Music Sample Description

QuickTime Movie File Format Specification, May 1996

Music Sample Description

The music sample description uses the standard sample description header, as described in "Sample Table Atoms" .

The data format field in the sample description is always set to 'musi' . The music media handler adds an additional 32-bit integer field to the sample description containing flags. Currently no flags are defined, and this field should be set to 0.

Following the Flags field, there may be appended data in the QuickTime music format. This data consists of part-to-instrument mappings in the form of general events containing note requests. One note request event should be present for each part that will be used in the sample data.
