Well, he is correct in that the basic waveforms of "classical" type is all
sharp changes except for sine. However, those sharp forms to some degree 
represents the high overtone content which is used in negative synthesis.
Things tend to round up alot when sent through the filter(s).

One thing which I would like to point out is that the actual waveshape of a
tone isn't as interesting as the overtone strength. Shift the phases around and
you got a different waveshape altogether. The actual relative phases of
overtones isn't important unless for some non-linear waveshapers. Move those
relative phase around though and we are talking... but phases didn't matter?
No, but the _changes_ do, they are phase modulations!

We are a bit booring on how we fiddle with overtones and modulate them, that's
more than true, but I don't think we really can create a new waveform magic
waveform, but new innovative modulation is where I would bet my money.
