Adam from Copilot FX talked about his upcoming wobble filter a little while ago, but now there's a prototype and a
video preview.
It's a filter (not sure if it's low pass or band pass) with a pitch-tracking lfo -- higher notes = faster lfo speed. From the video you can make out volume, balance, range and trk (tracking?) controls. There is a key input on the side. Hopefully Adam will post what all of the knobs do soon.
