## Detailed Description

    Event

Structure representing a single Event of different types associated to a specific event (kEvent) bus.

## Member Enumeration Documentation

enum EventFlags

Event Flags - used for Event::flags.

Enumerator
kIsLive | indicates that the event is played live (directly from keyboard)
kUserReserved1 | reserved for user (for internal use)
kUserReserved2 | reserved for user (for internal use)

enum EventTypes

Event Types - used for Event::type.

Enumerator
kNoteOnEvent | is NoteOnEvent
kNoteOffEvent | is NoteOffEvent
kDataEvent | is DataEvent
kPolyPressureEvent | is PolyPressureEvent
kNoteExpressionValueEvent | is NoteExpressionValueEvent
kNoteExpressionTextEvent | is NoteExpressionTextEvent
kChordEvent | is ChordEvent
kScaleEvent | is ScaleEvent
kLegacyMIDICCOutEvent | is LegacyMIDICCOutEvent
