       \subsubsection{Assigning in- and outputs on the fly}
         \label{subsubsec:assigning_in_and_outputs_on_the_fly}
+        The \gls{ssr}, being a \gls{jack} client, is able to add inputs for its
+        sources and outputs for its renderers according to the configuration
+        variables \mintinline{yaml}{INPUT_PREFIX} and
+        \mintinline{yaml}{OUTPUT_PREFIX}, as shown in
+        Listing~\ref{lst:ssr.conf.example}.\\
+
+        \begin{listing}[!htb]
+          \begin{mdframed}
+            \inputminted[numbers=left, firstline=44, lastline=50,
+            fontsize=\footnotesize,
+          breaklines]{yaml}{../../ssr/data/ssr.conf.example}
+          \end{mdframed}
+          \caption{data/ssr.conf.example: \gls{jack} settings in the \gls{ssr}
+          configuration file}
+          \label{lst:ssr.conf.example}
+        \end{listing}\\
+
+        The approach however is somewhat static, as it only allows setting up
+        one predefined client during startup. This can be the system's hardware
+        in- and outputs or other \gls{jack} clients. The selected input name is
+        added to the prefix to connect a \gls{ssr} source to a \gls{jack}
+        client output with that name. Following the configuration file example,
+        given a source input name of \mintinline{yaml}{1}, the \gls{ssr} would
+        connect to the \gls{jack} client port named
+        \mintinline{yaml}{alsa_pcm:capture_1}.\\
+        Dynamically reassigning source input or renderer output connections is
+        only possible by using external tools, able to handle connections of a
+        \gls{jack} session, such as QjackCtl \citep{website:qjackctl}, Patchage
+        \citep{website:patchage} or aj-snapshot \citep{website:aj-snapshot}.\\
+        Every \gls{jack} client is allowed to make connections to other clients
+        on the same server on its own. This general feature should be harnessed
+        in the case of the \gls{ssr} to allow assigning and reassigning of
+        source inputs and renderer outputs on the fly and exposing this
+        functionality to the \gls{osc} interface (i.e.\ by modifying and
+        extending the \gls{pubsub} interface).\\
+        This would make the application more dynamic and allow easier scripting
+        of scenes and reproduction setups alike. This becomes especially useful
+        in the case of listening experiments, as the experiments will not have
+        to rely on a mixture of different scripting languages anymore (e.g.\
+        see experimental setup in attachment of \citep{DmitryGrigoriev1896}).
