This work explores the relationships between modularity, creative practices, analysis, and writing in interactive music, using the piece Entre Máscaras (2023) as a case study. The term 'modularity', as understood in this work, unfolds in two aspects: (1) the interconnection of interchangeable modules such as code blocks, software, instruments, and controllers that interact with each other by exchanging dynamic information; and (2) the way in which such information modifies signals and data that these modules generate or process (streams of audio, video, control data, etc.). We understand that there is a paradigm in interactive music that involves a modular logic of creative thought. In the first part of this article, we discuss the modular concepts proposed from the perspective of transduction and mediation developed by Simondon. After the initial discussions, we describe the case study's technical and creative aspects to illustrate the proposed conceptual arguments.

Αν χρειάζεται να δώσουμε τον ορισμό της ειδικής βιβλιοθήκης, ένας τρόπος θα ήταν να πούμε ότι είναι η βιβλιοθήκη που δεν είναι εθνική, δημόσια, ακαδημαϊκή ή σχολική. Έτσι τη διακρίνει και η Unesco το 1958, ορίζοντάς την ταυτόχρονα ως τη βιβλιοθήκη που είναι σχεδιασμένη για να εξυπηρετεί περιορισμένο αριθμό ειδικών, επιστημόνων, ερευνητών κ.ά., που περιέχει στη συλλογή της υλικό από συγκεκριμένα θεματικά πεδία και ανήκει συνήθως σε φορείς όπως υπουργεία, επιστημονικές εταιρείες, επαγγελματικές ενώσεις, επιμελητήρια, μουσεία, βιομηχανίες κ.λπ. (Unesco 1958). Ένας άλλος ορισμός είναι: «η βιβλιοθήκη στους χώρους δουλειάς: υπηρεσίες σε εμπορικούς, κυβερνητικούς και άλλους φορείς, που παρέχουν πληροφόρηση προκειμένου να εξυπηρετήσουν τους σκοπούς των οργανισμών τους» (Spiller 1998). Είναι ενδιαφέρον ότι στην Αγγλία χρησιμοποιείται ο όρος workplace libraries (βιβλιοθήκες στους χώρους δουλειάς) και μάλιστα έχει γίνει έρευνα για τη μελέτη αυτής της κατηγορίας βιβλιοθηκών (Spiller 1992). Μία ενδιαφέρουσα αναδρομή στην ιστορική εξέλιξη των ειδικών βιβλιοθηκών, που άνθισαν τον 20 ο αιώνα, αλλά σπέρματα είχαν ήδη εμφανιστεί και στους προηγούμενους, γίνεται σε αφιέρωμα του περιοδικού Library Trends του 1976, όπου ορίζοντας αρχικά τον όρο «ειδική βιβλιοθήκη», τον αποδίδει τόσο στην εξειδικευμένη βιβλιοθήκη (specialized library), όσο και στην εξειδικευμένη συλλογή (specialized collection) (Christianson 1976). Ένα χαρακτηριστικό γνώρισμα για τις ειδικές βιβλιοθήκες είναι ότι δεν αποτελούν μία ενιαία κατηγορία βιβλιοθηκών με κοινά χαρακτηριστικά, όπως είναι π.χ. οι σχολικές ή οι ακαδημαϊκές βιβλιοθήκες, δεδομένου ότι ανήκουν σε φορείς διαφορετικής κατηγορίας ως προς το θεματικό αντικείμενο, το νομικό πλαίσιο, το μέγεθος και την αποστολή. Οι ειδικές βιβλιοθήκες μπορεί να είναι τεχνικές, νομικές, ιατρικές κ.λπ., να ανήκουν σε συλλογικό φορέα ή σε επιχείρηση, να εξυπηρετούν συμφέροντα συλλογικά ή ιδιωτικά. Αυτή η ετερογένεια έχει ως αποτέλεσμα να μην είναι δυνατή ή έστω το ίδιο εύκολη η καθιέρωση προτύπων και κανόνων για την αντιμετώπιση ζητημάτων που έχουν σχέση με την οργάνωση και διαχείριση του υλικού τους, αλλά και με την εργασία και διοίκηση των ανθρώπων που απασχολούνται σε αυτές. Υπάρχει πλούσια βιβλιογραφία στο θέμα αυτό και μάλιστα έχει ενδιαφέρον να δει κανείς διαχρονικά

