At the moment, I believe the only ways that Pulv can process the "audio in" signal is by applying (amplitude and filter) envelope control (triggered by notes in the notetrack) on top of this signal.
The effect I hope to achieve by this feature request is to be able to apply "vibrato" to the "audio in" signal. You can use the LFO to modulate the pitch of Osc 1, 2 and 3, would it be possible to be able to oscillate the pitch of the "audio in" signal using the same LFO? Perhaps there are more options for signal processing that I haven't mentioned, please comment if you have ideas.

Normally synths treat external input signals as another sound source in addition to their oscillators and pass it down the following stages in the signal path (mix, filter, amplifier). Since pitch modulation applies directly to oscillator frequency, it falls outside of controlling frequency of external audio. Therefore vibrato should be applied before. The chorus pedal can create vibrato on any signal at high depths.
