Detailed Description

Module Description

Constants, Types and Enum definitions that are common to both Device and Host modes for the USB MIDI Class.

Define Documentation

#define MIDI_CHANNEL

(

channel

)

((channel) - 1)

Convenience macro. MIDI channels are numbered from 1-10 (natural numbers) however the logical channel addresses are zero-indexed. This converts a natural MIDI channel number into the logical channel address.

Parameters:

[in]

channel

MIDI channel number to address.

#define MIDI_COMMAND_NOTE_OFF   0x80

MIDI command for a note off (deactivation) event.

#define MIDI_COMMAND_NOTE_ON   0x90

MIDI command for a note on (activation) event.

#define MIDI_STANDARD_VELOCITY   64

Standard key press velocity value used for all note events.

Enumeration Type Documentation

enum MIDI_JackTypes_t

Enum for the possible MIDI jack types in a MIDI device jack descriptor.

Enumerator:

MIDI_JACKTYPE_Embedded	MIDI class descriptor jack type value for an embedded (logical) MIDI input or output jack.
MIDI_JACKTYPE_External	MIDI class descriptor jack type value for an external (physical) MIDI input or output jack.
