This patch requires the abstraction for hexagonal radial panning to be saved in the Max file search path with the name "hexagonalradialpanner~". It demonstrates the 6-channel panner, and shows how the sound can be moved around the space in a repeating circle by using a phasor~ to supply the panning angle.
For speakers that are configured in a circle or in the vertices of a regular polygon, you can give a sense of localization of a sound by calculating the radial angle of the sound's desired virtual location relative to the center of the listening space, and then panning the sound between the speakers that are closest to that virtual location. In other words, for any virtual location that you want to imply, you need to calculate which speakers are closest to that location, and then pan the sound between those speakers.
