Not that I want to see the thread start up again, but arnt those just
pictures of lissajous figures?  If so, arnt they just a different way of
viewing standard waveforms and not some weird "circular/spiral" waveform?

I mean, if you turn off the sweep on your scope and view a sinewave it looks
like a pulsing verticle line...  which isnt a new waveform but just a way to
view a standard waveform.

The biggest problem I had with the whole circular waveform thread was that
you see on a scope is a visual representation of a frequency, for us, of
sound, which has no bearing on the "sound" at all and in fact is fairly
arbitrary.  The closest thing in my mind to a circular waveform would be
the output of a sheppard generator, which wouldnt "look" circular at all but
sounds circular.

Also, reality check... do we care what a waveform "looks" like?  I mean, the
point of a synth is the sound right?

Oh god, what have I done.
