Patent ID: 7605323

Claim:
An ensemble system for reproducing a first sort of tones and a second sort of tones from pieces of audio data and pieces of music data expressing at least pitch and loudness of tones to be produced, respectively, comprising: a sound signal generator producing an audio signal from audio data codes representative of said pieces of audio data and a music signal from quasi audio data codes representative of said pieces of music data and common in formats to said audio data codes, said quasi audio data codes being produced from music data codes expressing said at least pitch and loudness through a modulation to an analog music signal and a conversion from said analog music signal; a volume control manipulator manipulated by a user so as simultaneously to vary the loudness of said first sort of tones and the loudness of said second sort of tones; a volume control signal generator connected to said volume control manipulator, and producing a volume control signal representative of a target value of loudness of both of said first sort of tones and said second fort of tones on the basis of the manipulation of said user; a first volume data changer connected to said sound signal generator and said volume control signal generator, and responsive to said volume control signal so as to vary said pieces of audio data expressing the loudness of said first sort of tones; a second volume data changer connected to said sound signal generator and said volume control signal generator, and responsive to said volume control signal so as to vary said pieces of music data expressing said loudness of said second fort of tones; and a signal-to-sound converter connected to said first volume data changer and said second volume data changer, converting the audio signal output from said first volume data changer to said first sort of tones at said target value of loudness, and producing said second sort of tones on the basis of said music signal output from said second volume data changer at said target value of loudness.
