Performance data search using a query indicative of a tone generation pattern

摘要

A user inputs, as a query pattern, a desired search-object rhythm pattern by operating a rhythm input device. At that time, a determination is made of a style of operation performed by a user on a rhythm input device, such as whether the user has operated a single key or a plurality of keys, or duration or intensity of the operation, and then, a user-intended performance part is identified, on the basis of the determined style of operation, from among one or more performance parts constituting a performance data set (automatic accompaniment data set). For the thus-identified performance part, a rhythm pattern search section searches an automatic accompaniment database for an automatic accompaniment data set including a rhythm pattern that matches the input rhythm pattern (query pattern).

主权项

1. An apparatus for searching through a first non-transitory storage medium for searched-out result part performance data matching an input search query, the first non-transitory storage medium storing therein a plurality of performance data sets each comprising part performance data of one or more performance parts, each of the one or more performance parts being associated with one performance part from among a plurality of different candidate parts of an ensemble, said apparatus adapted to communicate with an operable input device, said apparatus comprising:
a second non-transitory processor-readable storage medium adapted to store instructions: a processor, when executing the instructions, adapted to: determine a style of operation performed on the input device; identify, on the basis of the determined style of operation, at least one of the different candidate performance parts as a search-object performance part; acquire a searching query pattern from the input search query as a search-object query pattern; and search the first non-transitory storage medium on the basis of both the search-object performance part and the search-object query pattern, for the searched-out result part performance data matching the input search query, wherein the searched-out result part performance data matches the identified performance part and matches the acquired searching query pattern.