Can interactive technologies be useful for music education? This question was empirically investigated during a nine-month longitudinal study in which twelve children (1st and 2nd grade) learnt to play the clarinet. Six children (the intervention group) received instruction with the Music Paint Machine, an interactive music system that allows a musician to make a digital "painting" by playing music while making various movements on a coloured pressure mat. The other six children (control group) received the instruction without the use of technology. The overall goal of the longitudinal study was (1) to integrate the Music Paint Machine in instrumental music instruction in order to develop good practices and (2) to investigate the effectiveness of instruction with the system on the learning process. To measure the effectiveness of instruction with the system, children were administered the Primary and Intermediate Measures of Music Audiation (Gordon, 1986) as pre-and post-test. In addition, pre-tests were organised to map possible confounding variables, such as personality, home musical environment, motor skills and self-regulation skills. Although no statistically significant differences were found between the control and intervention group the study revealed important aspects about the transformative impact of technology in education. Furthermore, dealing with the complexity of a real-life educational setting and with the requirements of the quasiexperimental design, this study has provided insights on methodology (design, measures, analysis) in music educational technology research that can contribute to the further development of this branch of educational research.

In this paper we address the problem of designing an algorithm that, when given a representation of a passage of music as input, discovers all and only instances of perceptually significant repetition in the passage. The algorithm must be able to discover perceptually significant instances of repetition where the occurrences of the pattern are identical (exact repetition) and instances where the occurrences differ but are nonetheless perceived to be 'versions' of the same thing (modified repetition). Such an algorithm would ...

Technology has been widely used for educational processes; in the arts several researchers have investigated the employment of computational systems and gadgets to approach younger audiences. This paper describes the design and implementation of an interactive music system used as a tool for an electroacoustic music course for children in a rural community. The system comprises a MaxMSP digital interface and an OSC Controller app for Android. Graphic User Interfaces were created in MaxMSP in order to process individual musical parameters, this can be controlled by mobile devices using Open Sound Control OSC protocols. The interactive system was used by children (6-15 years old) to explore sound worlds during a series of electroacoustic music courses and workshops

Algumas tendencias na musica post-tonal sao consideradas muito "cerebrais" ou "cripticas" e ha- bitualmente acabam por ser incompreendidas ou rejeitadas pelo publico geral e alguns musicos profissionais. Como um esforco para superar a resistencia a estas linguagens musicais, criei uma aplicacao interativa no MAX que permite improvisar utilizando a teoria de conjuntos de Allen Forte. Entao, em de vez de serem forcados a fazer muitos calculos aritmeticos de cor antes de poder tocar uma idea musical atonal, os musicos podem instantaneamente ouvir as qualidades sonoras de um pitch class set com so tocar um acorde simples no teclado MIDI para gerar vari- acoes instantaneas de um gesto musical tocado anteriormente. Um processo de design interativo foi feito e os resultados, conclusoes e reflexoes durante as diferentes etapas do trabalho mostraram a relevância da teoria musical utilizada e a sua relacao com tecnicas de satisfacao de constrangi- mentos nos processos de c...

The role of an Interactive Music System (IMS) is to accompany musicians during live performances, acting like a real musician. It must react in realtime to audio signals from musicians, according to a timed high-level requirement called mixed score, written in a domain specific language. Such goals imply strong requirements of temporal reliability and robustness to unforeseen errors in input, yet not much addressed by the computer music community. We present the application of Model-Based Testing techniques and tools to a state-of-the-art IMS, including in particular: offline and on-thefly approaches for the generation of relevant input data for testing (including timing values), with coverage criteria, the computation of the corresponding expected output, according to the semantics of a given mixed score, the black-box execution of the test data on the System Under Test and the production of a verdict. Our method is based on formal models in a dedicated intermediate representation, compiled directly from mixed scores (high-level requirements), and either passed, to the model-checker Uppaal (after conversion to Timed Automata) in the offline approach, or executed by a virtual machine in the online approach. Our fully automatic framework has been applied to real mixed scores used in concerts and the results obtained have permitted to identify bugs in the target IMS.

