1. An apparatus for creating musical performance data according to operations of a user, comprising: a screen display section that displays an input screen having a data input area for inputting musical performance data, the input screen simulating a staff notation; a position indication section operable when a first operation is taken by the user for indicating a position on the data input area; a display enlargement section operable when a second operation is taken eventually by the user for enlarging a local portion of the data input area around the indicated position and displaying the enlarged local portion over the data input area such that the enlarged local portion provides a zoomed view of the staff notation around the indicated position, thereby allowing the user to take a supplemental first operation on the enlarged local portion more easily than the first operation such that the position indication section responds to the supplemental first operation for indicating a position on the enlarged local portion of the data input area; and a data input section that is responsive to a third operation of the user for inputting musical performance data corresponding to the position indicated according to the first operation when the supplemental first operation is not taken by the user, or corresponding to the position indicated according to the supplemental first operation when the supplemental first operation is eventually taken by the user.
