I didn't realize I had somehow changed the master tuning--- I haven't ever changed it before--
but it played consistently in its out of tune way.-- that is why I knew there was some way to adjust that--but didn't realize it was "under' the volume slider. I now see it was quickly mentioned in the manual but not that I understood at the time --
thank you so much. I play my Polaris a lot and I was sure there was some solution.
