Member Data Documentation

hints

uint32_t Parameter::hints

Hints describing this parameter.

Parameter Hints

name

String Parameter::name

The name of this parameter.
A parameter name can contain any character, but hosts might have a hard time with non-ascii ones.
The name doesn't have to be unique within a plugin instance, but it's recommended.

shortName

String Parameter::shortName

The short name of this parameter.
Used when displaying the parameter name in a very limited space.

Note

This value is optional, the full name is used when the short one is missing.

symbol

String Parameter::symbol

The symbol of this parameter.
A parameter symbol is a short restricted name used as a machine and human readable identifier.
The first character must be one of _, a-z or A-Z and subsequent characters can be from _, a-z, A-Z and 0-9.

Note

Parameter symbols MUST be unique within a plugin instance.

unit

String Parameter::unit

The unit of this parameter.
This means something like "dB", "kHz" and "ms".
Can be left blank if a unit does not apply to this parameter.

description

String Parameter::description

An extensive description/comment about the parameter.

Note

This value is optional and only used for LV2.

ranges

ParameterRanges Parameter::ranges

Ranges of this parameter.
The ranges describe the default, minimum and maximum values.

enumValues

ParameterEnumerationValues Parameter::enumValues

Enumeration details.
Can be used to give meaning to parameter values, working as an enumeration.

designation

ParameterDesignation Parameter::designation

Designation for this parameter.

midiCC

uint8_t Parameter::midiCC

MIDI CC to use by default on this parameter.
A value of 0 or 32 (bank change) is considered invalid.
Must also be less or equal to 120.

Note

This value is only a hint! Hosts might map it automatically or completely ignore it.

groupId

uint32_t Parameter::groupId

The group id that this parameter belongs to. No group is assigned by default.

You can use a group from PredefinedPortGroups or roll your own.
When rolling your own port groups, you MUST start their group ids from 0 and they MUST be sequential.
