The PolySix has a linear DAC for note selection, and a single exponential
converter for all six voices to convert the linear DAC voltage to an exponential one.
If all six voices are off, then it could be that the exponential converter is a little off.
But it's somewhat tricky to adjust, so maybe better to just leave it as is, or adjust the
voice tunings instead. Hard to say which is off without measuring voltages for various keys.
