  • Patent number: 9214145
    Abstract: 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.

  • Patent number: 8053658
    Abstract: 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.

  • Patent number: 8026437
    Abstract: When the on-on time between Note 1 and Note 2 is shorter than the double stop judgment time JT, as shown in FIG. 3A, the mode is changed from Unison 1 to Unison 2. When note-on information of Note 1 is inputted at time t1, the parts 1-4 are assigned to Note 1, and simultaneously start sound generation at pitch n1, as shown in FIG. 3B. Next, when note-on information of Note 2 at pitch n2 lower than Note 1 is inputted at time t2, the mode is switched to Unison 2. Part 1 (with the timbre being trumpet) and Part 2 (with the timbre being clarinet) which are higher in the pitch order are assigned to Note 1, and continue generating the musical sound at pitch n1 of Note 1, and Part 3 (with the timbre being alto saxophone) and Part 4 (with the timbre being trombone) which are lower in the pitch order are assigned to Note 2, stop the sound generation at pitch n1, and start sound generation at pitch n2 of Note 2.
