Disclosed herein are a number of example embodiments for an improved audio sample playback unit. For example, multi-dimensional mapping of triggers to audio samples is disclosed. Also disclosed is low latency retrieval and playback of audio samples via pre-loading of sample heads into high speed memory. Furthermore, disclosed herein is a multi-threaded control operation for generating audio frames in response to trigger inputs, as well as the use of multiple pipes from which audio data can be generated. Further still, an example embodiment provides for multi-level control of audio properties, including voice-specific controls, pipe-specific controls, and global controls.

A sound processing device includes: a combining processor that combines a performance sound and a source sound, based on operation information corresponding to a performance operation on an instrument. The performance sound is obtained by picking up a sound generated by the performance operation on the instrument. The source sound is obtained from a sound source.

An apparatus, system, and method for a magnetically and releasably attachable trigger for an instrument is provided. Additionally, the trigger provides for an increased sensitivity of sound by being in direct physical contact with the surface on which it is attached.

Disclosed is a learning model generation method executed by a computer, including: striking a percussion instrument with a striking member to emit a musical sound; and conducting machine learning upon receiving an input of the musical sound emitted from the percussion instrument, and generating, based on the machine learning, a learning model for outputting numerical values for setting musical performance parameters for an automatic musical performance of the percussion instrument that is struck when the striking member is driven.

A device is provided for capturing vibrations produced by an object such as a musical instrument such as a cymbal of a drum kit. The device comprises a detectable element, such as a ferromagnetic element, such as a metal shim and a sensor spaced apart from and located relative to the musical instrument. The detectable element is located between the sensor and the musical instrument. When the musical instrument vibrates, the sensor remains stationary and the detectable element is vibrated relative to the sensor by the musical instrument.

An apparatus, system, and method for a magnetically and releasably attachable trigger for an instrument is provided. Additionally, the trigger provides for an increased sensitivity of sound by being in direct physical contact with the surface on which it is attached.

An electronic musical instrument that is easy to use is provided. The electronic musical instrument includes a packing box (2) formed into a box shape capable of accommodating a converter (4) and an output device (5). The packing box (2) has an opening portion (21a) formed in a side surface, and thus it is possible to use the packing box (2) as a percussion instrument simulating a Cajon taking the opening portion (21) a as a sound hole. That is, an electronic musical instrument (1) is used employing the packing box (2) that simulates a Cajon, and thus labor for preparing a musical instrument is saved. Thus, the electronic musical instrument (1) is easy to use.

To provide a change of sound in response to a player's operation that is close to the change of sound of real hi-hat cymbals. A hi-hat cymbal sound generation apparatus according to the present invention includes an input part, a recording part, a trigger part and a sound volume control part. The input part acquires state information and vibration information. The recording part records data on a foot close sound, data on a foot open sound, and data on a hit sound in each state indicated by the state information. The trigger part checks whether the vibration indicated by the vibration information falls within a predetermined range in which a sound generation procedure is to be started, and starts sound generation procedures for at least all the hit sounds when the trigger part determines that the vibration falls within the range in which a sound generation procedure is to be started.

A hi-hat cymbal sound generation apparatus according to the present invention includes an input part, a recording part, a trigger part and a sound volume control part. The input part acquires distance information on a distance between a top pad and a bottom pad, state information and vibration information on a vibration of the top pad. The input part acquires the state information by determining the state information based on a corrected distance, which is obtained by adding a distance correction value, which corresponds to a magnitude of the vibration indicated by the vibration information, to the distance indicated by the distance information. The recording part records data on a hit sound in each state indicated by the state information. The trigger part checks whether the vibration indicated by the vibration information falls within a predetermined range in which a sound generation procedure is to be started.

A sound processing device includes: a combining processor that combines a performance sound and a source sound, based on operation information corresponding to a performance operation on an instrument. The performance sound is obtained by picking up a sound generated by the performance operation on the instrument. The source sound is obtained from a sound source.
