Patent number: 9214145Abstract: 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.Type: GrantFiled: February 23, 2012Date of Patent: December 15, 2015Assignee: ROLAND CORPORATIONInventors: Mizuki Nakagawa, Ikuo Tanaka, Shun Takai

Patent number: 8026437Abstract: 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.Type: GrantFiled: May 18, 2009Date of Patent: September 27, 2011Assignee: Roland CorporationInventors: Ikuo Tanaka, Yoshinori Iwamoto
