Walters is at it again!
Since you're a pro, I am sure you have some sort of Waves bundle... Some of them come with Doppler. If you have a mono track, you'll need to route it to a Stereo Bus (Group in Cubase speak) and stick Doppler on that.
For emulating "rotation" I wouldn't use an audio track in a DAW. I'd load that sucker in a sampler and setup the following:
1. Setup two LFOs running at the same rate, but 90 degrees apart.
2. Setup the following patch: Sample->2 pole LPF (no resonance)->Amp.
3. Route LFO1 to pitch, LPF cutoff and Amp modulation. You want to modulate all these guys in the same direction... i.e. LFO goes up, so does pitch, filter cutoff and Amp volume, it goes down, they follow along. You probably don't want to have too wild a pitch modulation, probably 1/2 step (100 cents) in each direction max.
4. Route LFO2 to pan.
Play some note and smile.
If you wanna get fancy, and if your sampler will allow you to do so, route your patch to a reverb/delay and have LFO1 modulate dry/wet amount in the OPPOSITE direction from pitch, LPF cutoff and Amp modulation. Basically the signal moves "away" and becomes more verby, comes close, sounds more dry.
