Hi Jules,

In the default&nbsp;MidiKeyboardComponent, the name of the keys seems to be left shifted. Running the JuceDemoPlugin, you can easily check that when pressing the C4 key, a C5 is actually heard. That is taking the A4 \<=\> 440 Hz convention.

Have a nice week-end,

&nbsp;

Sirdouille.

This is all explained in MidiKeyboardComponent:

```
/** This sets the octave number which is shown as the octave number for middle C.
        This affects only the default implementation of getWhiteNoteText(), which
        passes this octave number to MidiMessage::getMidiNoteName() in order to
        get the note text. See MidiMessage::getMidiNoteName() for more info about
        the parameter.
        By default this value is set to 3.
        @see getOctaveForMiddleC
    */
    void setOctaveForMiddleC (int octaveNumForMiddleC);
```
