Aléas : original virtual music software/instrument

Aléas arose from a reflection about how to materialise/draw sound with 3D images. It is a synthesis software, treating sounds and abstract images, able to create a dialogue with reality by using tactile sensors. It thus creates an interactive, sensitive relationship with the audience.

It allows creating, modifying, observing and manipulating moving 3D shapes. By manipulating the sensors, the spectator or the artists can continuously intervene on the whole structure by playing with the different variables: order, side-by-side positioning, overlapping, speed, rhythm, harmonic pitch…

Each user appropriates the system as he create particular processes of repetitive poliphony where parts overlap then disappear into hypnotic swirls.

The audience determines the future of the work by experimenting with infinite orchestrations. They easily control the tune thus generated: a direct relation between man, image and music.

1. SpherAleas : Interaction of space

SphèrAléas is made of a half-spherical structure and of an evolutionary device wich makes man, image ans sound interact thanks to digital tools. The machine becomes the creator’s ally to produce pictural and sonorous shapes. This space is ideal for collective performances; it accomodates in its center a constellation of visible shapes, spinning sound loops and luminous vibratory elements.
The dome-bubble hosts universes and objects endowed with life. They are articulated like subtle microcosms in conversation.

The visitor, actively engaged in this matrix space, creates sonorous and pictural interstices awakening his senses and opening unexpected territories to his imagination. Each participant gives himself up to this sensitive complicity cradled by flows of random emotions, justifying its necessity by the sole intensity of the present meeting.

The scenography is designed for complete immersion of the spectator thanks to interactive sensors, a multipoint sound diffusion, a video projection system (180°), within a half spherical membranous architecture.

This original shared experiment becomes a poem of sensations: inside this space, sensitive perceptions are amplified, modified until a multitude of unexpected metaphorical worlds resonate. SpherAleas is a safe space of oneiric creation in which the public creates, handles, juxtaposes, superimposes sonorous, pictural shapes unstable and reactive.

Within this half-sphere, the spectator manipulates and influences the artwork. He is invited to create, to try out or feel pictural and sonorous structures reminiscent of the living world. Through his performance, the spectator develops a work made of hypnotic universes. He becomes creator and explorer of a microcosm born of sound and image samples.

The show is ever changing…

2. Interactive and immersive device

Designed for real-time musical and visual interactions, the immersive space is a semi-transparent half-sphere, 2.50 metters-high (8.2 feet-high). This structure is used as a screen for wide-angle projection similar to that of planetariums. Then the audience can be totally immersed in unreal and captivating atmospheres.
Speakers and amplifiers allow games of spatialisation of sound. Inside the dome, the audience, seating or lying, can manipulate tasctile sensors or simply daydream. These manipulations are interpreted by the Aléas software which produces the sound and the 3D compositions. By mixing these image and sound structures, like an orchestra, spectators create symphonies to contemplate.

3. Ephemeral firmament - Performance / Concert

Gregory Lasserre & Anais met den Ancxt from Scenocosme play in live with a specific interface for visual and sound : Aleas.

This performance was born following during experimentations inside the immersive installation SpherAleas : www.spheraleas.com. A specific scenography and device was created for Aleas : original virtual music software/instrument.

During about thirty minutes, the spectator is guided in a succession of visual and sound micros-universe.

Aleas interface reveals visual and sound performances to spectators. They see and hear on live various handling of the duet. Indeed, during interventions, the sound takes shape in the circular space of projection. Here the musical intervention is alsos an invitation with contemplation. Myriads of visual and sound shape are accumulating in hypnotic sound superpositions

Each performance offers a new dialogue or visible duel. In the opposite of the standard veejaying and deejaying performances, the spectator follows exactly the musical and visual evolution as well as the performers. Here, all is revealed and linked. The duel reveals moments in complicities, doubts, errors, chaos... but which constitute the source of creation of these micros-universe. The Random concept developped by John Cage is also has source of inspiration for their artwork. Each performance offers a multitude of possible made by minimalists elements.

The musical dialogue gives life to sound creations in suspension.

In connivance with repetitive music, the duo plays with unstables and reactives sounds. Inspired by La Monte Young, Scenocosme tries to immerse spectators in an experiment of body in a sound space favourable for daydream.
