Often users working on media where Audio is the main focus, want all of a media's audio channels, whether stereo or 5:1 channels, to be treated as a single unit. They are more familiar with working with a DAW (Digital Audio Workstation software) and find that it takes extra work and a lot more care to have to individually manage audio tracks rather than have them automatically edited as a ganged group.
-To get this capability, there is a \textit{Gang Tracks} \index{gang tracks toggle} toggle button on the main timeline controls to switch between 3 modes of working with multiple channels so that the tracks are automatically edited as a single unit. Operations affected include edits such as cuts, moving sections, and adding plugins. Group masters are marked by the \textit{Master Track} \index{master track} toggle in the patchbays \index{patchbay}. A track gang group begins on a master track, and extends to, but not including, the next master track. The 3 \textit{Gang Tracks} modes are:

Operations affected include edits such as cuts, moving sections, and adding plugins. In addition to letting you work on the tracks of a group as one, you also get a saving of space on the timeline that makes it easier to view and edit the tracks. Group masters are marked by the \textit{Master Track} \index{master track} toggle in the patchbays \index{patchbay}. A track gang group begins on a master track, and extends to, but not including, the next master track. The 3 \textit{Gang Tracks} modes are:
\begin{enumerate}
\item \textbf{Gang None:} this is the default mode and is the traditional way Cinelerra operates. If you never toggle the "Gang Tracks" button, everything operates normally as it always has. In this mode, the button icon looks like 3 tracks with $\dots$ on the end and all tracks are visible on the timeline. See figure~\ref{fig:gang-track-01}
-\end{enumerate}
\begin{figure}[htpb]

\label{fig:gang-track-01}
\end{figure}

-\begin{enumerate}[start=2]
- \item \textbf{Gang Channels:} in this mode, all \textit{Master Tracks}
-are shown. The exception is when there is no
-Master video, no Master audio or no Master subtitle track, in which case for
-each the first track of video, audio, and subtitle will be shown. For users who
-routinely switch the track order frequently, the patchbay has the \textit{Master Track} icon to set your own preference.
-Stereo tracks, or 5:1 channels/any number of audio tracks, are drawn as 1 audio track for the purpose of making changes on that single track which are propagated to all of its other channel tracks automatically. This is the DAW-like mode. The \textit{Gang Tracks} button icon looks like 2 tracks and only the first video and first audio tracks will be shown. See figure~\ref{fig:gang-track-02}

-\begin{enumerate}[start=3]
\item \textbf{Gang Media:} this mode only shows the \textit{Master Tracks} of the media but changes are propagated to the appropriate other related tracks (even if they are not visible). The \textit{Gang Tracks} button icon looks like a single track. See figure~\ref{fig:gang-track-03}
\end{enumerate}
The current \textit{Gang Tracks} mode is saved across sessions and will be saved in your project. Although most likely users will work in the \textit{Gang None} mode, users more familiar with DAW software will tend to use the \textit{Gang Channel}s mode.
-More details are described next about master tracks. Each patchbay has a \textit{Master Track} button on the extreme right of the patchbay. These mark which tracks of the media are master tracks. The span of tracks between the gang group masters are the gang track group. The master track toggles can be disabled/enabled as the user wishes to create the desired track groups. Normal file loads will mark the first stream of each file loaded as a master, if the media is loaded with insertion strategy of\textit{ Replace current project}, \textit{Replace current project and concatenate tracks} or \textit{Append in new tracks}. Frequently, editing is done on video, audio, or audio/video groups to maintain timeline synchronization. By grouping related tracks, this procedure is much more automatic.

