Electronic music apparatus capable of reproducing composite music file, and program therefor

Abstract

Composite music file is composed of a content section including a plurality of types of music content, and a header section including content type information of the plurality of types of music content. At least the content type information included in the header section is in a non-encrypted form. Once a composite music file is input, the content type information is read out from the header section of the input composite music file (S12), and one usable music software is selected, on the basis of the content type information, from among a plurality of types of music software capable of reproducing the plurality of types of music content (S16), so that the thus-selected music software is automatically started up (S18).

Description

technical field [0001] The present invention relates to an electronic music apparatus capable of efficiently reproducing music-related content contained in a composite music file having a plurality of music-related contents contained together as a single file Therein; also relates to a method for reproducing such a synthesized music file, and a computer program for reproducing the synthesized music file. Note that the term "electronic music device" is used herein to refer to every conceivable electronic device with music-related reproduction / display functions, such as electronic musical instruments, automatic performance devices, automatic reproduction devices, effectors, automatic music synthesis devices , score creation / display devices and computers with some type of music or sound reproduction software. Background technique [0002] In general, examples of music-related content (hereinafter referred to as "music content") include various data such as MIDI (Musical Instru...

AI Technical Summary

Problems solved by technology

However, since most of the music content today is provided to interested users in an encrypted form to protect the copyright of the music content, the catalog of the music content is unknown until the music content is decrypted

This synthesized music content must undergo a decryption process based on public keys and other information, which is often a cumbersome and time-consuming process

This is inconvenient due to the cumbersome decryption process required to open an encrypted composite music file, view the file's structure directory, and then identify what music content is contained in the file

[0008] In addition, if the content downloaded via the Internet or the like includes such a synthesized music file, the user cannot easily determine which application software should be used to reproduce or process the content differently, which is also very inconvenient.
