Mixed Motions | Cavalry App
If you're needing to add more motion to your keyframes - you might need to check out the Behaviour Mixer. It allows you to combine well..... behaviours! Noise, Oscillators, Values (Keyframes) plugin what you want - sync things with music - (in hindsight I wish I'd done that!)
As always, thanks for watching - this one assumes you know a thing or two!
