I'm out of LFOs, how can I put vibrato on my synth line in Ableton Live?

Question

I'm adding a synthesizer line to a recording I'm working with. I've gotten a nice sound using Ableton's Operator FM synthesizer, and I'd like to add some vibrato to it. Generally, this is done by using an LFO tied to oscillator pitch, and varying the intensity of it over time.

The problem I've run into is that Operator only has one LFO, and I've already used it as part of the design of the sound. It's not available for pitch modulation.

Is there another way that I can achieve this vibrato sound, perhaps in post production? It doesn't need to be played realtime, I just need to get a finished recording.

I'm using Ableton Live as my recording environment, but solutions using other tools are certainly welcome.

Answer 1

It should be a fairly straightforward DSP effect, if you're happy to do it in the mixdown. Some chorus and rotating speaker effects can also be wound back until they're just vibrato.

Answer 2

There are also MIDI LFO plugins which you could link to your instrument's pitch. Can't really think of any off the top of my head since I've never had the need to use them, but some googling will probably find you a good one.
