An apparatus, system, and method for an electronic handheld musical instrument that generates electronic signals for processing by a processor-based module to generate musical sounds adapted to replicate non-electronic traditional hand percussion and other handheld instruments, is provided. A piezoelectric-based trigger is secured in an enclosed volume or enclosure formed in the electronic handheld musical instrument. When manipulated by a musician in a normal fashion, freely moving beads float or travel within the enclosure of the electronic handheld musical instrument and strike against a sensitive face of the piezoelectric transducer device to create a desired sound effect.

A system and method for interfacing and controlling multiple musical instrument effects modules on a common platform. The system includes: a system processor; a backplane coupled with the system processor; a plurality of musical instrument effects modules removably inserted into the backplane, each of the plurality of musical instrument effects modules including an audio input signal interface and an audio output signal interface, at least one of the musical instrument effects modules including a programmable potentiometer and/or programmable switch to modify an audio output signal; and a user interface configured to enable a user to apply a desired setting on the programmable potentiometer of the musical instrument effects modules via the system processor and the backplane.

An electronic device includes at least one processor configured to perform: receiving a selection operation from a user that selects one of a plurality of data types for a first data, the first data having a hierarchical structure, the plurality of data types being different from each other at least in terms of a way the first data is associated with a second data that is described at a different level in the hierarchical structure; and adapting the first data in accordance with the data type selected by the selection operation, and causing the adapted first data to be saved in a memory.

A waveform data structure includes a plurality of types of frames having different data sizes. Each of the plurality of types of frames includes an auxiliary information area and a data area. The auxiliary information area includes an area for storing common effective-bit length data for a section of waveform samples, and an area for storing an identifier for identifying one of the plurality of types of frames. The data area is an area for storing extracted waveform samples which are extracted from the waveform samples based on the common effective-bit length. The number of the extracted waveform samples is determined based on the common effective-bit length.

An electronic musical instrument includes a performance operating element, a second operating element configured to add an acoustic effect or change setting information including a tone, a storage unit including a first storage area that stores first performance data corresponding to an operation on the performance operating element and second performance data corresponding to an operation on the second operating element, and a second storage area that stores the second performance data, and at least one processor. The at least one processor stores, in a case where the second performance data stored in the first storage area is overwritten in a recording state, the overwritten second performance data in the second storage area, and instructs to generate a musical sound based on the first performance data stored in the first storage area and the second performance data stored in the second storage area in a reproduction state.

This electronic musical instrument main body device comprises an information acquisition unit and a port assignment unit. The information acquisition unit acquires, from a playing operation device connected to one connection terminal, information related to the playing operation device. The port assignment unit assigns, to the playing operation device, a virtual input port of a type corresponding to the information related to the playing operation device and acquired by the information acquisition unit.

An information processing apparatus includes: a memory; and at least one processor. The at least one processor is configured to, as music progresses in accordance with music data, sequentially write or overwrite each of a plurality pieces of chord data included in the music data to the memory, the chord data being a performing data played by a user, detect a user operation on manipulation elements by a user, and process to sound one or more chord component notes corresponding to the piece of chord data stored in the memory at a timing of detecting the user operation, the one or more chord component notes being in number according to the number of user operations of the manipulation elements, to which the user operations are being detected.

When an electronic musical instrument is attached to an external input/output device 13 of the sound source device 1, model information and a firmware version are received from the target electronic musical instrument, and the received version is compared with an incompatible version in a firmware table 11b. When the acquired version is an incompatible version or below, update data of the target electronic musical instrument in the firmware table 11b is acquired and transmitted to the target electronic musical instrument together with an instruction to update using the update data.
