For some unknown reason, the Tempo wheel on my KN7 is not registering correctly. When I turn it up, it will sometimes go down before going up. Sometimes it goes in the opposite direction and sometimes it doesn't move. I do get there eventually, but as you can imagine, it is very aggravating. Also the LED no longer lights up. Any suggestions?

Whilst posting, has anyone heard of "The Kiss Waltz" and if so, can you tell me where to get it please. (yet another tune not in my library of songs) I've tried the net, without success.

Thanks!
