I just bought a used qs8 (ebay).  I have a test period and I'm trying to figure out if this is 
a decent instrument.  My wife plays the piano  well, I play the radio.  The upper 6 notes on 
the keyboard sound flat to us both when in the piano program group.  When in other groups
the notes don't sound flat.  Could a previous owner have adjusted the individual notes and 
if so how do I get back to the factory presets. 
One other question.  I seems that different keys have different loudness for the same level
of touch.  Is this normal, does the keyboard need cleaning, can this be fixed.  I would appreciate
any emails or postings.  Thanks very much.  JM
