Surely the memory is backed up by the normal AA batteries you can use to power the thing isn't it?

I had a similar problem - but overcome it by wiping each pattern and reseting the metronome and measure.  Then  I cleared all instruments and it worked.  I have connected an external battery pack as I don't want any battery leakage.  The patterns have remained.

I also discovered the kpr-77 service manual somewhere on this site too
