Music production apparatus and method of producing music by combining plural music elements

A music production method adapted for playback of music by combining music data for a plurality of melody elements stored in a melody data storage, comprising:

• determining, at a predetermined point of time, whether a melody element should be allocated to a track where no melody elements are allocated;
• selecting, when it is determined that a melody element should be allocated to the track, which is among a plurality of tracks, a melody element that should be allocated to the track by referring to a condition for combining melody elements stored in a condition storage, which stores the condition for combining melody elements and a condition related to an attribute applicable when playing the melody element;
• determining an attribute applicable when playing the selected melody element, by referring to the condition storage;
• and reading music data for the selected melody element from the melody data storage, applying the attribute determined by the determining, and producing a sound signal that should be output to a speaker, using the music data for the melody element allocated to the track.

A program product stored on a non-transitory computer readable medium adapted for playback of music by combining music data for a plurality of melody elements stored in a melody data storage, comprising:

• a module that determines, at a predetermined point of time, whether a melody element should be allocated to a track where no melody elements are allocated;
• a module that selects, when it is determined that a melody element should be allocated to the track, which is among a plurality of tracks, a melody element that should be allocated to the track by referring to the condition for combining melody elements stored in the condition storage, which stores the condition for combining melody elements and a condition related to an attribute applicable when playing the melody element;
• a module that determines an attribute applicable when playing the selected melody element, by referring to the condition storage;
• and a module that reads music data for the selected melody element from the melody data storage, applies the attribute determined by the module for determining an attribute, and producing a sound signal that should be output to a speaker, using the music data for the melody element allocated to the track.

A program product stored on a non-transitory computer readable medium comprising:

• a module that reads, from a parameter storage storing coordinate data for an object located in a three-dimensional space and a plurality of types of sound data for an object group, the coordinate data or the sound data;
• a module that changes a viewing position in the three-dimensional space;
• a module that produces an image of the three-dimensional space as viewed from the viewing position in a predetermined viewing direction;
• a module that sets up an object count determination range in the vicinity of the viewing position, counts the number of objects located in the object count determination range by referring to the parameter storage, determines, from among the plurality of types of sound data, sound data applicable to the object group, according to the number of objects, reads the sound data thus determined from the parameter storage, and produces sound at the viewing position in the three-dimensional space.

A game device comprising:

• a parameter storage operative to store coordinate data for an object located in a three-dimensional space and a plurality of types of sound data for an object group;
• a movement controller operative to change a viewing position in the three-dimensional space;
• an image production unit operative to produce an image of the three-dimensional space as viewed from the viewing position in a predetermined viewing direction;
• and a sound production unit operative to set up an object count determination range in the vicinity of the viewing position, count the number of objects located in the object count determination range by referring to the parameter storage, determine, from among the plurality of types of sound data, sound data applicable to the object group, according to the number of objects, read the sound data thus determined from the parameter storage, and produce sound at the viewing position in the three-dimensional space.

A game control method comprising:

• reading, from a parameter storage storing coordinate data for an object located in a three-dimensional space and a plurality of types of sound data for an object group, the coordinate data or the sound data;
• changing a viewing position in the three-dimensional space;
• producing an image of the three-dimensional space as viewed from the viewing position in a predetermined viewing direction;
• setting up an object count determination range in the vicinity of the viewing position, counting the number of objects located in the object count determination range by referring to the parameter storage, determining, from among the plurality of types of sound data, sound data applicable to the object group, according to the number of objects, reading the sound data thus determined from the parameter storage, and producing sound at the viewing position in the three-dimensional space.
