\subsubsection{Dynamic scene}
\label{subsubsec:dynamic_scene}
+ When using the \gls{ssr} in a more artistic context, such as musical
+ scores, or in experiment environments dealing with moving sources, this
+ requires a dynamic scene.\ sWONDER (see~\ref{subsec:swonder}) has a
+ scoreplayer application, that can be synced with \gls{midi}, which is
+ used to record and play back scores (i.e.\ recorded source properties)
+ from unvalidated \gls{xml} files. WFSCollider has a fully integrated
+ timeline, that can be used to place multiple (even concurrent) events,
+ save and play them \citep[p. 10]{manual:wfscollider}.\\

+ \label{lst:asdf.xsd-score}
+ \end{listing}\\
+
+ Unfortunately the \gls{asdf} was never properly extended for these
+ purposes (see Listing~\ref{lst:asdf.xsd-score}), which is why the
+ \gls{ssr} is not able to deal with dynamic scenes in a comparable
+ fashion yet.\\
+ Unlike sWONDER, the \gls{ssr} uses schema validated \gls{xml} only,
+ whereas 3Dj and WFSCollider use a unique format or even
+ \gls{supercollider} code as score files.\\
+ Schema validated input is less error-prone and should generally be
+ preferred over single-purpose or self-conceived formats. It would
+ therefore be a good step to consolidate the \gls{asdf} schema part
+ responsible for dynamic elements, while keeping in mind the overall
+ message throughput as discussed
+ in~\ref{subsubsec:interpolation_of_moving_sources} and thus enable the
+ \gls{ssr} to deal with dynamic scenes efficiently.\\
+ Additionally, the \gls{gui} efforts made for WFSCollider could be
+ combined with a \gls{ssr} backend, as it lacks a tool for creation and
+ controlling of dynamic content.
