Full Spectrum Audio-Visual Synthesizer

Introducing the Procyon from MindPlace, a new kind of light and sound experience, melding a full spectrum of color choices with clean, pure digital sound. The resulting new media form can be used to modulate states of consciousness in rich new ways.

mind machine procyon light and soundImagine a world of pure, jewel-like color illuminating both visual and mental fields. From a single hue indefinitely sustained to a slow morph, brighter then dimmer, fading from deep blue to aqua, then transitioning through a rainbow of precisely sequenced hues and shades.

Such colors can profoundly affect consciousness and mood. Blues and greens instill a meditative spirit of tranquility, golden light elicits focused awareness, and crimson, total alertness.

Flickering light can also affect and alter mental state in often dramatic ways, eliciting the "entrainment effect", dwelling at the threshold of sleep, or activating visual creativity. If you are new to this technology, you can learn more about it here.

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.




The Procyon includes 50 unique, pre-programmed light and sound stimulation sequences (called sessions, or programs) with its internal memory, each designed with a specific goal in mind. All sessions were designed to support the mental processes required to integrate the lessons of daily life and we believe you will will help make your inner travels more productive.

It has long been known that color can have a profound effect on cognition and perception. Research has shown that pure colored light can achieve this same goal: for example, red light is more effective at inducing mental and physiological activation, while blue light reduces such activation and can instill a sense of deep calm. Yellow, on the other hand, helps the mind focus while studying and can allow access to "peak performance" mind-states. The Procyon sessions take full advantage of this use of color.

It is possible to use the Procyon to produce pure, jewel-like colors which do not flicker at all. It can also play sequences which unfold gradually, or shift rapidly from hue to hue. When this is done in the range of about 4 to 20 times per second, especially unusual visual and psychological effects can be produced, inducing the illusion of complex, shifting geometrical imagery. This imagery can be so compelling that the mind clears of extraneous thoughts and distractions and the other stresses of daily life. In this way the Procyon is a form of "accelerated meditation."


Session Types


Tranquility and calming: These sessions use mostly "calming" colors, especially blue and green, but also shades of purple and occasionally other colors for visual variety. They tend to change slowly and are intended to lead the mind towards a state of tranquility.

Before bed: Similar to the calming sessions, but even slower and again focused on mixes of blue and green light. The goal is to help clear the mind before bed. Some users have reported having unusually vivid dreams with these sessions.

Learning: Most of these are based upon the twilight learning and super-learning paradigm, and are intended to lead your mind into a light trance-like state known as hypnogogia.

Peak performance (6 Sessions): Mostly "middle of the rainbow" colors and frequencies associated with the goals of mental activation and peak performance; often used for learning and sports preparation.

Energy/Rejuvenation: More active; patterns shift rapidly and are intended to prepare the mind and body for activities such as sports and other physical activities, or before meetings and tests. Perfect for use during breaks from work and for study.

Visualization/artform/entertainment: These sessions demonstrate the more purely aesthetic aspects of the Procyon, and are intended to induce more complex (even hallucinatory) visual imagery, and as preparation for exploring altered states of awareness.
