A piano system is provided. A system including a keyboard including a plurality of keys; a plurality of sensors connected to the plurality of keys; a screen; at least one processor, and a non-transitory computer readable medium comprising instructions, the instructions, when executed by the at least one processor, causing the system to effectuate a method comprising: dividing the plurality of sensors into a first group and a second group; receiving a first sensor signal from the first group and a second sensor signal from the second group; generating a first parameter for the first group and a second parameter for the second group; generating a first sound control signal for the first group and a second sound control signal for the second group; generating visual information related to the first and the second sensor signal; and displaying the visual information on the screen.

The disclosure provides a sound emitting device includes a housing in which a corner is formed by an inner surface of a first outer wall part and an inner surface of a second outer wall part; a speaker device which includes a sound emitting part that emits a sound toward a main opening formed to penetrate through the first outer wall part and is arranged inside the housing; and a guide that is arranged between the second outer wall part and the speaker device. An auxiliary opening is provided to penetrate through the second outer wall part, and at least a part of multiple auxiliary openings is located at the same position as the sound emitting part in a length direction of the corner, and the guide includes a bottom part that projects from one of the speaker device and the second outer wall part toward the other thereof.

An electronic musical instrument includes a performance operator and at least one processor. In accordance with pitch data associated with the performance operator operated by a user, the at least one processor digitally synthesizes and outputs inferential musical sound data including inferential performance technique of a player. The inferential performance technique of the player is based on acoustic feature data output by a trained acoustic model obtained by performing machine learning on: a training score data set including training pitch data; and a training performance data set obtained by the player playing a musical instrument and is not played in the user operation of the performance operator.

The present invention aims to change contents of an automatic accompaniment in accordance with a pitch range of a key that a user plays. The electronic musical instrument includes operated keys and a processor. The processor acquires the number of operated keys for each pitch range in accordance with the operation of the keyboard and instructs to switch an automatic accompaniment pattern accompaniment sounds to be emitted in accordance with the acquired number of operated keys for each pitch range.

A system and method for operating and performing a remotely networked virtual musical instrument. A client transmits musical control data to a remote server over the network, encompassing a digital music engine and digitally sampled virtual musical instruments. In return, the client consumes, synchronizes, and mixes the combined server playback stream from the network of the fully expressive and interactive musical performance with zero audible latency.

An improved musical instrument is disclosed. The musical instrument includes at least one key assembly and at least two sets of sensors. The sensors sense one or more attributes pertaining to a force exerted on the at least one key assembly. A control unit is provided to determine amount of force sensed by sensors based on the sensed one or more attributes, and to determine location, at which the force on the at least one key assembly is exerted based on the determined amount of force sensed by the sensors. The control unit is configured to generated signals based on the determined amount of force sensed by the sensors, and the determined location. The generated signals are associated with one or more acoustic parameters.

Different aspects of the invention implement a sensor module that can be configured as a keyboard module or as a pedal module, allowing to connect a plurality of keyboard and pedal modules to assemble a configuration to the user's liking, such as, for example, the usual configuration of an 87-key piano together with two pedals. The sensor module transmits information about detected key or pedal strokes to a computer application for playback, either aural or visual. At the same time, the sensor module allows, both in the keyboard module and pedal module configuration, to transmit the feeling of playing a real piano.

A sound signal generation method includes receiving a pitch and an intensity, and generating a sound signal corresponding to the pitch such that a size of a sound image of the sound signal is adjusted in accordance with the intensity.

A children's toy with touch interactivity. The children's toy generally includes a user input panel and one or more touch sensors. The user input panel may be formed from a natural organic material such as wood. The toy can be shaped and ornamented to resemble a toy tablet with buttons or icons incorporating images of one or more animals and configured to play animal sounds or information about the animals in response to user input applied to the user input panel and sensed by the touch sensors.

A keyboard apparatus according to an embodiment includes a keyboard and a mutual capacitance proximity sensor. The keyboard includes a first key and a second key arranged in an array direction with respect to the first key. The proximity sensor includes a first electrode having a portion extending from at least a first area below the first key to a second area below the second key, a second electrode arranged in the first area, and a third electrode arranged in the second area. The proximity sensor is a mutual capacitance type sensor and is configured to use a change in capacitance between the first electrode and the second electrode and a change in capacitance between the first electrode and the third electrode.
