Perfect OSC2 + OSC3 unison tuning

Post by Newmoog » Sun May 01, 2016 3:54 am

When setting OSC2 and OSC3 to 0 pitch deviation I can still hear a very light phasing effect on my Voyager. There seems to be no "absolute unison" point there. Maybe the waveform is not exactly the same causing some phasing, not sure. I don't really care much musically speaking, but can you guys please remember me if this is a knob resolution problem or would my unit require calibration?

Even if the oscs are perfectly matched frequency-wise, there's nothing to guarantee the phase relationship. They're free-running oscillators, and that's actually the point to get a fatter sound out of them. If you want sync, you can select that for 1-2 but not for 3.
