Abstract

A computerized musical instrument system has a processing system for converting multiple modes of music data input into relative rhythm coded data in the format of pitch codes and relative rhythm codes for designating respective types of rhythm elements, including the pitches, as they occur in the beats or other basic music intervals of a music piece. The relative rhythm codes represent the relative proportions by which the designated rhythm elements divide each beat. In a relative rhythm coding mode, pitch and rhythm data are entered via a keyboard and relative rhythm code and control code keys. The music data may also be input in the form of MIDI formatted data, audio or digital sound input, real-time performance (keypress) data, or optically scanned data from printed music notation. The instrument system can provide various forms of outputs including synthesized sound, a display or music notation, stored music data, printed output, and related audio and/or image effects.
