Abstract
A data modifying apparatus having: a memory that stores modification data for modifying data; a detecting unit for detecting each data group from performance data, the data group being unable to be reproduced at the same time from the viewpoint of music; and a modifying unit for modifying the data group detected by the detecting unit to divide the data group into a plurality of sub-data groups capable of being reproduced at the same time from the viewpoint of music, by using the modification data.
Claims13
A data modifying apparatus comprising:
- a memory that stores modification data for modifying data;
- a judging device that judges whether a tone property of performance data is a specific tone property;
- a detector that detects, from performance data, a data group that simultaneously reproduces a plurality of musical tones when said judging device judges the tone property of performance data is the specific tone property;
- and
- a modifying device that modifies at least a part of the data group detected by said detector to modify at least a part of reproduction timings of the simultaneously reproduced plurality of musical tones by using the modification data.
A data modifying apparatus comprising:
- a judging device that judges whether a tone property of performance data is a specific tone property;
- a detector that detects, from the performance data, a portion of performance data that simultaneously reproduces a plurality of musical tones when said judging device judges the tone property of performance data is the specific tone property;
- and
- a modifying device that modifies at least a part of the portion of the performance data detected by said detector to modify at least a part of reproduction timings of the simultaneously reproduced plurality of musical tones.
A data modifying method comprising the steps of:
- (a) inputting modification data for modifying data;
- (b) judging whether a tone property of performance data is a specific tone property;
- (c) detecting, from performance data, a data group that simultaneously reproduces a plurality of musical tones when said judging step (b) judges the tone property of performance data is the specific tone property;
- and
- (d) modifying at least a part of the data group detected at said detecting step (c) to modify at least a part of reproduction timings of the simultaneously reproduced plurality of musical tones by using the modification data.
A data modifying method comprising the steps of:
- (a) judging whether a tone property of performance data is a specific tone property;
- (b) detecting, from the performance data, a portion of performance data that simultaneously reproduces a plurality of musical tones when said judging device judges the tone property of performance data is the specific tone property;
- and
- (c) modifying at least a part of the portion of the performance data detected at said detecting step (b) to modify at least a part of reproduction timings of the simultaneously reproduced plurality of musical tones.
A computer readable storage medium storing a program and modification data for modifying data, the program comprising the steps of:
- (a) judging whether a tone property of performance data is a specific tone property;
- (b) detecting, from performance data, a data group that simultaneously reproduces a plurality of musical tones when said judging step (a) judges the tone property of performance data is the specific tone property;
- and
- (c) modifying at least a part of the data group detected at said detecting step (b) to modify at least a part of reproduction timings of the simultaneously reproduced plurality of musical tones by using the modification data.
