Abstract
A CPU reads out musical tone control information such as tone color data and effect data from an external storage device or retrieves it via an interface circuit The CPU supplies the musical tone control information to a tone generator and an effect circuit in order to control the tone color of a musical tone signal and the effect added to the signal, using the musical tone control information. When the musical tone control information is not applicable to the tone generator and the effect circuit the information is substituted by musical tone control information applicable to the tone generator and effect circuit and stored in a ROM for the use later on. On a display unit there is displayed the name of substituted tone color data or effect data with information that a substitution has been made. The above facilitates the convenience of the use of musical tone control information such as tone color and effect stored outside when an electronic musical apparatus retrieves the information.
