・Research outline
In recent years, electronic instruments have made remarkable progress with the development of electronic technology. However, compared to a live piano performance, the sound quality and sense of presence are inferior, depending on the device used for playback. On the other hand, when performing on a developed automatic piano, the intensity, length, and tempo of each note must be edited in order to add expression to the piece. Even for a short piece, there are more than 1,000 notes in the score, and editing them one by one requires an enormous amount of time and effort. Therefore, this research aims to develop a PC-based performance information editing support system that can visualize performance information and provide editors with knowledge of musical scores and performance characteristics of editors so that they can edit music more efficiently. The user edits a piece of music via a GUI on a PC. At this time, an automatic conversion function using musical knowledge and user-specific musical features stored in a database in advance reduces the editing work. Recently, we have been developing a system to create a Preference DataBase that stores extracted performance features.
