A keyboard unit includes: a key; a displacement member driven directly or indirectly with the key by a pressing operation to be moved; object detection sections including: detection sections, states of which become state change detection state when detecting changes instates of the key and the displacement member; and a generator, in a case that states of all the object detection sections become the state change detection state in the forward stroke of a key pressing operation, obtaining detection results of at least two sets of the detection sections, each set including two object detection sections, selecting at least one of the obtained detection results of the at least two sets of the detection sections, and generating sound generation indication information based on the selected at least one of the detection results.

A keyboard unit includes: a key; a plurality of members which include the key, and each of which has an engaged section for forming an engaged state, the engaged state changed by turning of the key, at least a portion of the engaged section formed of a conductor; a detector which is configured to detect information on the engaged state of the plurality of members by detecting a conduction state between the at least portions of the engaged sections which are in contact with each other; and a determiner which is configured to determine a musical sound parameter based on a detection result of the detector.

A multi-dimensional touch controller, e.g., a musical instrument controller, provides for selectable pad dimensions. The controller includes a matrix sensor for detecting, measuring, and tracking touch gestures. The sensor includes force-sensing resistors arranged in rows and columns. Intersections of the rows and columns are cells that define a unit pad size. The minimum pad size is 11 cell. Double width and/or double length pads can be defined by electrically connecting adjacent columns and/or rows, e.g., to define large 22-cell pads, tall 21-cell pads, and wide 12-cell pads. The electrical connections can be implemented using pairs of multiplexers that allow pairs of rows and/or columns to be selected at once. Virtual pads can be derived in software from switch-defined pads to mitigate a ghost-touch issue characteristic of matrix sensors that otherwise can be exacerbated in certain split configurations with both small and large pads.

A disclosed pedal includes a base, a movable pedal element actuatable by a user's foot, a spring biasing the movable pedal element to a neutral position, a microcontroller, and a sensor unit, such as an integrated accelerometer/gyroscope dual sensor MEMS device carried by the movable pedal element, configured to send data to the microcontroller indicative of actuation of the movable pedal element, such as by sensing acceleration and angular velocity along three perpendicular axes. The microcontroller can generate an output signal as a function of user input to the movable pedal element and in at least two different modes, selected manually and/or automatically, including a switch mode and a continuous modulation mode. In switch mode the output signal is a discrete trigger, and in continuous modulation mode the output signal is continuously variable over a range.

Provided are an electronic musical instrument, a musical sound output method, and a musical sound output program capable of independently generating different musical sounds, that is, a normal musical sound and a special musical sound, through an operation on a single key. In a case where the position of a key becomes equal to or lower than a sound generation start position while the speed of the key is maintained higher than a speed threshold value, the normal musical sound of the key is generated while the special musical sound is not generated. In a case where the speed becomes equal to or lower than the speed threshold value before the position of the key reaches the sound generation start position, the special musical sound of the is generated while the normal musical sound is not generated.
