Just to be precise, if you want the exact same circuit without the 0 and
the +, you can replace them with a wire, so it will be one signal feeding
back into something with one input: the wire.
process(carFreq, modFreq, multOfMod, multOfCar) = _ ~ ((((_, multOfMod:*),
modFreq:+):os.osc, multOfCar:*), carFreq:+:os.osc);
