摘要： A keyboard device for a keyboard instrument, capable of causing a cushion to properly function while suppressing generation of noise when a hammer contacts the cushion. The hammer is vertically pivotally moved in a manner interlocked with key depression. The cushion is provided below the hammer. In a key-released state, a contact portion of the hammer is placed on the cushion, and when the hammer pivotally moved upward by key depression returns to its original position by key release, the contact portion contacts the cushion from above. The contact portion is formed to be inclined in the front or rear direction with respect to the upper surface of the cushion when contacting the cushion. The hammer has a deformation suppressing portion provided on the contact portion and/or its vicinity, for suppressing deformation of the cushion in the front-rear direction when contacting the cushion.

摘要： An electronic signal processor for processing signals includes a complex first filter, one or more gain stages and a second filter. The first filter is characterized by a frequency response curve that includes multiple corner frequencies, with some corner frequencies being user selectable. The first filter also has at least two user-preset gain levels which may be alternately selected by a switch. Lower frequency signals are processed by the first filter with at least 12 db/octave slope, and preferably with 18 db/octave slope to minimize intermodulation distortion products by subsequent amplification in the gain stages. A second filter provides further filtering and amplitude control. The signal processor is particularly suited for processing audio frequency signals.

摘要： A control unit for a musical instrument having a keypad and/or touch pad areas for controlling a signal processing unit. The control unit is preferably formed in a thin and elastic layered structure whereby touching electrode surfaces of the structure generates a charge, voltage or capacitance that is subsequently processed. The control unit includes a surface element, whereby settings and values of the signal processing unit can be changed and controlled by a user applying physical contact to the surface element. A user control device is further coupled to the control unit, and is operable under at least two forms of operation, and wherein the user control device is configured to (1) select an acoustic parameters and (2) adjust the selected acoustic parameter.

摘要： When an array of proximity sensors is used as a keyboard, it can provide an ambiguous output if a user's finger overlaps several keys or if liquid is spilled on the keyboard. This ambiguity is reduced by an iterative method that repeatedly measures a detected signal strength associated with each key, compares all the measured signal strengths to find a maximum, determines that the key having the maximum signal strength is the unique user-selected key and then suppresses or ignores signals from all other keys as long as the signal from the selected key remains above some nominal threshold value.

摘要： A method for the use of the white keys of a musical keyboard such as a MIDI keyboard for the playing a selected scale whereby all while keys of the keyboard are remapped to the selected scale such that adjacent keys of the keyboard can be used to play adjacent notes of the selected scale. There is also disclosed a method for providing a functional aspect to at least one black key of a musical keyboard such as a MIDI keyboard, wherein upon a key of the keyboard being pressed, a first check is conducted to determine if a user has activated the selected scale setting; and if the selected scale function has been activated, a second check is conducted to determine if the key is a black key or a white key. If the key is a black key a second lookup table is checked based on a MIDI message for the black key to determine a corresponding functional aspect corresponding to the black key.

摘要： A key weight capable of being easily mounted in a key for a keyboard instrument and being positively prevented from falling off the key. The key weight is mounted in the key by being inserted from outside into a weight-accommodating portion of the key, and includes a block-shaped weight body portion, protrusions that are formed on an insertion leading end of the weight body portion into the weight-accommodating portion and are elastically deformed by a reaction force from a far-side wall surface of the weight-accommodating portion when the weight body portion in a state in contact with the far-side wall surface during mounting of the key weight is pushed into the weight-accommodating portion, and latched portions that are formed on side surfaces of the weight body portion and are latched with side walls of the weight-accommodating portion.
