A method of generating a musical score file for one or more target musical instruments with a score generation component based on input audio data. The score generation component finds candidate musical notes within the input audio data using a frequency analysis to identify segments that share substantially the same audio frequency, and finds a best match for those candidate musical notes in audio data associated with target musical instruments in a sound database. A generated musical score file can be printed as sheet music or audibly played back over speakers.

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.

A musical sound generation device including a first memory having a plurality of storage areas where waveform data is read out and stored, a waveform generator which functions as a plurality of waveform generating sections each of which generates a waveform for emitting a sound by reading out waveform data from a selected storage area of the first memory; and a control processor which determines, when an instruction for sound emission is provided, a combination of a waveform generating section and a storage area to be used for the instructed sound emission, based on a status of reading waveform data from each storage area by each waveform generating section.

When transferring waveform data from a waveform region in a high-capacity flash memory to a waveform buffer in a RAM, first, whether a non-ring buffer region that can receive the waveform data can be allocated in the RAM is determined, and if so, the waveform data is transferred to the allocated non-ring buffer region. If such a non-ring buffer region cannot be allocated, then whether a ring buffer region that can receive the waveform data can be allocated in the RAM is determined, and if so, the waveform data is transferred to the ring-buffer region in a ring buffer operational manner.

A musical sound generation device including a first memory having a plurality of waveform data, a second memory which stores waveform data read out from the first memory, and a control processor which controls such that, when a sound emission instruction is provided and specified waveform data is in the second memory, the waveform data is read out by the sound source processor, or controls such that, when a sound emission instruction is provided and specified waveform data is not in the second memory, the specified waveform data is transferred from the first memory to the second memory and read out by the sound source processor, in which the control processor controls such that waveform data satisfying a set condition is not subjected to a waveform data change by the transfer and waveform data not satisfying the set condition is subjected to the waveform data change by the transfer.

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.
