Popular types of actuators include solenoids and DC motors. However, the use of industrial strength voice coil actuators provides a compelling alternative given a desirable set of heterogeneous features and requirements that span traditional devices. Their characteristics such as high acceleration and accurate positioning enable the exploration of rendering highly accurate and expressive percussion performances.

This paper combined with its principal reference [1] presents a definitive dataset in the context of snare drum performances along with a procedure for data acquisition, and a methodology for quantitative analysis. The multi-volume dataset contains video, audio, and discrete two dimensional motion data for forty standardized percussive rudiments.

New developments in modeling algorithms are typically presented with single-point, idealized excitations where more complex ones would add vitality to the sounds produced. The 2D waveguide mesh, in particular, can be excited simultaneously at multiple points on a surface, like a physical drum by a hand. The authors present a synthesis system in which this control has been implemented using a 2D pressure sensor, resulting in sounds that capture the some of the salient qualities of hand drumming. A dataset of 2D force measurements from various hand drumming techniques is presented, to be used by researchers in physical modeling synthesis.

In recent years this field has gained interest from the scientific community because of the applicability of this data to the study of climate change and other ecological processes. In this paper we propose the use of tangible interfaces for interactive sonification with a specific example of a multimodal tangible interface consisting of a physical paper map and tracking of fiducial markers combined with a novel drawing interface. The designed interface enables one or more users to specify point queries with the map interface and to specify time queries with the drawing interface. This allows the user to explore both time and space while receiving immediate sonic feedback of their actions. This system can be used to study and explore the effects of climate change, both as tool to be used by scientists, and as a way to educate and involve members of the general public in a dynamic way in this research.

Once we started to use computers in live performance-to interpret abstract gestures and generate sound as a result-the age-old relationship between gesture and result became so blurred as to be often imperceptible. In historical terms, this problem is extremely recent, involving only the last few decades of musical practice preceded by at least thirty thousand years of music-making by conventional (acoustic) means. The aim of this paper is to show how this affects contemporary performance and the relationship between the performer and the audience.

However, providing deep methods of real time musical control remains a major challenge. In this paper we describe our work towards an instrument for percussion synthesis, in which a waveguide mesh is both excited and damped by a 2D matrix of forces from a sensor. By emulating a drum skin both as controller and sound generator, our instrument has reproduced some of the expressive qualities of hand drumming. Details of our implementation are discussed, as well as qualitative results and experience gleaned from live performances.

Both impose rigid constraints on the dynamics of the ensemble situation. Recent developments have shown these models to be end points of a continuum, and the region between is rich and largely unexplored. We examine one sojourn into this realm: Wildlife, which is a work by the authors written for Zeta violin, Radio Drum, and two computers. It is available on CD in the CDCM Computer Music Series (volume 15 from Centaur Records).

This paper describes the challenges faced in using musical robotics in rehearsals and on the performance stage. It also describes the design of custom software frameworks and tools for the variety of composers and performers interacting with the new instruments. Details of how laboratory experiments and rehearsals moved to the concert hall in a variety of diverse performance scenarios are described. Finally, a paradigm for how to teach musical robotics as a multimedia composition course is discussed.

Several basic data reductions are introduced, and the tradeoff between latency and reliability is discussed. An example of the application of this technology to musical performance is presented via the example of the radio drum, a musical controller that produces eight channels of gestural data. The advantages of analyzing this data stream in software are exposed, and future applications of the technology are presented.
