DLS Structures
This section contains reference information for structures used with Downloadable Sounds. Most applications do not need to use these structures, because DirectMusic handles the details of loading DLS collections and downloading instruments to the synthesizer. They are of interest chiefly for applications that edit DLS.
For an overview of using DLS data, see Low-Level DLS.
For more information on DLS data formats, see the specification from the MIDI Manufacturers Association.
The following structures are included in this section.
| Structure | Description |
| DMUS_ARTICPARAMS | Describes parameters for a DLS articulation chunk. |
| DMUS_ARTICULATION | Describes a DLS level 1 articulation chunk. |
| DMUS_ARTICULATION2 | Describes a DLS level 1 or level 2 articulation chunk. |
| DMUS_COPYRIGHT | Describes an optional copyright chunk in DLS data |
| DMUS_DOWNLOADINFO | Used as a header for DLS data to be downloaded to a port. |
| DMUS_EXTENSIONCHUNK | Describes a DLS extension chunk. |
