For several years, we have been developing and studying computer-simulated models of brass instruments including the player's lips. We demonstrate here such a physical model. It is played in real-time with MIDI events. We present recent developments concerning both physical functioning and real-time controls. They result in great improvements of sound(More)
The Brass project aims to deliver software virtual musical instruments (trumpet, trombone, tenor saxophone) based on physical modelling. This requires to work on some aspects of the playability of the models so that they can be played in real time through a simple keyboard : better control of the attacks, automatic tuning, humanization.
Nonlinear Energy Sinks (NES) are used to passively reduce the amplitude of vibrations. This reduction is made possible by introducing a nonlinearly stiffening behavior in the NES, which might lead to an irreversible transfer of energy between the main system (e.g., a building) and the NES. However, this irreversible transfer, and therefore the efficiency of(More)
The aim of this work is to highlight experimentally how inharmonicity of the bore resonance frequencies of an alto saxophone influences the nature of the oscillation regimes. A variable volume branching from the neck of an alto sax at an appropriate position allows one to change the frequency of the first resonance independently from the second. A blowing(More)
