In recent years, with the development of electronic technology, electronic musical instruments have made remarkable progress. However, compared with the performance of the acoustic piano, the current situation is that it is inferior in terms of sound quality and realism, depending on the device to be reproduced.

For those reasons, we have developed the Automatic Piano, which is consisted of a acoustic piano and actuators specially developed for pressing keyboard. You can see the actual performance from the following movie.

On the other hand, when playing with the automatic piano, you need to edit sound strength, length, tempo, etc. for each note in order to add expression to the song. Even with short songs, there are over 1000 notes on the score, and it takes a huge amount of time and effort to edit them one by one.Therefore, in this research, in order to make editing of music more efficiently, we develop the support system that can visualize performance information, can teach us about the musical knowledge and pianist’s performance characteristics.
