Full Spectrum Audio-Visual Synthesizer: Introducing Procyon, a new kind of light and sound experience, melding a full spectrum of color choices with clean, pure digital sound. The resulting new mediaform can be used to modulate states of consciousness in rich new ways. Its state-of-the-art color synthesis elements can modulate smoothly between fields of pure color (ganzfeld), through subtle shimmering effects, to full-on flicker frequency range up to 75 Hz. Each color channel (red, green, and blue) is independently programmable, allowing up to three simultaneous stimulation frequencies at once. This variety of innovative visual effects enables a new kind of audio-visual experience, and can closely match color to the desired mental state. Procyon also has the ability to precisely synchronize audio material on a CD or MP3 with a Procyon program. This exclusive feature, called SynchroMuse, is ideal for use with color-work, language learning, hypnotherapy, personal growth and the immense libraries of music now available.
