Provided are an electronic percussion instrument and a hit detection method. An overhang portion constituting the outer edge part of an edge frame is positioned further radially outward than the outer edge of a bow frame. Consequently, when the overhang portion is hit, the vibration resulting from the hit is detected by an edge sensor attached to the edge frame. In this way, it is possible to detect whether the overhang portion (the edge portion of an electronic cymbal has been hit by means of vibration detection by the edge sensor instead of by means of pressure detection by a sheet sensor.

Rather than a vertical see-saw type of volume pedal for a guitar, a foot-controlled volume pedal for a guitar has a foot pad that swivels in a generally horizontal arc around a pivot point. The foot pad has a pointer at its far end (away from the pivot point) that points to the volume numbers 0-10. The player's heel will generally be over, or close to, the pivot point, and the foot covers the pad or part of the pad. The pivot point comprises a rotatable shaft that is coupled to a smaller rotatable shaft of a conventional potentiometer, by friction, gears, or a belt, for controlling the volume into the guitar amplifier. The rotation ratio of the two shafts may be, for example, 6:1. The swivel arc may be large (e.g., 5-8 inches) so a precise volume can be set between 0-10.

Battery powered devices are provided with electrically isolated outputs. One exemplary battery device comprises at least one battery; and control electronics configured to provide a plurality of outputs from one of the at least one battery, wherein the plurality of outputs comprise at least one output that is electrically isolated from at least one other output of the plurality of outputs that each provide power to one or more of a plurality of loads. In another exemplary battery device, the control electronics are configured to provide a plurality of outputs from one of the at least one battery, and further comprises a housing assembly comprising (i) at least two surfaces, wherein the at least two surfaces have a space therebetween configured to house the control electronics and the at least one battery; or (ii) a tubular structure configured to house the control electronics and the at least one battery.

A reproduction control method, which is executed by a computer, includes detecting a first state in which an object is separated from an operation surface by a prescribed distance and a second state in which the object is in contact with the operation surface, initiating sound reproduction at a first time point at which the first state is detected, continuing the sound reproduction from the first time point to a third time point which is subsequent to a second time point at which the second state is detected, and controlling a change in a feature amount of a sound during a first time period from the first time point to the second time point.

A displacement sensor includes: a detectable portion: including a first coil; and being disposed on a movable member that is displaceable in response to an operation; and a signal generator: including a second coil that opposes the first coil; and being configured to generate a detection signal based on a relative position between the first coil and the second coil. A first distance from a first end of the first coil to a second end of the first coil in a first direction differs from a second distance from a third end of the first coil to a fourth end of the first coil in a second direction perpendicular to the first direction when the first coil is viewed in plan view.

A pedal device receives a connection signal transmitted from headphone to establish first communication that is communication with the headphone. Then, in a case where the first communication has been established, the pedal device transmits the connection signal including information indicating that communication with the headphone has been established. By receiving the connection signal from the pedal device, a portable terminal establishes second communication that is communication with the pedal device. In a case where the received connection signal includes information that the communication with the headphone has been established, the portable terminal may determine that communication establishment between the pedal device and the headphone has been completed.

The presence of saxophonists furthering their musical horizons by playing keyboard instruments inspires the invention of a novel device to connect a light-weight keyboard or MIDI grid controller to a saxophone to facilitate the convenient and rapid switching between playing either instrument. Battery power and Bluetooth technology combine with innovations in plastics technology to facilitate the creation of strong, lightweight structures to facilitate such a device. With the addition of looping software on a laptop computer, a saxophonist so equipped can create music to accompany themselves, obviating the need for other musicians to function as a musical ensemble. This innovation may be the harbinger for other musicians on other single note instruments—trumpet, trombone, violin, etc. to join this trend using either instrument-attached, strap-on or wearable keyboards. This could blend the boundaries between acoustic and electronic instruments, and increase the enjoyment and musical enrichment of musicians and audiences alike.
