Patent number: 5069107Abstract: A breath detection signal from a breath sensor section is converted to a digital breath detection signal, and when the value of the detection signal exceeds a preset value, a tone is generated. After the tone generation, a tone parameter of the tone being generated is controlled according to the value of said digital breath detection signal. When a predetermined period of time is elapsed from an instant when the digital breath detection signal exceeds a preset signal, initial breath data is generated in correspondence to the breath detection signal or preset value at that instant. The tone parameter of the tone at the time of the tone generation is controlled according to initial breath data. After the generation of the tone, the tone parameter of the tone being sounded is controlled according to after-breath data corresponding to the breath detection signal.Type: GrantFiled: February 6, 1990Date of Patent: December 3, 1991Assignee: Casio Computer Co., Ltd.Inventor: Shigeo Sakashita

Patent number: 5010801Abstract: An electronic musical instrument according to the present invention is applicable to musical instruments such as electronic wind instruments, electronic rubbed string instruments and electronic stringed instruments. Parameters of a musical tone to be generated are individually and independently altered and controlled in accordance with control data corresponding to a variation tendency of performance-input data which is detected by a performance input detection section and alters with time. And in accordance with a variation tendency per a predetermined period of time of breath operation intensity and/or lip operation intensity, parameters of the musical tone having a designated pitch are individually and independently altered and controlled.Type: GrantFiled: May 16, 1989Date of Patent: April 30, 1991Assignee: Casio Computer Co., Ltd.Inventor: Shigeo Sakashita

Patent number: 4993307Abstract: A present electronic musical instrument is applied to an electronic wind instrument and an electronic keyboard instrument. At least one piece of pitch difference data representing an arbitrary pitch difference with respect to a first pitch that is to be designated by a pitch designation section is stored in a memory section. Before or during a musical performance, the pitch difference data is selected, and an original tone having the first pitch and a coupler tone having a pitch different from the first pitch are simultaneously generated with a pitch difference corresponding to the selected pitch difference data. The timbres of the original tone and the coupler tone may be set different from each other.Type: GrantFiled: March 15, 1989Date of Patent: February 19, 1991Assignee: Casio Computer Co., Ltd.Inventor: Shigeo Sakashita

Patent number: 4939975Abstract: The present electronic musical instrument can apply to various electronic musical instruments, such as an electronic wind instrument, electronic keyboard instrument and electronic string instrument. Pitch alteration width data with a predetermined pitch difference with respect to a tone being presently generated is stored in advance in a memory section, and by alternately performing the following two operations thereby to ensure a trill performance with a pitch having an arbitrary pitch alteration width by a simple pitch alteration operation. (1) A predetermined musical tone is generated at the presently-designated pitch by the pitch designation operation executed with respect to a pitch designating section. (2) A predetermined musical tone is generated at a pitch higher or lower than the presently-designated pitch, in accordance with the pitch alteration width data, by the pitch alteration designating operation executed with respect to a pitch alteration designating section.Type: GrantFiled: January 24, 1989Date of Patent: July 10, 1990Assignee: Casio Computer Co., Ltd.Inventor: Shigeo Sakashita

Patent number: 4919032Abstract: A pitch of a musical tone to be generated based on a breath sense signal detected by a breath sensor is set by a pitch setting operation of a pitch setting section. When the pitch setting operation is changed during generation of the musical tone based on the breath sense signal, pitch data corresponding to a pitch newly set by the change in the pitch setting operation is output upon elapse of a predetermined time from the timing of the change. The pitch of a musical tone being generated is altered to the pitch according to the new pitch data upon elapse of the predetermined time.Type: GrantFiled: December 20, 1988Date of Patent: April 24, 1990Assignee: Casio Computer Co., Ltd.Inventor: Shigeo Sakashita

Patent number: 4683794Abstract: A plurality of rhythm designation data are supplied from a CPU, and latched in corresponding individual latches which are responsive to channel data from a decoder. The latched data are supplied to an address ROM in response to corresponding channel timing signals, wherein start and end address data for a rhythm waveform data ROM are read out from the address ROM. If the rhythm designation data latched in one of the individual latches is the same as in another one of the latches, the same rhythm is sounded concurrently and without sound interruption.Type: GrantFiled: December 30, 1985Date of Patent: August 4, 1987Assignee: Casio Computer Co., Ltd.Inventor: Shigeo Sakashita

Patent number: 4648115Abstract: An input musical tone signal is amplified by a first VCA and then supplied to second and third VCAs. The second and third VCAs are controlled by sine-wave signals which have a 180.degree.-phase difference. Musical tone signals, which have been so controlled that a pan-pot may move right and left, are supplied to right and left loudspeakers. The first VCA is controlled by a sine-wave signal whose phase is different by 90.degree. from the phases of the signals supplied to the second and third VCAs. The volume of a composite musical tone made up of the tones generated by the loudspeakers is thereby controlled, thus also moving the pan-pot to the front and rearward.Type: GrantFiled: September 11, 1984Date of Patent: March 3, 1987Assignee: Casio Computer Co., Ltd.Inventor: Shigeo Sakashita
