A data using device includes: a data storage part storing pieces of data used for the predetermined process; a user storage part storing a first user identification information; an authentication data acquisition part; a user acquisition part acquiring a second user identification information from the external apparatus; a user determination part; an authentication storage processing part storing the authentication data such that the authentication data is available for the predetermined process when the user determination part determines that the first and second user identification information match each other or when the first user identification information is not stored; a user deletion part deleting or instructing a user to delete the first user identification information when the first and second user identification information do not match each other; and a data use prohibition part prohibiting use of the authentication data when the first user identification information is deleted.

Data using device and data using method

A musicality information provision method includes acquiring first performance data from a performance of a given composition, calculating, with respect to a combination of a plurality of parameters indicating musicality, which are included in the first performance data, respective distances between the first performance data and a plurality of sets of second performance data that are acquired from performances of the given composition and that are compared with the first performance data, and outputting determination information for determining the musicality of the first performance data, the determination information including information indicating the distances.

Musicality information provision method, musicality information provision apparatus, and musicality information provision system

Provided are an electronic musical instrument, computer storage device, and method for generating tone. A sound source in an electronic musical instrument generates a first tone at a first pitch in response to a first tone generation instruction received by an input device of the electronic musical instrument. A second tone generation instruction is received to generate a second tone at a second pitch while generating the first tone at the sound source. A determination is made of a pitch difference of the first and the second pitches. The sound source is controlled to generate the second tone and to not generate the first tone in response to determining that the pitch difference does not exceed a predetermined number of tones. The sound source is controlled to generate the second tone in response to determining that the pitch difference exceeds the predetermined number of tones.

Electronic musical instrument to generate musical tones to imitate a stringed instrument

An electronic musical instrument includes: an input device that inputs a sound generation instruction to start generating a musical sound and a stop instruction to stop the musical sound; an on-on time timer device that measures a time difference between a first and second sound generation instructions; a gate time timer device that measures a time difference between the second sound generation instruction and a stop instruction; an attack characteristic setting device that sets an attack characteristic of the musical sound to have a shorter attack time as the time difference measured by the on-on time timer device becomes shorter; and a release characteristic setting device that sets a release characteristic of the musical sound generated to have a shorter release time as the time difference measured by the gate time timer device becomes shorter.

Electronic musical instrument using on-on note times to determine an attack rate

When the on-on time between Noteand Noteis shorter than the double stop judgment time JT, as shown in FIG.A, the mode is changed from Unisonto Unison. When note-on information of Noteis inputted at time t, the parts-are assigned to Note, and simultaneously start sound generation at pitch n, as shown in FIG.B. Next, when note-on information of Noteat pitch nlower than Noteis inputted at time t, the mode is switched to Unison. Part(with the timbre being trumpet) and Part(with the timbre being clarinet) which are higher in the pitch order are assigned to Note, and continue generating the musical sound at pitch nof Note, and Part(with the timbre being alto saxophone) and Part(with the timbre being trombone) which are lower in the pitch order are assigned to Note, stop the sound generation at pitch n, and start sound generation at pitch nof Note

Electronic musical instrument generating musical sounds with plural timbres in response to a sound generation instruction

FIG.A indicates a case where Noteonly is depressed, and the four parts are assigned to Note. FIG.B indicates a case where Notewith a lower pitch than Noteis further depressed, wherein Partand Partare assigned to Note, and Partand Partare assigned to Note. FIG.C indicates a case where Notewith a lower pitch than Noteis further depressed, wherein Partis assigned to Note, Partis assigned to Note, and Partand Partare assigned to Note. FIG.D shows a case where Notewith a lower pitch than Noteis further depressed, wherein Partis assigned to NotePartis assigned to Note, Partis assigned to Note, and Partis assigned to Note. FIG.E shows a case where the number of notes is greater than the number of parts, and where Notewith a lower pitch than Noteis depressed, wherein Partis assigned to Noteand Note, Partis assigned to Note, Partis assigned to Note, and Partis assigned to Note. In this manner, parts are generally equally assigned to notes.
