John — the semi-conductor (reactive web version)

John (“the semi-conductor”) is an open-source software designed to help collective free improvisation. It provides generated screen-scores running on distributed, reactive web-browsers. The musicians can then concurrently edit the scores in their own browser. John is used by ONE, a ensemble playing improvised electro-acoustic music with digital musical instruments. One of the original features of John is that its design takes care of leaving the musician’s attention as free as possible.

John was presented at the TENOR’2018 conference in Montreal, CA [pdf here].

John — the semi-conductor (Max version)

John, the semi-conductor.

John is an application meant for collective free improvisation, which was born out of the needs encountered in free improvisation practice with the Orchestre National Electroacoustique.

Namely, John was invented as a virtual companion to find stimulating answers for issues encountered in collective free improvisation, like precise timings for transitions between contrasting parts, articulations of large movements, or the proposal of unusual scores taking us off the beaten path.

It is made of two parts :

  • a score editor which can generate random scores based on constraints and probablities defined by the user
  • a real-time “conductor” displaying the score during live performance

Its name refers to both John Cage and John Doe.

The original development was made with Max (quite a challenge!), then ported to a reactive web app.

Le phonétogramme — an interactive installation for voice analysis

Le phonétogramme is an interactive audio-visual booth created and developed for the “Cité des Sciences” museeum in Paris. It consists in a graph showing the pitch versus the loudness of a voice. It shows various characteristics of one’s voice, including the ambitus, the change of amplitude at vocal register shifts, and possible voice disorders.

The installation involved a multitouch screen to control the multilingual app for the Cité des Sciences audience. A distance sensor was also used to ensure the distance between the user and the microphone was correct. All the graphics and sound interaction design was made with Cycling’74 Max.

It was a challenging thing to design the UI with Max/jitter, but a good opportunity to test the limits of what could be achieved there. This project triggered the development of the MP.TUI package.

Morphogenius

Morphogenius is an application for tablet that was proposed for the exhibition on Leonardo Da Vinci at Cité des Sciences, Paris. It is inspired by Leonardo Da Vinci morphological drawings.

It allows to “transfer” reality as captured by the tablet’s camera into 3d drawings. The camera stream is processed with an edge detection algorithm easing the readability of shapes and structures. All drawings are done in 3d and the user can move, rotate and zoom them in any direction.

Wyschnegradsky

Ivan Alexandrovich Wyschnegradsky (Ива́н Алекса́ндрович Вышнегра́дский) was a Russian composer primarily known for his microtonal compositions.

Pascal Criton, a french composer of contemporary music as well as a musicologist who studied Wyschnegradsky’s works, created an interactive piece inspired by Wyschnegradsky’s “ultrachromatic compositions” for association Puce Muse.

I designed a collective instrument able to produce complex polyrhytmic sequences of filtered sound texture. Each step of the sequence can be assigned a color nuance and a pitch, possibly micro-tonal. The result produces visual and sonic moires, reminding of Wyschnegradsky’s chromatic drawings.

You can get it from the Méta-Librairie website.

Radio roulette

Development of a “radio-roulette” Max patch for the “Atelier de Création Radiophonique”. The application is receiving a set of live radio streams across Europe.  The user can then “launch” the roulette and the application is wheeling in a round-robin across the various radio streams.

RADIO DAY : AUX QUATRE COINS DE L’EUROPE © Radio France

THE 4 CORNERS OF EUROPE Live from Paris, a special program to celebrate the Radio Day of European Cultures By Philippe Langlois and Frank Smith Director Gilles Mardirossian Europe, we know, is an immature continent, where development is coming gradually. This program is not aimed to treat about political nor economical trends, but its purpose is to reinstate all the poetic power that this territory had. To achieve this, we shall connect – we shall hear them – with the four islands which are on the four corners of Europe : Sptizberg, Acores, Canaries, and Cyprus. Initially build as a showcase, this program will associate for each country a variety of several sounds streams : some good traditional music, a compilation of documentary archives, a mixture of landscape sounds as well as the live broadcast of local webradios and the satellite communication of the weather forecasting centers which are on site. The responsability of the final product will be the one of the person in charge of the program, who will have total freedom to compile the various sounds collected.