Previously existing projects created before the addition of ganged tracks, will have ALL tracks marked as master tracks and changing the \textit{Gang Tracks} button mode will have no effect. The user will have to properly designate which track is the master track and disabling the others in order to make use of the toggle modes.
NOTES:
\begin{itemize}
- \item When in \textit{Gang Channels} or \textit{Gang Media} mode, if the first audio track is not disarmed, but any of its connected channel tracks are, the disarm of those channels are ignored and all channels are treated as being armed. This is to be consistent with the purpose of using this mode; the purpose being that any edits to the first master track are automatically propagated to all other channels.
+ \item When in \textit{Gang Channels} or \textit{Gang Media} mode, if the first audio track is not disarmed, but any of its connected channel tracks are, the disarm of those channels are ignored and all channels are treated as being armed. This is to be consistent with the purpose of using this mode; the purpose being that any edits to the first master track are automatically propagated to all other channels. \textit{Warning}: this behavior is contrary to the default of \CGG{} whereby an unarmed track never undergoes any alteration. This exception was made to mimic the behavior of DAWs, where the various channels of an audio track are combined into a single "line", and it makes no sense to talk about armed or unarmed channels.
\item It may be better when using the \textit{Gang Channels} or \textit{Gang Media} mode to make any changes
to the first audio channel to be automatically duplicated before reverting to the \textit{Gang None} mode to make other changes. Once you start changing individual channels (that is, audio tracks) so that they are no longer coordinated in their edits/plugins, it may be more difficult to switch back to \textit{Gang Channels} mode and get the desired results since the channels may no longer be lined up.
- \item Gang modes should not be used with Multi-camera/Mixers because they have very specific
-operational capabilities which are not compatible with the way that Ganging works.
- \item Gang flags in the patchbay specifically when in \textit{Gang Channels} or \textit{Gang Media} modes will
-operate as set in the Master Track. For example, if when in \textit{Gang Channels} mode, you turn off
-“Play track” on the visible audio track, none of the associated channels (i.e. the other stereo or
-other 5 channels will play). And if in \textit{Gang Media} mode, if you turn on “Play track” for the
-Master Track, all associated video and audio tracks will play unless you turned off “Play track” for
-some of the associated audio/video slave tracks which will not play.
- \item When adding a Plugin/Effect in \textit{Gang Channels} or \textit{Gang Media} mode to the track, highlighted selected region, or In/Out pointers area via
- dragging the plugin from the Resources Window the plugin will be added on the master and all slave tracks. If using the Audio or Video pulldown, \textit{Attach Effect} option and you want
-to propagate the effect to all slave tracks, make sure that the checkbox for "Attach single standalone
-and share others" in the Dialog window is checked. However, currently when using the right mouse button (RMB) on the master track to \textit{Attach effect}, the effect will only be inserted on that track.

\label{sec:how_use_plugins}
-\textit{Realtime} effect plugins are listed in the Resources window as \textit{Audio} Effects and \textit{Video} Effects. Effect plugins are used by dragging them from the Resources window onto an audio track if it is an audio effect or video track if it is a video effect. You will see a colored bar \index{plugins!toolbar} appear beneath the track with the plugin name on it. If there is data on the destination track, the effect is applied to the entire track, unless a edit or a region of the track is selected in which case the effect is pasted into that region only. If there is no data on the track or no selected region set, the effect is not added.

If there is no data on the track or no selected region set, the effect is not added.
-Plugins are layered under the track they apply to. When dragging more than one effect onto a track, you will see the effects layering from \textit{top to bottom}, on the bottom of that track. When the track is played back, effects are processed from \textit{top to bottom}. The output of the top effect becomes the input of the bottom effect and so on. "The pipeline in Cinelerra's\protect\footnote{credit to Original Creator} plugin design is the \textit{pull} method. The rendering pipeline starts at the final output and the final steps in the rendering pipeline are reading the data from disk. Every step in the rendering chain involves requesting data from the previous step. When the rendering pipeline eventually requests data from a plugin chain, each plugin requests data from the plugin before it. This is less intuitive than the push method but is much more powerful. Realtime plugins written using the pull method can change the rate data is presented to the viewer and the direction of playback. The pull method allows plugins to take in data at a higher rate than they send it out." Side note: if you want to avoid the automatic \textit{top to bottom} application of
-plugins, you can take advantage of \textit{nested assets} to manipulate the order the plugins are applied (see
- \ref{sec:nesting_clips_and_assets}).

-Instead of dragging from the Resources window, effects may be applied to a track via a popup menu. Right click on a track and select \textit{Attach effect} \index{plugins!attch effect} from the popup. The attach effect dialog gives you more capability than just dragging and dropping. For example, the attach effect dialog lets you attach two more types of effects: \textit{shared effects} and \textit{shared tracks} which are explained in a later section. Select a plugin from the Plugins column and hit the green colored checkmark under the plugins column to attach it. The result is the same as if the effect was dragged from the Resources window.
+Instead of dragging from the Resources window, effects may be applied to a single armed track or a region via a popup menu.

-One more method to apply an effect is to use the Video or Audio pulldown \textit{Attach Effect} option. This brings up a menu which has a useful checkbox to \textit{Attach single standalone and share others} (see \ref{sec:shared_effect_tracks}). The default setting is checked on.

After attaching an effect to a track, it often needs to be configured. There are two ways to get to the configuration controls. Click on the magnifying glass \index{plugins!show controls} symbol on the right side of the effect bar -- this is the middle symbol on the bar as you can see in the picture below. Alternatively, you can right click on the effect bar to bring up the effect popup which has a \textit{Show} option. Either method causes the GUI for the effect to appear in a separate window. There will not be a popup if the plugin has no GUI.
