PROBLEM TO BE SOLVED: To display and input pitch bend data by a value which is easy to understand in terms of music such as a cent value or the number of semitones by converting the value of inputted pitch bend data to a value expressing a pitch variation such as a cent value or the number of semitones based on a set pitch bend range. SOLUTION: A switch detection circuit 2F is provided corresponding to each operator group on a panel switch 2E with ten keys, a character board and other various kinds of switches. A pitch bend range setting operator sets the pitch bend range by assigning a pitch variation with respect to the maximum value of pitch bend data. The pitch variation inputting operator inputs pitch bend data by the cent value. A pitch bend range inputting operator inputs pitch bend data as the value without changing. A display circuit 2H displays pitch bend data as it is, displays as a cent value and displays both of them on a display 2G in parallel. |
