ReCoDIN stands for “representation and control in the interactive design of digital musical instruments”, the topic of a doctoral research project started in 2016.

Abstract : Digital musical instruments appear as complex objects, being positioned in a continuum with the history of lutherie as well as marked with a strong disruption provoked by the digital technology and its consequences in terms of sonic possibilities, relations between gesture and sound, listening situations, reconfigurability of instruments and so on. This doctoral work tries to describe the characteristics originating from the integration of digital technology into musical instruments, drawing notably on a musicological reflection, on softwares and hardwares development, on musical practice, as well as a number of interactions with other musicians, instruments makers, composers and researchers.

This PhD was led under the joint supervision of Jean-Dominique Polack from the Lutherie-Acoustics-Music team at Institut ∂’Alembert (LAM, CNRS-UMR7190) and Pierre Couprie from the Research Institute in Musicology (IReMus, CNRS-UMR 8223).

Advisor : Hugues Genevois from the Lutherie-Acoustics-Music team at Institut ∂’Alembert (CNRS-UMR7190).

This research was supported by Collegium Musicæ at Sorbonne Université.


This research led to the development of various Open-Source tools and softwares, some of which are described in academic publications  (see below). Feel free to fork them on GitHub !

  • LAM-lib : a random collection of objets and utilities for digital luthery in Max.
  • ModularPolyphony (MP) : a protocol and set of abstractions in Max, allowing expressive control of polyphonic processes, connected in a modular way.
  • ModularPolyphony-TUI (MP-TUI) : a set of objects and utilities built on top of MP, meant for designing custom multitouch tangible user interfaces (TUI).
  • Sagrada : a library for audio-rate control of modular processes, particulary targeted at granular synthesis.
  • John, the Semi-Conductor : a web-based collective score generator, editor and player, crafted for helping collective free improvisation of electroacoustic music.

Sagrada: Sample Accurate Granular Synthesis


Sagrada is an open-source Max package performing sample-accurate granular synthesis in a modular way. Grains can be triggered both synchronously and asynchronously. Each grain can have its own effects and eveloppes (for instance the first “attack” and last “release” grains of a grains stream).

You can get it from the Github repository:

Sagrada screenshot will play grain synchronously or asynchronously (click for video demo)

Sagrada multilayers
sagrada.multilayer~ allows for running multiple streams of grains in parallel (click for video demo)

Sagrada was partly developed during my PhD at LAM. It was inspired by the very good GMU tools developped at GMEM (and its sample-rate triggering) and the FTM package developed at IRCAM (and its modularity). Not to mention all of Curtis Roads’ work on granular synthesis.

Table Sonotactile Interactive

The Interactive Sonotactile Table is a device invented for the Maison des Aveugles (“House of the Blinds”) in Lyon by french composer Pascale Criton in collaboration with Hugues Genevois from the Luthery-Acoustics-Music team of the Jean Le Rond d’Alembert Institute and Gérard Uzan, researcher in accessibility.

I coded the embedded Arduino boards as well as the Max patch for the gesture/sound interactive design. The Table Sonotactile Interactive is part of a larger project : La Carte Sonore by Anne Maregiano at the Villa Saint Raphaël :


Live audio+visual performance by FORAGES.

Sounds and images are operating in real time on stage. FIB_R plunges us into a body, that of the optical fiber itself. The eye opens onto its invisible omnipresence, penetrates the network fabric and sounds out the running processes.

FORAGES is Gladys Brégeon and Vincent Goudard.

PANAM (Pédagogie artistique numérique accessible et multimodale) is a research and development project led by Puce Muse and concerned with the development and analysis of HCI strategies and tools for collective music practice with digital music instruments. It focuses on the accessibility of such tools for disabled people.

As part of the LAM team, several tools have been developed for the mapping, visualisation, and building of digital music instruments. They have been implemented as modules for the Meta-Mallette software (©PuceMuse), and are available as part of the LAM-lib, a software library for Max/MSP.

The digital lutherie toolkit you need.

LAM-lib is a toolkit for Max/MSP providing all kind of useful goodies you need when building digital music instrument with Max. I started it during my work at the Lutherie Acoustique Musique lab. It is distributed under LGPL licence so that you can check it, fork it, buy it, sell it, use it, break it, fix it, trash it…etc. Just credit it.

John — the semi-conductor

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.

Le phonétogramme

Le phonétogramme 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.
