This is version found initially in the new Sylphyo with internal sounds.
It introduces direct USB-MIDI connection, breath filtering, and several modifications regarding the Saxophone fingering.

**Improvements:**

 - Changed the _Saxophone_ fingering, which is now much closer to the saxophone. The former version of the fingering can be found a bit further down the list, as _Saxophone (old)_.
 - Improved battery life estimation and display.≈
 - Program changes and volume are now remembered after a power cycle.
 - The pairing icon is now always displayed when the Sylphyo is connected to the wireless receiver. It is hidden when wireless has been disabled (for Sylphyo with sounds only).
 - Changed the granularity of some value selectors (e.g., volume quick setting, or breath _Range_) to facilitate operation.
 - Corrected a bug that would result in an ongoing note not being silenced when presented with the "low battery" screen.
- Handling of the new wireless system and of the internal synth (for Sylphyo with sounds only).

**New features:**

 - Your Sylphyo can now be used without the wireless receiver device. When directly connecting the Sylphyo to a USB host (computer, etc.), it is now recognized as a class-compliant USB-MIDI device.
 - Added a fingering variant called _Saxophone (alt)_, with the right pinky finger key being a low Eb key instead of a low C key.
 - Breath filtering (enabled by default after reset) smooths the breath control data sent by your Sylphyo without compromising reactivity and breathing techniques. If you severely restrict the air flow of your Sylphyo, you need it much less and might want to disable it. The _Filtering_ setting can be found in the _Breath_ section of the settings menu.
- Handling of the new wireless system and of the internal synth (for Sylphyo with sounds only).
