A musical instrument, for example, a keyboard guitar, includes a body, an elongated neck coupled to the body, neck keys disposed on the elongated neck, and an output for transmitting an electrical signal generated by the musical instrument. Activation of each neck key generates an electrical signal at the output representing a pitch associated with a musical note. The musical instrument may also include body keys disposed on the body, and a strum bar that generates an electrical signal at the output representing a pitch associated with a musical note based on which of the body keys are activated during activation of the strum bar. Further, the musical instrument may include a continuous graphic image spanning the front face of the body and the body keys, forming a continuous pattern that is unbroken across a transition between key surfaces of the body keys and the front face of the body.

According to an embodiment, a signal generation device includes a memory storing a program and a processor communicatively connected to the memory and executing the program to function as a signal generating unit and a sound generation control unit. The signal generating unit generates a sound signal in response to operation of a plurality of operators. The plurality of operators includes a first operator and a second operator. The sound generation control unit controls a sound generation form of a second sound signal generated in response to a second operation of the second operator following a first operation, based on a duration of the first operation of the first operator.

An electronic musical instrument includes an instrument body and a plurality of keys, each of which has an operation surface operated by a player's finger is provided on an external surface of the instrument body. Among the plurality of keys, at least two keys are disposed to be adjacent to each other, and the operation surfaces of the at least two keys are configured to be inclined to descend toward between the at least two keys when viewed from a left-right direction of the electronic musical instrument.

An apparatus and method for pitch-shifting an audio signal with low complexity are disclosed. The method includes identifying a distance between an audio object included in the audio signal and a listener, checking whether the distance between the audio object and the listener decreases, and performing stepwise stretching pitch-shifting of repeatedly using at least one of frequency components of the audio signal when the distance between the audio object and the listener decreases.

The Thumb Bar Controller is a bar that runs the width of the electronic musical keyboard playing area, (plus whatever is needed for the lever attachment), connected by two armsrests just below the top, and approximately one inch away from the keys. It gives the performer control over two (or more) functions with the thumb of the playing hand, that would otherwise require the other hand or foot pedals, allowing a person with the disabilty of one arm/hand, to be as proficient as a person with two. It can be used for controlling pitch bend, modulation, MIDI specification controllers, various electronic controls, and product specific controls.

The bar can be attached in numerous ways, could use a variety of spring type mechanisms to control it. It can be mounted externally or made as an integral part of the keyboard, with openings for the bar connections and movement required.

Provided is a musical instrument controller capable of accurately controlling a musical sound parameter. This musical instrument controller includes: a reception means for receiving, from a musical performance device, a sound emission start signal transmitted on the basis of a musical performance operation; a sensor for detecting an amount of displacement from a reference position; and a control means for generating a control signal on the basis of the amount of displacement from the reference position and transmitting the control signal to a sound generation device. The control means sets the reference position on the basis of the sound emission start signal received from the musical performance device.

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.

An electronic wind instrument and key operation detection method are provided. The electronic wind instrument includes an instrument body and a plurality of keys which have an operation surface operated by a player's finger and are provided on an external surface of the instrument body. Among the plurality of keys, at least two keys disposed to sandwich or surround a predetermined region comprise restriction parts formed on the operation surfaces. The restriction parts restrict escape of the player's finger from between the at least two keys having the restriction parts formed thereon.

An electronic acoustic apparatus includes a control operator, a storage medium, and a processor. The control operator is operable by a user. The storage medium stores a program. The processor is configured to adjust a predetermined control parameter of an audio signal in response to an operation of the control operator. The processor is also configured to determine that the control operator has been operated in a particular operation style different from a normal operation style that adjusts the predetermined control parameter. In response to the operation of the control operator in the particular operation style, the processor is also configured to issue an instruction to execute a predetermined function different from an adjustment of the predetermined control parameter.

An ergonomic, portable, electronic, string-like instrument that utilizes a string-like interface. The string-like interface is tactile for sightless playability and capable of advanced input such as force and pressure sensitivity. The string-like interface functions to select a note, trigger a selected note, select and play a note on the instrument or an external peripheral. The instrument is played using the techniques of multiple stringed instruments and the ergonomics allow the user to hold and handle the device consistent with playing techniques familiar to musicians of multiple instruments. It is internally or externally powered and connects directly to industry-standard musical hardware such as MIDI devices, amplifiers and multi-track recorders.
