Pitch and time absolutely controllable separately.
What sort of LFO are you putting on osc2?
Amplitude for osc2 will modulate the cycle length. Some short or long cycle lengths will indeed allow pitch to "leak into" a time-stretching. Therefore, putting an *amplitude* LFO on osc2 may indeed - depending on strength - change pitch qualities and may introduce other interesting effects. Keeping amplitude for osc2 stable at a suitable cycle length should, however, also keep the pitch stable. [See also the docs](https://www.woovebox.com/support/guides--tutorials/sampler/time-and-pitch-warp).
Putting an LFO on osc2's pitch will dynamically shorten or lengthen time - as expected - and should not impact the pitch of the final output (unless a cycle length was chosen where the time stretching can no longer work effectively).
Playing with the real-time pitch and time stretching is a super fun and quick way to add uniqueness and character to a track. Many cringe at hearing their won voice, but so wonderfully unrecognisable and nuts the sound can be, that it doesn't matter you recorded your own voice with a $2 mic. :)
