RTP MIDI : Recovery Journal Evaluation and Alternative Proposal

An RTP payload for MIDI commands is under development. As a part of this draft, a default resiliency mechanism for the transport over lossy networks defines a journalling method called recovery journal. But the theoretical size of this recovery journal can be very large and its format is complex. This report will present an empirical evaluation of the recovery journal size based on a few MidiFiles. We will also propose an alternative solution for the resiliency of RTP MIDI streams based on the combined use of redundancy and retransmissions. Our solution is simpler and might be interesting for some scenarios, typically: short grouping times, complex streams or unconventional semantics

Miroirs technologiques pour la pratique instrumentale

La pratique d'un instrument de musique, le travail instrumental, son apprentissage, peuvent être vus comme des activités où le feedback joue un rôle prépondérant. Les technologies actuelles permettent d'envisager l'extension des pratiques instrumentales comme une extension du feedback fournit à l'instrumentiste, aussi bien dans les domaines sonores que visuels. Ce sont ces perspectives nouvelles qui sont présentées, avec leurs implications pour le travail instrumental et leurs applications dans le domaine pédagogique

Gesture cutting through textual complexity: Towards a tool for online gestural analysis and control of complex piano notation processing

International audienceThis project introduces a recently developed prototype for real-time processing and control of complex piano notation through the pianist’s gesture. The tool materializes an embodied cognition-influenced paradigm of interaction of pianists with complex notation (embodied or corporeal navigation), drawing from latest developments in the computer music fields of musical representation (augmented and interactive musical scores via INScore) and of multimodal interaction (Gesture Follower). Gestural, video, audio and MIDI data are appropriately mapped on the musical score, turning it into a personalized, dynamic, multimodal tablature. This tablature may be used for efficient learning, performance and archiving, with potential applications in pedagogy, composition, improvisation and score following. The underlying metaphor for such a tool is that instrumentalists touch or cut through notational complexity using performative gestures, as much as they touch their own keyboards. Their action on the instrument forms integral part of their understanding, which can be represented as a gestural processing of the notation. Next to the already mentioned applications, new perspectives in piano performance of post-1945 complex notation and in musicology (‘performative turn’), as well as the emerging field of ‘embodied and extended cognition’, are indispensable for this project

Syntactical and Semantical Aspects of Faust

International audienceThis paper presents some syntactical and semantical aspects of FAUST (Functional AUdio STreams), a programming language for real-time sound processing and synthesis. The programming model of FAUST combines two approaches : functional programming and block-diagrams composition. It is based on a block-diagram algebra. It has a well defined formal semantic and can be compiled into efficient C/C++ code

Optimized Lock-Free FIFO Queue continued

We have proposed algorithms for lock-free lifo and fifo queue management. This technical report proposes an improved version of the lock-free fifo management algorithm previously defined

MidiShare joins the Open Source Softwares

International audienceMidiShare is a realtime, multi-tasks operating system dedicated to musical MIDI applications. It was awarded the Apple Trophy (1989), the Paris-City price (1990) and more recently, the Max d'Or at the Bourges International Musical Software Competition (1999). Multi-platform support, powerful inter-applications communication, accurate realtime performances are among the significant services provided by the kernel. Freely available on the Internet to developers since several years, MidiShare is now supported by a growing number of projects. Its developers mailing list count 250 members on average. The MidiShare project itself is reaching a state which requires a different management policy: the MidiShare source code is now publicly available to allow collaborative contributions over the Internet. The poster session will present this new project, including changes in the kernel architecture, the source code portability issues and the organization of the collaborative development over the Internet
