But you should be able to do that with any rompler with sawtooth waves. I'm not sure why it's making the "wobwob" during pitch bends. Maybe it's beating against itself and the delay is doing it for no other reason, I've had that happen before.
Try a two OSC patch on anything with sawtooth waves, maybe add in some pulse width modulation waves, in octaves. Filter mostly open, envelope attack and release set for a soft beginning and long tails, and levels of the two OSCs fussed with until you feel like doing the happy dance. Run through a delay at around a third of a second or so, 330ms, some feedback, and see if it's close.
