE function that HISE is calling. Mine doesn't have as many options though.

String MidiMessage::getMidiNoteName (int note, bool useSharps, bool includeOctaveNumber, int octaveNumForMiddleC)
{
    static const char* const sharpNoteNames[] = { "C", "C#", "D", "D#", "E", "F", "F#", "G", "G#", "A", "A#", "B" };
    static const char* const flatNoteNames[]  = { "C", "Db", "D", "Eb", "E", "F", "Gb", "G", "Ab", "A", "Bb", "B" };

    if (isPositiveAndBelow (note, 128))
    {
        String s (useSharps ? sharpNoteNames[note % 12]
                            : flatNoteNames [note % 12]);

        if (includeOctaveNumber)
            s << (note / 12 + (octaveNumForMiddleC - 5));

        return s;
    }

    return {};
}

@d-healey Haha...yes your's is shorter at least, but you don't get flatmates
