modulate pitch of individual oscillators?

[guarachiguaro]

Hi there,
I have the RME.
does anyone know if there's a way to modulate the pitch of only one oscillator? I know that the frequency of the oscs are a destination in the pot mapping section but the sources are things like filter attack/amt etc and I want a cyclical modulation like an lfo; specifically, I want to modulate osc 2 while synced to osc1 to get the timbre of the sync change as I sweep the pitch of osc 2 while osc 1 is stationary. It would also be useful to modulate pitch over a droning osc1. I dont have the input expander. I'm thinking it might only be possible with the expander and using an lfo input into mod 1 or 2?
thanks for your help in advance

In the mod buss controls you can send Lfo to OSC 2, without pot mapping.

Can't believe I missed that! thanks for pointing it out
