This paper describes a novel approach towards automatic evaluation of recorder performance. The processes from finding errors to the formulation of feedback are based on analyses of student performances and experience of recorder teachers. The developed algorithms were implemented in IMUTUS, a prototype practising environment for the recorder [3].
This paper presents some major results from the IMUTUS project 1. IMUTUS was an RTD project that aimed at the development of an open platform for training students on the recorder. The paper focuses on one of the most important and innovative parts of the IMUTUS system, the practicing environment. This environment integrates technological tools for the(More)
Skipproof is an application that emulates a typical disc jockey (DJ) setup of turntable plus mixer and also allows high-level control of the playing style known as scratching. High-level control in this case means performing with modeled, complex DJ gestures through simplified actions: For instance, letting a single movement produce a sound that normally(More)
IMUTUS is a European project that aims at the development of an open platform for training students on non-MIDI musical instruments, as well as to acquire theoretical music knowledge. The project involves many components oriented towards a new approach of music learning. After a brief overview of the system, the performance evaluation module and the music(More)
This paper reports on two Short-Term Scientific Missions (STSM) in the ConGAS European Cost Action. Several sound models and (musical instrument) interfaces were combined to study how DJ gestures of scratching can be applied to new situations. In one experiment, the gestures were used to control a physics-based model of friction sounds, for instance to(More)
This article deals with the popular and rarely studied art form of manipulating a vinyl record by rhythmically dragging and pushing it, commonly labelled " scratching ". With sufficient practice, a Disc Jockey (DJ) can have great control over the sound produced and treat the turntable as an expressive musical instrument. Even though a digital-based model of(More)
The art form of manipulating vinyl records done by DJs is called scratching, and has become very popular since it started in the seventies. Turntables are commonly used as expressive musical instruments in several musical genres. This phenomenon has had an serious impact on the instrument-making industry, as the sales of turntables and related equipment(More)
This paper deals with the question of how the development of new musical artifacts can benefit from deeply engaging with contemporary musical practice. With the novel ideas produced by the NIME community manifested in musical instruments in continuous use, new research questions can be answered and new sources of knowledge can be explored. This can also be(More)
