PURPOSE:To listen to a played musical sound which is rich in variation by generating plural pieces of pitch information and generating musical sound signal having respective represented pitches. CONSTITUTION:A musical sound signal generating circuit 41, an automatic accompaniment sound signal generating circuit 42, and an external input/output circuit 50 are connected to a bus 30. Further, a microcomputer 60 which controls the circuits is connected and consists of a program memory 61, a CPU 62, a tempo oscillator 63, a working memory 64, a control parameter memory 65 for timbre, etc., a chord detection table 66, a chord constituent sound table 67, an inverted chord number table 68, and a performance data memory 69. Chords represented by chord information generated by a chord information generating means in order are inverted according to the operation of operation elements 25 - 27 and sounded. Consequently, the states of chords are varied variously to play a musical sound which is rich in variation. |
