ASPiK-GUI

Classes
class	ParamSmoother< T >
	The ParamSmoother object performs parameter smoothing on GUI control information. You can choose linear or exponential smoothing. More...
class	VSTGUI::ControlUpdateReceiver
	The ControlUpdateReceiver object is the connection mechanism between PluginParameter objects and their connected GUI control objects. It was originally designed almost identically to the example code in the VSTGUI4 SDK for the VST3 version. However, once the AU, AAX, VST3 and RAFX2 APIs were consolidated, this object changed significantly. If you are interested in creating your own version, check out the VST3 files that are included with the vstgui SDK. More...
class	VSTGUI::PluginGUI
	The PluginGUI object that maintains the entire GUI operation and has #defines to use with AAX, AU, VST3 and RAFX2 plugins. Note the multiple inheritance inolved with this very complex object. The IGUIView interface is the only non-VSTGUI4 base class. It allows for GUI resizing and manipulation, if and only if the host DAW allows and provides the mechanism for it. More...
class	PluginParameter
	The PluginParameter object stores all of the data needed for any type of plugin parameter. It is a large object, but it is not complex as it really just stores LOTS of information about plugin parameters. More...

Detailed Description

The VSTGUI::PluginGUI:

• handles all of the GUI functionality including the GUI designer
• is built using the VSTGUI4 library
• is platform independent
• does not link to any pre-compiled libraries
• encodes the entire GUI in a single XML file, including the graphics file data; this one file may be moved or copied from one project to another, allowing the whole GUI to be easily moved or reused in other projects; advanced users may define multiple GUIs in multiple XML files which may be swapped in and out
• contains API-specific code in the few places where it is absolutely needed (namely for the AU event-listener system)
• supports the VTSGUI4 Custom View and Sub-Controller paradigms to extend its functionality
• exists independently from the PluginCore and does not know, or need to know, of the PluginCore’s existence
• does not hold a pointer to the PluginCore object or share any resources with it
• NOTE: the PluginGUI object is defined within the VSTGUI namespace and is grouped with more VSTGUI objects that you may use

The PluginParameter:

• stores plugin parameters as atomic variables for thread-safe operation
• encapsulates each parameter specific to the plugin as a C++ object
• can store all types of input parameters; ints, floats, doubles, string-lists, and custom user types
• can implement audio meters, complete with meter ballistics (attack and release times) and various envelope detection schemes: peak, MS, RMS and in linear or log format
• implements optional automatic variable-binding to connect GUI parameter changes to plugin variables in a completely thread-safe manner across all APIs
• has an optional auxiliary storage system to maintain other information along with any of the plugin parameters allowing you to easily customize and extend the object
• implements optional parameter smoothing for glitch-free GUI controls with two types of smoothing available: linear and exponential
• automatically implements four types of control tapering: linear, log, anti-log, and volt/octave
• implements optional sample-accurate automation for VST3 plugins (VST3 is the only API that has a specification for sample-accurate automation)
