PURPOSE:To convert a basic accompaniment pattern into an accompaniment pattern where the intention of a player is reflected without requiring any large storage capacity by detecting the performance pattern of the player, generating an interval conversion table corresponding to it, and converting the basic accompaniment pattern. CONSTITUTION:The whole operation is controlled by using a central processing unit(CPU) 20, to which a program memory 24, a register group 26, a pattern memory 30, various tables 32, a tempo clock generator 40, a switch group 50, and a tone generator 60 are connected through a two-way bus line 22 in addition to a keyboard circuit 10. The interval conversion of the basic accompaniment pattern is performed by interval conversion data generating means 20, 24, 26, and 32 and interval converting means 20, 24, 26, and 32, so an accompaniment faithful to the intention of the player is played with the small storage capacity. |
