Just Bought THE SOURCE - Out of Tune -

I am new to the analog synth world (tuning!) I am used to my MS2000 - -

The Keys are very out of tune - G is C etc etc – the problem is that octave one is worse than 2, actually the middle of the keyboard is ok - however the lower and higher ends are out of tune. Any suggestions on tuning here? The Fine tune does not adjust the pitch enough.

Is there an internal tuning control that I am not aware of?
Should I have it serviced?

I am familiar with electronics, and I am not afraid to crack her opened, but I could use some advice here.

Thanks

I think your Source needs calibration.

BTW: are both oscillators off pitch by the same amount? If yes, then it is a bit strange.

Anyone know how to do this properly?