This paper proposes a new model for music education based on the use of the application Soundcool, a modular system for music education with smartphones, tablets and Kinect developed by Universitat Politècnica de València (UPV) through UPV (2013, Spain) and Generalitat Valenciana (2015-2016, Spain) projects. Soundcool has been programmed in Max, a modular graphical programming environment for music and interactive multimedia creation, and uses Open Sound Control, designed to share information in real time over a network with several media devices. Our application is a creative development environment in its own right, but for running Max patches it requires only the free application Max Runtime/Max player. The pedagogical architecture of Soundcool is based on three music education scenarios that allow interaction between the various agents involved in the classroom. Soundcool is going to be used as a music education tool in several European countries through an Erasmus+ European pro...

The Pd Spectral Toolkit, a set of Pure Data objects for spectral signal processing in OS X, is described and illustrated with example patches. These objects facilitate spectral signal processing by providing commonly used data manipulations, conversions, and utilities that users must implement from scratch when working with spectral data. Additional objects are provided to achieve novel methods of spectral data manipulation, allowing more advanced spectral algorithms to be expressed while requiring fewer objects within a Pure Data patch. A comprehensive list of objects is included, and a web address to download the toolkit, its source code, and an IDE project containing the objects is provided.

Cette etude se place dans le cadre general du controle actif applique aux instruments de musique. Elle permet la modification des parametres acoustiques d’une structure simple de type clarinette (resonateur cylindrique + excitateur de type anche simple). L’objectif de l’etude est d’examiner les liens entre les modifications induites par le controle actif et les modifications perceptives qui en decoulent pour un instrumentiste. Pour cela nous developpons une methodologie experimentale basee, d’une part, sur le developpement de filtres numeriques permettant de modifier l’amplitude et la frequence des differentes resonances du tube, et d’autre part sur un protocole original de test perceptif, en situation de jeu, permettant de quantifier des jugements de dissemblance et de produire un ensemble de champs lexicaux issus d’une verbalisation libre. Les premiers resultats permettent de degager des attributs communs aux musiciens, et notamment trois criteres sur lesquels se basent les differ...

FTM is an environment that allows the processing of complex data structures such as sequences, matrices, dictionaries, break point functions, tuples and whatever might seem helpful for the processing of music, sound and motion capture data within graphical computer music systems. While FTM itself is published under a free license (LGPL), until recently the only supported host system has been Max/MSP, a commercial dataow environment for Mac OS-X and W32. In this paper we present a port of FTM to Puredata, Max's free sibling that is available for Mac OS-X, W32, FreeBSD and (among others) of course linux.

Les mesures d'admittance d'entrée des violons de bonne qualité présentent souvent un "Bridge Hill" entre 2 et 3kHz. La technique du contrôle actif permet de faire varier les paramètres de ce large pic en agissant sur les caractéristiques de la 1è re résonance du chevalet. Un régulateur, inséré dans une boucle de rétroaction, prend comme entrée la vitesse de la partie supérieure du chevalet et lui applique un couple correctif au moyen d'actionneurs. Le choix de ses coefficients permet de changer la masse et la raideur modales de la résonance choisie. Ces modifications doivent alors avoir un impact sur le Bridge Hill et donc sur le timbre du violon.

Ce travail porte sur l'étude de la qualité des anches de saxophone. Sachant qu'une certaine proportion des anches est considérée comme insatisfaisante par les musiciens, il s'avère intéressant, pour le musicien et pour le facteur d'anches, de disposer de moyens permettant de prévoir la qualité des anches. L'objectif à long terme de cette étude vise ainsi à comprendre quels paramètres physiques déterminent la qualité perçue par les instrumentistes. Le papier proposé s'attache à évaluer la pertinence de différents modèles physiques décrivant le comportement de l'anche en situation de jeu réelle (in vivo). D'une part, certaines grandeurs physiques (pression, déplacement de l'anche) caractérisant le jeu du musicien sont mesurées à l'aide d'un bec instrumenté. D'autre part, les grandeurs mesurées sont utilisées pour estimer les paramètres propres à des modèles physiques de complexité croissante. Plusieurs modèles linéaires et non-linéaires ...

Depuis Helmholtz, le fonctionnement des instruments entretenus est représenté par un système bouclé faisant apparaître un bloc excitateur et un bloc résonateur. Dans le cas de la clarinette étudiée ici, l'excitateur désigne l'anche modulant le débit d'air entrant et le résonateur le corps de l'instrument. Si cette représentation est communément admise, se pose la question de la séparabilité de ces deux blocs et de l'observabilité des grandeurs physiques qui les lient. Dans le cadre de l'étude du seuil d'oscillation, nous inspectons la validité de cette représentation indépendamment de toute modélisation des blocs : les seuils mesurés sont comparés avec ceux obtenus par la théorie des oscillateurs dans laquelle sont introduites les valeurs expérimentales des paramètres du modèle. Les pressions de seuil et les fréquences émergentes obtenues en (3) et (4) sont comparées. L'interprétation des différences fait intervenir les difficultés d'accéder exact...

