Mechanism that converts a rotary knob (potentiometer) motion on an electric guitar, into a linear sliding motion. The sliding motion can be easily manipulated by the strumming or picking hand of the musician while simultaneously playing the instrument. This mechanism allows an electric guitarist to make sweeping motions with the picking hand while playing to create musical effects with the tone control known as a “wah wah” sound, or “boo wah” sound, and the volume control to create effects known as “volume swells” or volume “tremolo”. The way this mechanism works is by pushing and pulling on a finger loop that is positioned for easy access, the finger loop is fastened to a trolley that has two bearings on it that roll in a track in the main body. The trolley has a gear rack fastened to it and that gear rack rotates a gear that is fastened to the knob stem on the potentiometer, and the action will rotate the potentiometer to its full range. This mechanism can be installed inside of a guitar body with minor modification. It can also be installed easily and without modification to a Telecaster style electric guitar as an external apparatus.

The present invention is a chromatic-emphasis hybrid-diatonic leverless keyboard configured to provide an extension, duplication, or representation of both heptatonic and pentatonic keys on the leverless keyboard. The extension enables the user to shift the physiological center of gravity for the keyboard to the area where pentatonic and heptatonic keys share space and are more isomorphic, thus assisting in gaining and applying understanding of the chromatic equality of the twelve tonalities in standard equal temperament, and in gaining and applying understanding of the one-dimensional nature of music.

An electronic musical instrument includes an operation receiver that receives an input operation and a processor. The operation receiver includes a rotating wheel. The rotating wheel includes a first light emitter that emits colored light. The processor causes, upon the rotating wheel receiving an input operation, the first light emitter to change an emission color from a color at a start of the input operation to a color corresponding to a rotation angle of the rotating wheel having received the input operation.

An electronic musical instrument includes an input device that receives an input operation, a display, and a processor. The processor performs a first process upon duration of a detected continuation of the input operation being a reference time or longer. The processor performs a second process upon duration of a detected continuation of the input operation being less than the reference time. The processor causes the display to display a content from which it is determinable whether or not duration of a detected continuation of the input operation being the reference time or longer.

A microtonal musical instrument interface device between one or more Musical Instrument Digital Interface (MIDI) controllers and one or more musical instruments comprises a housing and a plurality of potentiometers on a surface of the housing. The potentiometers comprise twelve tuning potentiometers constructed and arranged to correspond to notes of a musical scale, each tuning knob for tuning one of the notes; an offset potentiometer for globally tuning all of the notes by a same amount; and a range potentiometer for setting a maximum tuning range of the tuning potentiometers. A microprocessor in the housing modifies a MIDI data stream received from the one or more MIDI controllers for output to the one or more musical instruments according to a position of the potentiometers.

A modular instrument pedalboard is provided. The modular instrument pedalboard provides a plurality removably connectable pods, which may be effect pedal pods, power distribution pods, audio distribution pods, power/audio distribution pods, or a combination thereof. The pods include a base that has a first part of a connector that is adapted to be coupled to a second part of the connector which allows the pods to be connected, rearranged, expanded, contracted, and/or a combination thereof. Further the connectable pods include a circuit board to for parts of one or more audio loops as well as a power bar to transmit audio signals and power between pods.

A pedal unit 10 in one embodiment includes a case 190, a foot lever 100, and an elastic member 155. The foot lever 100 includes a first portion 100r located inside the case 190 and a second portion 100f located outside the case 190. The foot lever 100 is rotatably arranged with respect to the case 190. A center of rotation is located between the first portion 100r and the second portion 100f. The elastic member 155 is arranged within the case 190 and provides a force against the first portion 100r.

The dual keyboard sustain pedal stabilizer is designed for use with a pair of keyboard sustain foot pedals. The dual keyboard sustain pedal stabilizer comprises a stabilizer base, a first pedal-retention area in cooperative engagement with the stabilizer base, a second pedal-retention area in cooperative engagement with the stabilizer base, and an underside of the stabilizer base having a non-slip surface. The first and second pedal-retention areas each include retaining structures proximate to the stabilizer base. The retaining structures enable secure retention of the keyboard sustain foot pedals within the pedal retention area. The dual keyboard sustain pedal stabilizer provides stable footing for the musician on damp floors for both feet while providing a dual keyboard sustain pedal stabilizer that stabilizes either one or two keyboard sustain foot pedals. The dual keyboard sustain pedal stabilizer has no moving parts and is compatible with essentially any keyboard sustain foot pedal.

A musical bodysuit assembly includes a bodysuit that is wearable on a user. A plurality of sound pads is each strategically located on the bodysuit thereby facilitating each of the sound pads to be touched by the user when the user is performing dance moves. Each of the sound pads has a speaker for emitting audible sounds and each of the sound pads has touch sensing capabilities. The speaker in a respective sound pad is turned on to emit an audible sound when the respective sound pad is touched by the user to produce music that corresponds to dance moves performed by the user. A communication unit is in communication with the speaker in each of the sound pads and the communication unit has wireless communication capabilities thereby facilitating the communication unit to download digital audio from a remote data source.
