A conversion-to-note apparatus includes: a key which is operated by a user; and a processor. The processor obtains, from a memory, first information and second information. The first information is information to associate a key operation on the key with an open/close state of a tone hole or virtual tone hole. The second information is information to associate the open/close state of the tone hole or virtual tone hole with a note. Further, the processor identifies, based on the first information, the open/close state of the tone hole or virtual tone hole for the key operation detected. Further, the processor determines, based on the second information, the note for the identified open/close state of the tone hole or virtual tone hole.

An electronic musical instrument including a musical instrument body which is supported by first finger of a hand of an instrument player and at least one finger other than the first finger, scale keys which are provided at positions that are contacted with fingers other than the first finger on one surface of the musical instrument body, and each of which specifies a scale of a musical sound, a touchpad which is provided in an area that is contacted with the first finger on an other surface of the musical instrument body, and includes a sensor that has a planar detection area for detecting a contact position of the first finger, and a processor which controls emission of the musical sound whose scale has been specified by the scale key in accordance with the contact position of the first finger detected by the touchpad.

This invention involves the field of tactile control of electronic devices using a sensor that transduces both air pressure and device positional orientation into a set of digitally encoded commands. The invention involves using as input the physical action taken on a musical instrument and generating control information using that input.

A detection device including n number of sensors arrayed in a direction, in which n is an integer of 3 or more and from which (n1) pairs of adjacent sensors are formed, and a processor which determines one specified position in the direction based on output values of the n number of sensors, in which the processor calculates (n1) sets of difference values each of which is a difference between two output values corresponding to each of the (n1) pairs of sensors, and determines the one specified position based on the (n1) sets of difference values and correlation positions corresponding to the (n1) sets of difference values and indicating positions correlated with array positions of each pair of sensors.

A wind instrument such as a harmonica has a mouthpiece with one or more air channels, an electric power source, and a means for generating an electrical output signal from strain gages exposed to airflow in the channels. First and second strain gages having variable flow-induced resistance are bonded to a flexible substrate and suspended within an air channel, which includes a divider shelf for directing a first airflow to the first strain gage and a second airflow to the second strain gage. Complimentary strain gages are mounted to an opposite side of the substrate for inverse flexure to enable temperature correction for the first and second strain gages. When a user forces air through a channel in a direction biased to one side of the divider shelf a difference signal is generated by the first and second strain gages and detected by comparing their outputs. The difference signal can be used to adjust a variable control signal in applications such as volume control, dimming lights, or bending notes generated by the harmonica.

A system and method for the automatic, procedural generation of musical content in relation to biometric data. The systems and methods use a user's device, such as a cell phone to capture image data of a body part, and derive a biometric signal from the image data. The biometric signal includes biometric parameters, which are used by a music generation engine to generate music. The music generation can also be based on user-specific data and quality data related to the biometric detection process.

The present disclosure is hands-free sound modulation apparatus. The hands-free sound modulation apparatus includes one more monophonic and polyphonic sound modulation assemblies for music creation, gaming, medical rehabilitation, language training, and speech enhancement. The hands-free sound modulation apparatus can be paired with a smartphone device, musical instrument, and a network of hands-free sound modulation apparatuses.

A displacement amount detecting apparatus is provided and includes: transmission member, transmitting a displacement on one end side thereof to a displacement on the other end side thereof; a sensor, disposed to face the other end side of the transmission member, and configured to output a value according to a distance between the sensor and the other end side of the transmission member; a calculation device, calculating a value for indicating the distance based on the value output by the sensor and a reference value; and a correction device, correcting the reference value. When the one end side is displaced in a first direction, the other end side is displaced in a second direction opposite to the first direction and away from the sensor. The correction device is configured to correct the reference value based on the value for indicating the distance calculated by the calculation device.