De plus en plus souvent, les espaces d'écoute sont amenés à accueillir des spectacles autres que ceux pour lesquels ils ont été conçus et dimensionnés. C'est le cas d'un auditorium classique devenant le temps d'un festival une salle de concert pour musique ampliée, ou d'une cathédrale se prêtant occasionnellement à des concerts de musique chorale. En pareille situation, l'acousticien n'a d'autres alternatives que d'utiliser des abat-sons ou une assistance électroacoustique pour améliorer le confort d'écoute. En créant des réexions précoces naturelles ou articielles, ces dispositifs permettent de renforcer le son direct et ainsi de satisfaire auditoire et musiciens. Toutefois, si les outils actuels savent très bien estimer les dispersions temporelles de ces réexions, il n'existe pas de méthode globale pour veiller à leur répartition homogène dans la salle. Ce contexte particulier a motivé le développement d'un outil de qualication spatio-temporelle des réexions précoces dans une salle. L'idée générale de l'approche proposée est de combiner l'information temporelle issue de la mesure d'échogrammes spatialement distribués avec un module de localisation angulaire par goniométrie. Ce dernier est basé sur l'analyse des diérences de temps de propagation qui existent au sein d'un arrangement de capteurs de géométrie connue en présence d'une source située en champ lointain. Par extension, on dénit la chrono-goniométrie acoustique comme une méthode de localisation active basée sur l'estimation conjointe des directions et des instants d'arrivée. Après avoir introduit le contexte de l'étude, nous formulerons le problème de localisation dans une salle tout en précisant les hypothèses de travail. Puis, un aperçu réaliste des performances in situ du chrono-goniomètre pour localiser simultanément plusieurs réexions sera présenté.

La création musicale contemporaine réclamant sans cesse de nouvelles sonorités, le musicien-compositeur a été amené dans la seconde moitié du XXème siècle à imaginer ou construire lui-même l'instrument qui incarnera son projet esthétique : quelques rares inventions ont pu ainsi passer à la postérité. Plutôt que de développer de nouveaux instruments, utiliser l'électronique pour élargir la palette de sons des instruments traditionnels s'est rapidement imposé comme une voie alternative et prometteuse. Elle permettait notamment de capitaliser sur le patrimoine gestuel des interprètes d'instruments traditionnels, aussi bien pour insuffler leur expressivité dans la musique que pour faciliter la diffusion des oeuvres. La première partie de ce mémoire est consacrée à une typologie des pratiques d'hybridation des instruments traditionnels par l'électronique, qui, de l'instrument virtuel à toutes les pratiques possibles de musique «mixte», constituent en réalité un continuum de réalités musicales aux frontières assez poreuses. La seconde partie est une présentation de l'instrument, un tam chinois, dont on se propose de réfléchir à l'hybridation : on prendra dans un premier temps le point de vue de l'acousticien avant de réfléchir dans la troisième partie, en tant que compositeur, sur l'opportunité et les finalités d'une telle hybridation. Une fois le cahier des charges fonctionnel de l'hybridation établi, commence la partie expérimentale de la recherche.
La quatrième et la cinquième partie explorent deux approches différentes d'hybridation (au sens de la typologie développée en première partie). Deux dispositifs matériels et logiciels sont définis et testés en studio; les résultats de ces tests sont comparés au cahier des charges. Seule la première approche aboutira à une création artistique sous la forme d'une pièce (Re/flexions I). La dernière partie pose la problématique et les enjeux d'une continuation de ce travail sous deux formes alternatives : un véritable instrument hybride où les traitements électroniques seraient commandés par la gestuelle du percussionniste, ou bien au contraire: une installation sonore interactive dont la conception serait guidée par une approche éco-systémique. Ils pourront donner lieu à une nouvelle itération du processus d'expérimentation.

