This paper presents results from the development of a digi-tal musical instrument which uses audio feature extraction for the control of sound synthesis. Our implementation utilizes multi-band audio analysis to generate control sig-nals. This technique is well-suited to instruments for which

on the instrument's body which are null in regular circumstances due to selective and exclusive microphone use for the strings. Instrument body percussions are widely used in the acoustic instrumental praxis. They yield a strong potential for providing an extended soundscape via instrument augmentation

percussive mechanism was developed to produce an augmenter of rotary drills. The device was called Percussive Augmenter of Rotary Drills (PARoD). A breadboard PARoD was developed with a 6.4 mm (0.25 in) diameter bit and was demonstrated to increase the drilling rate of rotation alone by 1.5 to over 10 times

Drum controllers designed by researchers and commercial companies use a variety of techniques for capturing percussive gestures. It is challenging to obtain both quick response times and low-level data (such as position) that contain expressive information. This research is a comprehensive study

This paper describes GenJam, a genetic algorithm-based model of a novice jazz musician learning to improvise. GenJam maintains hierarchically related populations of melodic ideas that are mapped to specific notes through scales suggested by the chord progression being played. As GenJam plays its solos over the accompaniment of a standard rhythm section, a human mentor gives real-time feedback, which is used to derive fitness values for the individual measures and phrases. GenJam then applies various genetic operators to the populations to breed improved generations of ideas. 1 Introduction As with most problem-solving activities, musical tasks like composition, arranging and improvising involve a great deal of search. Composers search for the right chords to fit a melody or the right melody to fit a chord progression

This project details the construction and analysis of a percussive agent, able to add timbales accompaniment to pre-recorded salsa music. We propose, implement and test a novel representational structure specific to latin music, inspired by Lerdahl and Jackendo#'s General Theory of Tonal Music
