Classes and Structures

Structure: INSTRUMENT

Represents a single instrument within a SoundFont. The presets for this instrument are stored separately.

The available accessors are:

• INST-NAME instrument -> string
• INST-REGION instrument -> (simple-array instrument-region)

Structure: INSTRUMENT-REGION

Represents a SoundFont instrument region. Regions contain all the parameters necessary in order to synthesize a note.

The available accessors are:

• INST-REGION-SAMPLE instrument-region -> (or null sample-header)
