Detailed Description

Controller Parameter Info.

A parameter info describes a parameter of the controller. The id must always be the same for a parameter as this uniquely identifies the parameter.

Member Enumeration Documentation

Enumerator
kNoFlags 

no flags wanted

kCanAutomate 

parameter can be automated

kIsReadOnly 

parameter cannot be changed from outside the plug-in (implies that kCanAutomate is NOT set)

kIsWrapAround 

attempts to set the parameter value out of the limits will result in a wrap around [SDK 3.0.2]

kIsList 

parameter should be displayed as list in generic editor or automation editing [SDK 3.1.0]

kIsHidden 

parameter should be NOT displayed and cannot be changed from outside the plug-in (implies that kCanAutomate is NOT set and kIsReadOnly is set) [SDK 3.7.0]

kIsProgramChange 

parameter is a program change (unitId gives info about associated unit

  • see vst3ProgramLists)
kIsBypass 

special bypass parameter (only one allowed): plug-in can handle bypass (highly recommended to export a bypass parameter for effect plug-in)
