If you are hearing 6 different notes then your synth voices are
definately out of tune. There is a good link on the web about how
to tune it - usually best with a chromatic tuner and throw the synth
into test mode so you get a flat wave to tune to. It is a pain in
the ass to tune it properly but I threw mine completely out of whack
and actually made it better than when I bought it! Good luck.
