What are Light/Sound Sessions?
A modern light/sound synthesizer is a microprocessor controlled device designed to create stimulation with several controlled parameters: (frequency, volume, intensity, tone, pitch, phase, duty cycle) and various other features. A typical machine will have a number of built-in sessions that provide sequences of changing stimulation, designed by the session composer using the basic repertoire of machine features. Some machines are programmable, meaning the user can create his or her own sessions, and some can download sessions from a personal computer. The quality of the built-in sessions is very important unless you plan to compose everything yourself. Creating sessions for a light/sound synthesizer is still an art form — there is no known “best protocol” for a relaxation session (or any other kind of session), and session designers will argue hotly over the best approaches. Different people have different reactions to sessions, so using one of these machines is a bit of an explorator
