PURPOSE:To set preset values as the values of parameters for controlling a musical sound individually, parameter by parameter and to facilitate the setting operation. CONSTITUTION:At an operation panel part 2, operation element groups each consisting of a UP/DOWN operation element for increasing and decreasing the value of a parameter and a PRESET operation element are arranged as many as the parameters while being made to correspond to the parameters. When a user presses the PRESET operation element, a preset value supply means 21 reads the preset value of the corresponding parameter among preset data stored in a preset memory 6 and supplies it to a work memory 5 to rewrite the corresponding parameter among parameters stored in the work memory 5 into the preset value. |
