Abstract
A harmony tone generating apparatus receives a voice wave signal bearing musical tone pitches such as a singer's or a speaker's human voice signal and a musician's instrumental voice signal, and plural kinds of performance data, each representing a musical note pitch, from plural kinds of performance sources. The latest received performance data from among the plural performance sources is captured and supplied to a harmony tone data generator, which in turn generates harmony tone data defining a tone pitch which is determined by the note pitch represented by the performance data. As the harmony tone data generator includes a limited number of data generation-channels, the limited number of the latest captured performance data pieces are assigned thereto for harmony data generation, truncating the oldest supplied performance data for new data assignment, where there is no empty channel left and newly captured performance data is supplied. A harmony voice signal will be produced with a tone pitch determined by the captured performance data and in a voice determined by the voice of the received voice wave signal. The original voice wave signal may be sounded in audible voice, and the performance data may be sounded in audible music.
