LV2\protect\footnote{Optional Feature - OS dependent} is an open standard for audio plugins using a simple interface with extensions which add functionality to support audio software. These plugins were written by external developers and provide additional audio effects to \CGG{} audio without having to change \CGG{} every time. Because the LV2 plugins are separate from \CGG{} Infinity, if one fails or does not perform as expected, \CGG{} should stay running and you will have to contact the programmers responsible for that plugin for a fix.
-Typically, a user OS has specialized package groups installed. It is difficult to create one build of \CGG{} to accommodate all potential LV2 plugins. Specifically for the \textit{Calf-Studio LV2 plugins}, you should install the \textit{Calf Plugins} package. The user’s computer must have \textit{gtk-2-runtime} installed, which seems to be automatically done already for most distros. For users doing their own builds, you can build \CGG{} without LV2 support by including \texttt{-{}-without-lv2} in the configure step. The default build is \texttt{-{}-with-lv2=yes} and requires that \textit{GTK-2-devel} must be installed or the build will fail and notify you. In addition for some newer distros, you will need to install

LV2 plugins have their own category in the \textit{Audio Plugins Visibility} as lv2. There is a simple text interface which is available via the usual \textit{Show controls} button when the plugin is attached to the audio track. This window has a Reset button to get back to the default settings. To change a value of one of the parameters, highlight that parameter and type in the new value in the topmost text box and then hit Apply to take effect -- the reason for requiring hitting apply is so that the audio is not moving all over the place while you are still typing a value. More easily, you can just move the \textit{pot dial} or the \textit{slider} bar which take effect automatically.
\item[Alpha determines radius] use alpha to define the amount of blur to apply. (radius=gray value of alpha)
\item[Blur alpha, red, green, blue] specifies which color channels is to be blurred.

+If you are getting confusing results with old projects it may be a
+result of the discontinued parameter \textit{alpha determines radius}.
+For compatibility reasons and for possible future development it
+has been left in the code but hidden in the plugin's GUI.
+The parameter for \textit{alpha determines radius} is
+\texttt{A\_KEY}, which can be 0 or 1. When you press the
+\texttt{Reset} button in the Blur plugin window \texttt{A\_KEY=0}.
+
+Old projects may have saved that parameter (A\_KEY) to 1 instead
+of 0 and that may present a problem so you should do one of
+the following workarounds to change it to 0. Then be sure to save
+your project with these changes applied.
+\begin{enumerate}
+ \item Click on the \textit{Reset} button in the dialogue/controls popup box and re-enter any of your other parameter desired values.
+ \item OR in the \CGG{} program, open the project. Click on the cog icon
+(\textit{Preset edit}) of the Blur effect bar and the \textit{Keyframe
+parameters} window is open. There, you can see the A\_KEY parameter
+and change it: select the \texttt{A\_KEY} parameter and in the
+\texttt{Edit value} box, change it from 1 to 0, then press the \texttt{OK}
+button.

-When using the X11 graphics driver and RGBA-FLOAT color model, this plugin allows for greater than (0 - 1.0f) values. This does not work when using X11-OpenGL because it is an 8-bit limited driver. Both the Color wheels and the Saturation and Value sliders will make it possible to work with HDR video.

This does not work when using X11-OpenGL because it is an 8-bit limited driver. HDR values will only work for the color wheel, while the Value and Saturation sliders are always clipped to 1.0.
