Kawai Synthesizers

Hello from Italy,

I'm new here and I subscribed to this group because I have a K1.

Unfortunately I have a problem with it.

When I try to edit a patch (tried only with "Multi" since I need a
patch for sequencing) the values of the parameters continue to change
by themselves without me having touched a single button.

If, for example, I try to modify the name of the patch I see the
selected letter randomly change even if I haven't yet touched the "+"
or "-" buttons. The continue their ballet even if I push the buttons.
So it's impossibile to select a particular value.

Same happens with any other parameter.

Any clue?

I haven't changed the battery in 15 years but the memory banks are
still there and this should not affect the unit when is turned on. Or not?

Thanks for any help!
