O presente texto pretende, de uma forma resumida, e consequentemente não exaustiva, dar ao leitor uma perspectiva sobre o que é a digitalização do som e sobre as possibildades oferecidas por essa forma de representação sonora nos dias de hoje. Após uma breve descrição do processo de digitalização, será feita uma descrição das novas possibilidades que se abrem para análise e manipulação do som, assim como das vantagens na representação digital do som em projectos artísticos interdisciplinares servindo como veículo de interactividade entre as artes digitais.

This paper presents the program in electronic music composition and musical production at the School of the Arts of the Polytechnic Institute of Castelo Branco (http://www.esart.ipcb.pt). This study program offers a 1st cycle degree and is functioning since the academic year of 2005/2006. At the conference, we will present the curriculum of the program, some recent work by the students, and the next phase in the program development, which includes making contacts with people and institutions to further develop the program through ERASMUS exchanges of faculty and students, hiring of new faculty members, and eventual creation of an European partnership for a 2nd cycle degree. Keywords: New academic programs in electronic music, electronic music, musical production, multimedia.

This paper describes a contour-based algorithm for the real- time automatic generation of jazz walking bass lines, fol- lowing a given harmonic progression. A brief description of the walking bass procedure will be presented, and also a brief survey on some common implementations and tech- niques. This algorithm was implemented in the Max/MSP graphi- cal programming environment.

This paper presents a dynamic interface and voicing algo- rithm for real-time performance of jazz piano comping. Starting with a given song with a predefined harmonic progression, the algorithm calculates and maps an array of chord voicings to a virtual piano keyboard that can be played in real-time with any physical multi-touch input device like an iPad or computer keyboard. By taking care of the note selection for the voicings, the interface pro- vides a simplified and intuitive way to play sophisticated voicings, while leaving the control over the performance aspects like timing, register, wideness and density to the user.
