Patent number: 11610570Abstract: An electronic percussion instrument and sound production control method thereof are provided. In an electronic cymbal, the output of a musical sound is controlled in accordance with the results of detection from a strike sensor when the strike sensor detects a strike on a striking surface. While the musical sound is output, if a user touches the striking surface, an electrostatic capacitance sensor outputs an output value in accordance with the contact condition so that the musical sound is attenuated in accordance with the output value while being output. Therefore, the user can attenuate the musical sound being output in accordance with the contact conditions on the striking surface, thereby silencing the musical sound by way of the action similar to that of the acoustic cymbal choke that is the action of touching the striking surface.Type: GrantFiled: June 17, 2022Date of Patent: March 21, 2023Assignee: Roland CorporationInventors: Ryo Takasaki, Yoshiaki Mori, Kenji Morita, Norihiro Yoshikuni

Publication number: 20210366447Abstract: An electronic percussion instrument and a method of detecting a percussion position are provided. The percussion position in a left-right direction is calculated by comparing an added-up value of output values of a first edge sensor with an added-up value of output values of a second edge sensor. Compared with a case where peak values of the first and second edge sensors are used, it is possible to make a great difference between an added-up value in a case where the vicinity of the first edge sensor (the second edge sensor) is percussed and an added-up value in a case where a position away from the first edge sensor (the second edge sensor) is percussed.Type: ApplicationFiled: May 17, 2021Publication date: November 25, 2021Applicant: Roland CorporationInventors: Ryo TAKASAKI, Shun TAKAI

Patent number: 11183161Abstract: The present invention provides a sounding control system capable of performing high-accuracy crosstalk suppression while reducing the processing load on a sound source device. When a first pad (12) vibrates, the first pad (12) generates sound emission data (62a1) that is information instructing a sound source device (11) to produce a sound and crosstalk cancellation determination data (62a2) that is information used for canceling crosstalk, and sends the data to the sound source device (11). The sound source device (11) determines whether or not crosstalk has occurred and controls sound emission using the information.Type: GrantFiled: December 9, 2020Date of Patent: November 23, 2021Assignee: Roland CorporationInventor: Ryo Takasaki

Patent number: 10276141Abstract: Provided are an electronic percussion instrument and a control device thereof. The electronic percussion instrument includes central and peripheral sensors, first and second waiting devices, and a sound production instruction device. When the central sensor detects a strike earlier than the peripheral sensor, the first waiting device performs a first waiting process for a first predetermined time after the central sensor detects the strike. When the peripheral sensor detects a strike earlier than the central sensor, the second waiting device performs a second waiting process for a second predetermined time after the peripheral sensor detects the strike. The sound production instruction device instructs production of a striking sound after the first waiting process of the first waiting device ends, or after the second waiting process of the second waiting device ends if the central sensor has not detected a strike within the second waiting process of the second waiting device.Type: GrantFiled: August 28, 2017Date of Patent: April 30, 2019Assignee: Roland CorporationInventor: Ryo Takasaki

Patent number: 10147409Abstract: Provided is an electronic percussion instrument that is capable of simulating a playing technique for an acoustic percussion instrument. A tubular body part is opened on an axial end surface, and a head is attached to the axial end surface to be struck on the front surface. A capacitance sensor includes an electrode that generates a capacitance with respect to a detected conductor, such as a human body, positioned on the front surface side of the head. Because the capacitance sensor detects a change of a capacitance corresponding to a distance between the electrode and the detected conductor, whether the detected conductor approaches (contacts) the head or presses the head can be determined. As a result, the playing technique for the acoustic percussion instrument is simulated.Type: GrantFiled: March 8, 2018Date of Patent: December 4, 2018Assignee: Roland CorporationInventors: Ryo Takasaki, Norihiro Yoshikuni, Takeshi Osada, Yutaka Morita
