An electronic musical instrument is configured to: (a) acquire input data that includes habit data indicative of a playing habit of a user in playing a musical instrument; (b) generate correction data by inputting the acquired input data into at least one trained model that learns a relationship between training input data and training correction data; and (c) correct, using the generated correction data, at least one first intensity characteristic representative of a relationship between: (i) a playing intensity in playing the musical instrument by the user; and (ii) a sound intensity of a musical sound output in response to playing of the musical instrument.

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.

The present technology relates to a signal processing device, a signal processing method, and a program that enable intuitive operation of sound.

The signal processing device includes an acquisition unit that acquires a sensing value indicating a motion of a predetermined portion of a body of a user or motion of an instrument, and a control unit that performs non-linear acoustic processing on an acoustic signal according to the sensing value. The present technology can be applied to an acoustic reproduction system.

A sound production control apparatus has a position detector that detects, in accordance with a playing operation of a musical instrument, a position of a key displaceable within a movement range from a start position to an end position. The movement range includes a sounding range including a sounding position and a setting range that is closer to the start position than the sounding range. The apparatus causes a played sound associated with the key to be produced upon the detected position of the key reaching the sounding position, while controlling a characteristic of the played sound depending on a displacement characteristic of the key within the setting range before the key is positioned in the sounding range.

Techniques are disclosed relating to automatically generating new music content based on image representations of audio files. A music generation system includes a music generation subsystem and a music classification subsystem. The music generation subsystem may generate output music content according to music parameters that define policy for generating music. The classification subsystem may be used to classify whether music is generated by the music generation subsystem or is professionally produced music content. The music generation subsystem may implement an algorithm that is reinforced by prediction output from the music classification subsystem. Reinforcement may include tuning the music parameters to generate more human-like music content.

A musical performance correction method executable by a computer, the musical performance correction method includes: estimating a playing position in a musical composition by analyzing musical performance data indicating a played pitch played by a user; and correcting the played pitch indicated by the musical performance data to a reference pitch, from among a plurality of reference pitches corresponding to the playing position in the musical composition, in a case where a difference between the played pitch and the reference pitch is less than a predetermined value.
