AIM-Framework

AIM is a Max package helping to structure patches following a “Model View Controler” design pattern. 
Declare parameters and models, in possibly nested combinations, save presets, readily available in any other model instance.
 Create custom GUIs for your components and easily monitor and control any part of your patch.

The core part of the package was presented at the Sound and Music Conference (SMC’22) organized by GRAME in Saint Etienne, France.

ReCoDIN [PhD]

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.

Tools

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.

Xypre — a sound-enhanced multitouch screen interface

Xypre is a multitouch-screen based interface enhanced with contact microphones and tactile speakers that I designed for live performance. It was built in just a few days for a forthcoming performance. I am playing it in FIB_R and with the ONE ensemble.

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:

https://github.com/vincentgoudard/Sagrada

Sagrada screenshot
sagrada.play~ 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.

raspiCamGrab for peauème by Gladys Brégeon

Development of an autonomous microscope camera device running in OpenFrameworks on a cased Raspberry Pi, for the art installation peauème by artist Gladys Brégeon.

The program is self-bootable with a hidden boot sequence so that it can be easily (and elegantly) started in the exhibition space. It allows for hue, saturation, brightness, RGB gains and contrast settings.

Code is open-source and available there : https://github.com/vincentgoudard/raspiCamGrab

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].

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. The table was designed by Pierrick Faure (Captain Ludd) in collaboration with Christophe Lebreton (GRAME)

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: https://www.mda-lacartesonore.com.

mp.TUI — a Max package for multitouch screen interaction

mp.TUI is a Max package with OpenGL UI components ready for multitouch interaction (using the TUIO protocol).

It was presented at the ICLI’2018 conference in Porto and was used in a series of projects including the Phonetogramme, Xypre and FIB_R.

FIB_R / forages

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.
Production : AIAGOS

Duration 40min
