Abstract
Each musical performance data of a source file includes time data, note data indicative of music sound start or music sound stop at a moment indicated by the time data, and accent data indicative of sound velocity. The time data, the note, and either the music sound start or the music sound stop are recorded in a first recording area in accordance with the time data. The accent data is recorded in a second recording area. The second recording area is separated from the first recording area. The recorded data in the first and second areas are combined to obtain a target file. And, the another file is recorded in a recording medium. A reproducing apparatus reproduces the recorded musical performance data. The musical performance data are decoded and temporarily stored into a storage medium. The decoded and temporarily stored data are controlled such that the note and accent data are reproduced before the control data. A sound source reproduces the controlled musical performance data and generates music sounds in accordance with the reproduced data.
