This update resolves an issue and provides several new features.

**Issues resolved:**

 - Added a security on *Program Change* or MIDI channel change (which formerly required only pressing +/-), so that they cannot be triggered inadvertently anymore. Now, holding the Aodyo key is necessary in order to activate these functions.

**New features:**

 - The Diagnostic screen now displays the state of upper keys.
 - Added new fingerings besides the original recorder: clarinet, flute, saxophone, oboe, EVI, hulusi, and whistle.
 - The whistle fingering behaves as a 6-holed flute, with a *sharp* key under the left pinky, and a *flat* key under the right pinky. We propose 36 variations of the fingering that follow musical modes (e.g., ionian, dorian…).
 - Added a second advanced settings screen that can be accessed by selecting `MENU 1` in the advanced settings and by pressing +/-. With this screen, you can setup:
	 - a fixed velocity value (when playing a MIDI note);
	 - the activation of a dynamic velocity mode (where MIDI note velocity is derived from breath level);
	 - the *Control Change* number of MIDI messages send using the slider;
	 - and the breath sensor calibration (cf. user guide).
