IMUTUS is a European project that aims at the development of an open platform for training students on nonMIDI 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 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. 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)
For 30 years Disc Jockeys have been expressing their musical ideas with scratching. Unlike many other popular instruments, the equipment used for scratching is not built as one single unit, and it was not intended to be a musical instrument. This paper gives an overview of how DJs use their turntable, vinyl record and audio mixer in junction to produce(More)
This paper describes a project started for implementing DJ scratching techniques on the reactable. By interacting with objects representing scratch patterns commonly performed on the turntable and the crossfader, the musician can play with the DJ techniques and manipulate how they are executed in a performance. This is a novel approach to the digital DJ(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)
We performed an experiment to investigate differences between persons with and without hearing losses when playing a novel audio-based game on a tablet computer, and how persons with hearing losses appreciated the game when they played it with three different types of sound material---speech, music, or mixed speech and music. We analyzed game log files and(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)
