Piano 2 Patches keep changing automatically HELP

[Vantropolis1]

Recently my Nord piano 2 started changing patches automatically. I change from grand to wurlitzer it immediately changes sound back to grand....or electric or what ever is first in that group. Wont let me change from a grand to clav or rhodes or upright without reverting right back...but with an astrick next to the patch name.

Have you plugged in the USB cable or the MIDI cable? If you have, the first thing to do when troubleshooting would be to remove any USB or MIDI cables.

Welcome to the forum, by the way!

Hi and welcome!
I think the asterisk indicates that the Nord thinks the patch has been edited... This might be caused by a key being stuck - look for any keys not in their fully up position. Alternatively, it might be an electrical fault causing the Nord to detect incorrect key presses. Hopefully, it's just a mechanical issue that you can resolve yourself.
Let us know if you find anything.
