Hi Dave,

have you even checked if the update was 1.6 successfully?

Here the description, can be displayed as the display of the release.

First Step:

Announcement of the installed version:
1. Switch off the keyboard.
2. Press in the SOUND GROUP the keys [PIANO] - [GUITAR] - [MALLET & ORCH PERC] and hold this during the turning on low-spirited.
3. Then after the turning on you see on the right below in the display the version number.
4. If the version number is same or even higher, as the offered here, an update is not necessary!
