Okay I'm all new when it comes to synthesizing so please forgive me for posting such a stupid question 
I've learnt that sine waves contain no overtones at all. I wanted to try this out by playing a sine wave in one of vanguards oscillators and check the frequency response in a frequency inspector that I inserted to the main output channel. This is what I got when I played the C3 note: http://www.geocities.com/rakmannen/overtones.jpg ... The result wasn't a narrow response, there's sound all from the start up to about 400hz. And then there's some sound right above 10KHz too, extremely weak but still, it's there.
So how about the sine wave not producing any overtones? What have I been missing out here?

yes, a clean sinewave sounds too bland (u know how it sounds, if a channel on the tv isn't working, they have the test image, and on the background they play a constant perfect sine-wave, very irritating, but it's the best example i could find), and because those perfect sines sound so boring they never put a perfect sine as an osc in a synth... |

hahaha so the answer was as simple as that??? Well, I guess I should have payed more attention to the tip I read in a tutorial - saying that every synth has its own characteristics and the features should never be assumed to be the same between synth A and synth B.
Thanks for your quick and intelligent reply, Fregle
