Multiplexing /Πολυπλεξία/ is a Kinetic Sound Installation created in 2019. It is made of plywood, Arduino micro-controller, lip-gloss boxes, DC motors and magnets.

In telecommunications and computer networks, multiplexing (MUX) is a method by which multiple analog or digital signals are combined into one signal over a shared medium. The aim is to share a scarce resource. For example, in telecommunications, several telephone calls may be carried using one wire. Multiplexing originated in telegraphy in the 1870s, and is now widely applied in communications. In this particular work, the idea of MUX is transferred into the sound domain. A series of logically performed processes are channeled and distributed through a transistor array, activating a matrix of micro-sound sources and building a larger, mechanically generated, soundcloud.

The piece was premiered at MOMus-Experimental Center for the Arts at the port of Thessaloniki on May 2019. (www.cact.gr) as a part of the exhibition Visual Symphonies 

Since 22 June 2020 Multiplexing belongs to the permanent collection of MOMus Museum of Modern Art in Thessaloniki

DeFence was a large scale happening that took place at Megaron Concert Hall of Thessaloniki on 21 of June 2019 on the occasion of the celebration of the world day of music. As a part of the performance the fence of the east bound side of the Concert hall was demolished by a massive amount of approximately 100 performers motly students of the School of Fina Arts of Aristotle Univeristy of Thessaloniki and the National Theater of Thessaloniki

The performance took place around 23:00 in the evening in very low light conditions. Conducted by 4 conductors who were receiving audio information/instructions from the composer wirelessly, in real-time, and accompanied by electronic sounds, the performers used hardware tools to make sounds on the metallic mesh eventually brining it down by cutting it in parts and then moving themselves away. In a deliberate action of breaking any means of human isolation, discrimination and oppresion the piece, despite of its brutal content delivered a message of unification.

Graffiti is an interactive sound installation. The concept of the piece derives from the technique of graffiti found in visual arts, where anyone, not necessary skilled, person can try to express publicly in the visual domain without always being identified. In Graffiti, the visitors are invited to use their smart devices to trigger sound events in real-time acting as composers, conductors and performers at the same time. A special system, consisting of a Raspberry Pi running SuperCollider is built to emulate an imaginary symphony orchestra. The system responds to input commands and generates sounds in real time New soundscapes can arise on the fly in a playful way – giving the opportunity for each participant to feel the excitement of music creation even without any pre-developed musical skill. Many people can play at the same time being at the place of the installation but also remotely. This was a new approach in making music ensembles of amateur musicians is examined.

Les illuminations is a stochastic sound installation created in 2003. The installation was first exhibited at the Music Department of Aristotle University of Thessaloniki as a part of Music Circus Project directed by Danae Stefanou. It consists of a Max/MSP application that generates filtered white noise sounds, while at the same time projecting geometric shapes and displaying the poem “Départ” by Artur Rimbaud.

Départ
Assez vu. La vision s’est rencontrée à tous les airs. Assez eu. Rumeurs des villes, le soir, et au soleil, et toujours. Assez connu. Les arrêts de la vie. – O Rumeurs et Visions ! Départ dans l’affection et le bruit neufs!
Arthur Rimbaud, Illuminations

Enough seen. The vision has been encountered in all skies. Enough had. Sounds of cities, in the evening, and in sunlight, and always. Enough known. The stations of life. — O Sounds and Visions! Departure amid new noise and affection!
