A performance data editing system is actualized by a computer system (or electronic musical instrument) which is equipped with a display (14) and a mouse (13). The system initially provides a score window containing various types of execution icon layers (L1-L7) onto which execution icons are attached and arranged in conformity with a progression of a musical tune on a screen of the display. The system provides an icon modify window that allows the user to modify parameters of a specific icon which is selected from among the execution icons attached onto the score window by double clicks of the mouse. Herein, the score window shows a part of a musical score (or a staff notation with notes), while the icon modify window shows an edited portion of the musical score by magnification, wherein a range of execution-related data being edited on the icon modify window is automatically indicated on the musical score of the score window. In addition, modification being effected on a note in the edited portion of the musical score is automatically reflected on note data and/or execution-related data in the performance data. The system also provides an icon select palette that shows latest selections of execution icons which are arranged in an up-to-date manner. The icon select palette shows a number of execution icons which the user frequently or lastly use. Thus, it is possible to improve performability and efficiency in editing performance data by using icons with simple operations and without errors. |
