Patent number: 11942066Abstract: Provided is a transmitter for musical instrument and a mode switching method thereof. A transmitter for musical instrument which is mounted on an electric guitar determines the electric guitar is in a not-in-use state when a continuation time in which a square sum of accelerations output from a three-axis acceleration sensor is smaller than a power-saving threshold value is longer than a power-saving transition time, and the transmitter transitions from a normal mode to an energy-saving mode. On the other hand, when the accelerations in the energy-saving mode becomes equal to or greater than a release threshold value from a state of being smaller than the release threshold value or becomes equal to or smaller than the release threshold value from a state of being greater than the release threshold value, the electric guitar is returned from the energy-saving mode to the normal mode.Type: GrantFiled: January 8, 2018Date of Patent: March 26, 2024Assignee: Roland CorporationInventors: Hiroshi Yamate, Shinji Asakawa, Masato Ueno, Ryo Susami

Patent number: 9395235Abstract: Based on a peak level of a waveform in a predetermined period after the input of the waveform started and a value indicative of the degree of change in the waveform in the predetermined period, a judging device determines whether the waveform is caused by a strike. Thus, the peak level and a value indicative of the degree of change in the waveform are considered to determine whether the waveform is caused by a strike. A waveform with a small peak level caused by a weak strike is not erroneously detected as noise, while accurate detection of strikes can be obtained.Type: GrantFiled: December 5, 2012Date of Patent: July 19, 2016Assignee: Roland CorporationInventor: Ryo Susami

Patent number: 9082335Abstract: A display control apparatus is provided. Every time when the level of the signal is obtained, the peak display with respect to the level of the signal is initiated by the first peak display control unit in a predetermined display manner in the display position obtained by the peak position obtaining unit. On the other hand, the previous peak displays being displayed according to the level of the signal obtained at a previous time and a time before the previous time is continued, and the display manner of the previous peak display being displayed is changed according to the second peak display control unit. Accordingly, while one and more than one level are simultaneously displayed on one display device, the temporal sequence of the levels, which is simultaneously displayed with different display manners, can be recognized by the user.Type: GrantFiled: December 11, 2012Date of Patent: July 14, 2015Assignee: ROLAND CORPORATIONInventor: Ryo Susami

Patent number: 8723014Abstract: A musical tone control device capable of generating a hi-hat sound intended by the performer operates such that, when striking surface position information corresponds to a first position, instructions are provided to stop generating a musical tone with a first timbre (or that satisfies another predetermined condition), when the striking surface position has reached a predetermined second position higher than the first position after instructions are provided to generate the musical tone. Since, the performer's intention is reflected in the transition state of the striking surface position, a musical tone according to the performer's intention can be generated.Type: GrantFiled: October 12, 2012Date of Patent: May 13, 2014Assignee: Roland CorporationInventor: Ryo Susami

Patent number: 8648243Abstract: A tone generation control device sets a setting value for crosstalk cancellation. When vibration generated in a target striking surface is detected, a value indicative of the degree of crosstalk that the target received from comparison striking surfaces is calculated. The calculated value is displayed regardless of whether a tone generation instruction has been output. Meanwhile, setting values used for crosstalk cancellation for the respective striking surfaces are also displayed. Therefore, the user can observe and understand as to whether the vibration generated at the target is vibration caused by crosstalk received from the comparison striking surface, such that setting values to be used for crosstalk cancellation can be suitably set.Type: GrantFiled: January 10, 2013Date of Patent: February 11, 2014Assignee: Roland CorporationInventor: Ryo Susami

Patent number: 7820903Abstract: An electronic percussion instrument can carry out the control of the musical tones that is intended by the performer. The instrument includes electronic controls that set a vibration flag when the instrument is struck and a determination is made as to whether or not a timer has timed a specified time period. If the timer has timed the specified time period, the vibration flag that is stored in the flag memory is reset. If the time period has not been reached, the displacement sensor processing ends and the routine returns to the main processing. In those cases where the vibration flag is not set, or in those cases where the resetting of the vibration flag has completed, a determination is made as to whether or not the upper cymbal has shifted from an open position to the closed position.Type: GrantFiled: September 5, 2008Date of Patent: October 26, 2010Assignee: Roland CorporationInventor: Ryo Susami
