Re: Octophonic sound system

Cool stuff, Richard!  Inspiring to hear about it!

A pan control seems to be a problem in general for immersive sound set-ups.
I suppose there's probably a better word than "panning" since we mean
placement in 3-space.  Maybe a joystick with a pot on the stick's top.
Moving the stick from side to side and forward to back places the sound in
2-space; twisting the stick (or rather the pot on top of the stick) adjusts
the "altitude" of the sound.

For a live performance, I've thought about a more visually appealing 
interface -- The performer stands (or sits) in a space analogous to the
house.  He or she picks-up a token of some sort (we'll call it a
"control-egg" for our discussion).  The egg has one or two buttons on it 
a link (probably wireless) to a control processor.  The performer also
selects a particular channel of sound to control.  When one button on the
egg is pressed, the 3-space location of the selected sound follows the
location of the egg.  For example, as the performer moves the egg in a
circle, the sound pans around the room.  Releasing the button "freezes" the
sound at that location.  This controller is similar to a Buchla Lightning,
but with an added dimension of control.

Great fun could be had (I suspect) by building an "industrial strength"
control egg and tossing it to the audience.
