PURPOSE:To freely execute the setting by a performer by providing plural pieces of breakpoint setting means and a key scaling data arithmetic means for calculating a level of a key based on breakpoint data. CONSTITUTION:By a breakpoint setting means 1, breakpoint data in plural points is set, and stored in a table in a key scaling arithmetic means 2. In the means 2, when an operated key code is obtained from a key 3, first of all, in which position of plural breakpoint trains the key code exists is decided. Subsequently, when the key code exists between two breakpoints, key scaling data is derived from data of its two breakpoints and the key code. The derived key scaling data is outputted to a musical sound forming means 4 and outputted as music. In such a way, a key scaling curve having the degree of freedom can be obtained by a small number of memories. |
