Performance apparatus and tone generation method using the performance apparatus

Abstract

Disclosed is a musical performance device and a musical sound generation method using the musical performance device. A plurality of key switches are arranged to form a plurality of key switch rows, and a plurality of light emitting units are correspondingly arranged with respect to the key switches. For each key switch row, any operation key switch is detected, and according to this detection, the light-emitting units are sequentially illuminated in the following manner: the lighting position is the first predetermined position in the operation key switch and the key switch row to which the operation key switch belongs. To and fro between key switches in one position (eg, one end). In synchronization with lighting of a key switch located at a second predetermined position (eg, the one end) in the key switch row, at least one tone (eg, tone imparted to operating the key switch) given to the key switch row is generated. When the operation of operating the key switch lasts longer than a predetermined time, the light emitting units located within a predetermined range may be lit according to a predetermined pattern, and an effect may be imparted to a tone corresponding to the operation of the key switch.

Description

technical field [0001] The present invention relates to a performance device that receives a plurality of key switch operations by a user and performs performance in response to the user's key switch operations, and a musical tone generating method using the performance device. Background technique [0002] The application program called "TENORI-ON" is known, for example, according to Non-Patent Document 1: "Keitai News" [online], January 16, 2002, ADSCII, [searched on April 1, 2004], Internet< URL: http: / / k-tai.ascii24.com. / k-tai / news / 2002 / 01 / 16 / 632762-000.html? geta >, and [0003] Non-Patent Document 2: "World of Digista Curator" [online], Digital Stadium, Toshio Iwai, Exhibition=TENORI-ON, [searched on April 1, 2004], theInternet<URL: http: / / www.nhk. or.jp / digista / lab / digista_ten / curator.html> [0004] In these performance devices such as portable phones and game devices, point designation inputs input by the user are received on a 16×16 grid arranged ...

AI Technical Summary

Problems solved by technology

Therefore, the same piece of music can only be repeated at predetermined intervals, thereby considerably limiting the degree of freedom in creating a piece of music using conventional performance equipment

In addition, in conventional performance equipment, the same pattern of light-emitting display (i.e., lighting) is also repeated at predetermined intervals; therefore, the degree of freedom regarding the light-emitting display (i.e., lighting) pattern is also considerably limited.

Users may easily get bored with this same music and light display style
