Discussion about the Korg PolySix synthesizer

Ooh, just seeing that name makes me cringe. Was that a bit of your sadistic
side creeping through to specify a Varta battery? And I think you meant the
6032101501 not 6032401501. I hope nobody is considering a soldered battery
;)

Oh and just one other thing? The CR2032 battery is in the holder upside
down! This might be down to the way you have orientated the holder, but
traditionally + should face skywards. The right battery for the clone is
this one here:

http://uk.farnell.com/varta/6032401501/cell-coin-pcb-3v/dp/249877?Ntt=249877

Not that this affects your calibration, but worth mentioning all the same!

Cheers,
andy
