The same can be said about any technology that has not been
extensively studied. I think that there will be more to this than you
would see at first glance.

One question I have been wondering about: if you take a walsh
decomposition of a periodic waveform, and then start delaying the
partials, what happens?

What if you start scaling the coefficients ak \in [-1, 1] such that
for example ak' = ak^(1+r) for r \in [0, 3]? or otherwise, such that
ak'' = 1-(1-ak)^(1+r) ? Is there a way to scale the coefficients so
that the timbre stays relatively the same while the overall loudness
increases and perhaps the weighting of the waveform 'rises' (so, in
the direction from the pink noise spectrum to the white noise
spectrum)?
