Hi
Does anybody know, why the sawtooth waveform is not the same on LFO and normal Oscillators of the G2?

On Oscillators the sawtooth looks to upper right. That is the normal behaviour for an analog VCO (but the display on osc shows upper left).
On LFO it looks to upper left, which means it's inverted. Is that normal? And if it is, why?

The patch demonstrates it. Just use the switch to change the modulation source. I couldn't try the same on the old Nord Modular, just on G2.

Thanks, Gal

On the LFO it doesn't really matter as there is the invert control next to the output.

The only difference between LFO sawtooths and OSC sawtooths is that the OSCS are anti-aliased and run on four times the sample rate. There is no audible difference between a sawtooth and an inverted sawtooth, unless asymmetric distortion is applied afterwards, then it can differ a lot. But of course that is due to the asymmetry caused be the distortion and not a property of the sawtooth itself.
