Abstract:
1. An ensemble system for concurrently producing a first sort of tones and a second sort of tones, comprising: a first sound source for producing said first sort of tones; a second sound source for producing said second sort of tones; a first data source storing pieces of music data information representative of said first sort of tones; and an ensemble controller connected to said first sound source, said second sound source and said first data source, and achieving at least first, second and third tasks for producing said first sort of tones concurrently with said second sort of tones, said ensemble controller determining a pitch of one of said tones of said second sort actually produced by said second sound source in said first task, said ensemble controller determining a data read-out speed on the basis of a ratio between said pitch of said one of said tones and a pitch of a corresponding tone of said first sort to be equivalent in pitch to said one of said tones through an analysis on selected ones of said pieces of music data information in said second task for adjusting said tones of said first sort to pitches different from the pitches represented by said pieces of music data information by a predetermined offset value, said ensemble controller transferring said pieces of music data information from said first data source to said first sound source at said data read-out speed in said third task so that said first sound source produces said tones of said first sort concurrently with said tones of said second sort produced by said second sound source.
