<P>PROBLEM TO BE SOLVED: To provide a recorder whose manufacturing cost can be reduced, and in which data control for undo can be simplified. <P>SOLUTION: In the recorder, a musical sound before editing and a musical sound after editing are divided into block units, respectively to be stored in a track 0 and a track 1 each of which consists of a plurality of blocks. As a result, although execution of undo is limited to one time, the storage capacity for storing the musical sounds is restricted to a small capacity and the manufacturing cost of the recorder is reduced. Moreover, in the recorder, since the musical sound before the editing can be read out, by only returning the selection information of a selection flag to an original state according to write-in information stored in a current flag, data control for undo is simplified. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
