Abstract
Measures each contain plural event data, which are memorized in an arrangement of SNG-SONG. 1024 measures (the first measure to 1023-th measure) in each music or in each track of the music are grouped into 8 measure blocks. Leading event data of 8 measure blocks each containing 128 measures are memorized in an arrangement of SNG-BAR-PTR. Element numbers of leading event data of respective 128 measures contained in each measure block are memorized in an arrangement of SNG-BAR-TBL. For example, increment or decrement of a point value of the measure block in the arrangement of SNG-BAR-TBL or the measure in the arrangement of SNG-BAR-PTR allows a fast forward reproduction and/or a fast rewind reproduction.
Claims23
An automatic performance control apparatus comprising:
- first memory for storing plural measure data each containing plural event data, each event data including time data counted from a leading position in the measure data;
- second memory for storing plural measure-data designating data which designate locations in said first memory where event data contained in the measure data are stored;
- a series of measure-data designating data which are continuously stored in said second memory being grouped into plural measure blocks, each measure block containing a group of measure-data designating data;
- third memory for storing measure-block designating data which designate locations in said second memory where the groups of measure-data designating data contained in the respective measure blocks are stored;
- and
- control means for processing the measure-block designating data stored in said third memory and the measure-data designating data stored in said second memory to control the automatic performance of event data contained in the plural measure data stored is said first memory.
A musical data storing device comprising:
- first memory for storing plural measure data each containing plural event data, each event data including time data counted from a leading position in the measure data;
- second memory for storing plural measure-data designating data which designate locations in said first memory where event data contained in the measure data are stored;
- a series of measure-data designating data which are continously stored in said second memory being grouped into plural measure blocks, each measure block containing a group of measure-data designating data;
- and
- third memory for storing measure-block designating data which designate locations in said second memory where the groups of measure-data designating data contained in the respective measure blocks are stored.
