This is certainly an interesting thread. I'm wondering, though, about the
mathematics of wind in trees, stock market fluctuations, body movements,
etc., and whether in the end the sort of CV patterns that could be derived
from these sources would be distinguishable from the 1/f patterns
obtainable from the Infinite Melody module. I am not sufficiently versed
in math to know. I do suppose that such odd sources of CV might be useful
for conceptual art forms. But isn't the resulting structure of the music
produced going to depend as much -- or more -- on how you patch up the
controls, as whether the origin is an electrical random source (which is
natural, too) or some other physical phenomenon?
I have had thoughts along these lines before, and looked into bio-feedback
equipment as a possible means of controlling my synthesizer. At least with
bio-feedback I would be in the loop.
