Scriptnode Osc Freq to Note?

[Natan]

Hey folks
I Have this question, what should i connect to the freq knob so i can select a Note, instead of frequency?

Thanks

@Natan You'd need to script a conversion from note number to frequency.

@Natan or you can use control.midi and control.converternodes :

@Matt_SF @d-healey
@Christoph-Hart said in Freq to note (st + cents):

Basically its just the inversion of this formula from the JUCE method:

double MidiMessage::getMidiNoteInHertz (const int noteNumber, const double frequencyOfA) noexcept
{
    return frequencyOfA * std::pow (2.0, (noteNumber - 69) / 12.0);
}

I‘ll leave that here as excercise in basic math

Based on This, how can achieve a Knob, that changes the notes,
I just need a knob to change the Frequency Based on Notes in Scriptnode,
Maybe Math.expr, or Something?

[Matt_SF]

@Natan you can use a cable.expr node to enter this function. This node has a modulation slot which will change the destination parameter.
Use Math. Pow().

[Christoph Hart]

I think there's a converter mode for exactly this purpose already so you don't need the expr node.

Yes it is
