Hi All,

I've posted this problem on another forum with no luck finding solution.

Problem is as follows. I setup waveform on osc 1 and set osc 2 semitone knob and fine tune to center position. KBD track is on and SYNC is off. All LFO and modulation is off. Turn mix all the way counter clock wise so only osc 1 is heard. If I play a G# for example and look at spectrum analyzer I see a fundamental of 204Hz as expected. Turn mix knob all the way clockwise so only osc 2 is heard. Play the same G# note now I get a fundamental on spectrum analyzer of 409Hz. This is B 15 semitones above osc 1. It would appear osc 2 is out of tune relative to osc 1. It is possible to tune osc 2 to the correct pitch using semitones and fine tune knobs.

Has anyone seen this behavior before or know what the cause is. Any help would be very much appreciated.

Thanks
