      Hey!

      Let’s say we got an oscillator (with sig2mod and peak):

      osc

      If you lower the gain, then the oscillation gets closer to the center line (middle), I’m wondering how you could make it so that the center line could get moved, such that we could have a low gain/depth of the modulation while only moving through high frequencies. Any ideas?

      Thanks!

        @Casmat If I understood whant you want, use a Math.Add node and change it's range to make it bipolar. You'll have to adjust the values :

          Er I think you are confusing gain and frequency... gain is "the amount in the vertical axis" - frequency is the "distance between peaks"

            @Casmat are you trying to imitate a DC offset? Not sure how that would work and what that would achieve. But if you're trying to use your Osc as an LFO source and change which range of your target is being modulated, you'd need to change the "middle position" of your target and use the amplitude of your Osc to determine the range. I think that's the easiest way. Some LFO plugins have built-in offset which is very handy, but I'm not sure how this could be achieved within scriptnode.

                @alhug @Lindon @Matt_SF Yup, dc offset is what I'm thinking off! And yeah, I'm trying to modulate a phase delay node such that certain areas only become modulated, like @alhug said

                  @alhug @Lindon @Matt_SF Thanks guys for your help, didn't think it was this easy haha, might need @Matt_SF to teach me how to use math nodes more

                    @Casmat @Matt_SF haha I'd take that Math master class too. I'm looking at them thinking "why are there so many?"