Some tendencies in post-tonal music are regarded as very “cerebral” or “cryptic”, and are often
misunderstood, when not rejected, by the uninitiated public and even by some professional
musicians. As an effort to overcome my resistance to this languages, I designed an interactive
application in MAX that allow to improvise using Allen Forte’s set theory. So, rather than being
forced to do a bunch of arithmetic calculations by heart before play a single note, musicians can
hear instantly the aural qualities of determined pitch class sets by playing a simple chord in a MIDI
keyboard to generate variations of a previously played musical gesture. An iterative design process
was carried on, and the results, conclusions and reflections during the different stages of the
work showed the relevance of the music theory applied and its relation to constraint satisfaction
techniques in music composing processes.

The field of interactive music systems (IMSs), beginning in the 1980s, is still relatively young and fast moving. The field of music theory-analysis, during the same period (since 1980), has undergone a major transformation in terms of technological innovations, flexibility, and breadth. The two fields have not really caught up with each other. It will be interesting to see what arises as they do — especially as both fields have become more concerned with the role of the body and embodied cognition. Framed in terms of contrasting epistemological orientations, this essay considers some relevant developments in IMSs, music cognition, and music theory and analysis, leading up to the present. The most popular approaches to music cognition and to IMS design are rationalist (Ashby 2010), exploiting the ‘correct’ embodiments of music (Godøy 2004, Leman 2007, Paine 2009) based on affordances (Gibson 1977, Kelso 1998). This essay, however, advocates a pragmatist (Ashby 2010) approach inspired by music analysis and exploiting the potential of kinesthetic learning (associative learning). Prompted by a progressive approach to music analysis, theory, perception, and cognition (Dubiel 1999, Mailman 2007), interactive music technology can also be constructive, flexible, and progressive, by exploiting kinesthetic learning from immersion in new and unusual motion-to-sound mappings derived from dynamic formal processes in analysed music. In this way, immersive interactive systems offer an opportunity systematically to learn new associations based on principles theorised in response to analysis. Experience of these systems essentially ‘rewires the brain’, thereby exemplifying what Korsyn (2004) has attributed to Lewin’s (1986, 1987) approach to music perception: the ironist approach, as formulated by Rorty (1989). Thus a pragmatist ironist experimental (PIE) approach is articulated. Rather than committing to any particular ways music is already embodied, this approach acknowledges the flexible nature of embodied musical experience. It forges and uses interactive music technologies continually to redescribe and therefore reform how music is embodied, thereby disembodying to re-embody music, expanding how music is heard, contemplated and experienced.

This paper speculates on the potential of a limited set of interacting particles to produce interesting temporal structures in a two dimensional world. Particles exchange information locally though global complex behavior emerges spontaneously. The imaginary physics of the world is described in an ensemble of 2D arrays. An autonomous genetic algorithm continuously aims to optimize the arrays in an effort to maximize diversity. In addition, an external user may interfere in a subtle way; external gestures are integrated into the arrays in proportion to their strength. A quite elaborate mapping scheme creates relationships between complex system behavior and parametric MIDI events.

This paper describes research into granular sampling, including "time-stretching" techniques, and presents a musical application using the IRCAM Signal Processing Workstation in which granular sampling is controlled via turbulence algorithms and stochastic processes in a real- time compositional environment. Additionally, an important aspect of this work involves the control of granular techniques via the real-time detection and tracking of musical parameters of live instruments.

This paper presents real-time musical applications using the IRCAM Signal Processing Workstation which make use of FFT/IFFT-based resynthesis for timbral transformation in a compositional context. An intuitive and straightforward user interface, intended for use by musicians, has been developed by the authors in the Max programming environment. Techniques for filtering, cross-synthesis, noise reduction, and dynamic spectral shaping are presented along with control structures that allow for both fine timbral modification and control of complex sound transformations using few parameters.

Jourdan 2008] on the study and the use of audio descriptors for real-time performance of electroacoustic mix music, and as tools for computer-assisted musical analysis. Our main goal, in this paper, is to propose easy and efficient strategies for event detection in the context of real-time mix music (acoustic and electroacoustic music). We will examine three cases of the use of audio descriptors to build event detection functions: spectral slope, spectral standard variation and the construction of compound descriptors.

In this paper we address the problem of designing an algorithm that, when given a representation of a passage of music as input, discovers all and only instances of perceptually significant repetition in the passage. The algorithm must be able to discover perceptually significant instances of repetition where the occurrences of the pattern are identical (exact repetition) and instances where the occurrences differ but are nonetheless perceived to be 'versions' of the same thing (modified repetition).
