NoteExpressionTypeInfo Struct Reference

NoteExpressionTypeInfo is the structure describing a note expression supported by the plug-in. More...

`#include <ivstnoteexpression.h>`

## Public Types
enum | NoteExpressionTypeFlags { kIsBipolar = 1 << 0, kIsOneShot = 1 << 1, kIsAbsolute = 1 << 2, kAssociatedParameterIDValid = 1 << 3 }

## Public Attributes
NoteExpressionTypeID | typeId
| unique identifier of this note Expression type
String128 | title
| note Expression type title (e.g. "Volume")
String128 | shortTitle
| note Expression type short title (e.g. "Vol")
String128 | units
| note Expression type unit (e.g. "dB")
int32 | unitId
| id of unit this NoteExpression belongs to (see vst3Units), in order to sort the note expression, it is possible to use unitId like for parameters. -1 means no unit used.
NoteExpressionValueDescription | valueDesc
| value description see NoteExpressionValueDescription
ParamID | associatedParameterId
| optional associated parameter ID (for mapping from note expression to global (using the parameter automation for example) and back). Only used when kAssociatedParameterIDValid is set in flags.
int32 | flags
| NoteExpressionTypeFlags (see below)

## Detailed Description

## Member Enumeration Documentation

enum NoteExpressionTypeFlags

Enumerator
kIsBipolar | event is bipolar (centered), otherwise unipolar
kIsOneShot | event occurs only one time for its associated note (at begin of the noteOn)
kIsAbsolute | This note expression will apply an absolute change to the sound (not relative (offset))
kAssociatedParameterIDValid | indicates that the associatedParameterID is valid and could be used
