Can someone translate that into Operator language?
Operator's filter doesn't self-oscillate (as far as I know). You can get sort of similar effects by using a relatively pure tone and automating the fine tuning, or the transpose. To see what this could sound like load up something like fabfilter timeless and turn the resonance all the way up (twin won't do it, and volcano is tricky to actually get to self-oscillate -- there are probably lots of other devices that do this, but this is the one I have).
For melodic swooshes I've actually had the best luck using a MSEG in Zebra 2, personally. You have a lot of control and you aren't restricted to whatever tone your filter characteristics tend to produce.
how do I get that Vibrato sound Out of the sweep. It doesnt sound clean
Whoa, I'd never noticed it before, but operator's noise sounds bad. It is obviously looped and has some very non-random characteristics. At F3 it sounds like some kind of machine!? and at some frequencies the non-random characteristics are the dominant sound. Edit: apparently this is in purpose, the manual suggests that if you want statistical randomness you modulate it with another oscillator, or use the LFO in S+H mode on it. Anyways, I think the loop characteristics of the noise is what you are hearing.
