3.3 Plugins<br />
To automate movements of sources with a multi-track sequencer, three LADSPA plugins were created<br />
to do so. One to send out OSC movement commands for one source, and one to send out OSC<br />
movement commands for a group of two sources and one for a group of 4 sources, of which a center<br />
point can be moved, and the scale and rotation of the cloud of points can be varied.<br />
3.4 User interface and score player/recorder<br />
A graphical user interface is in development, which shows a 3D view (in OpenGL) on the room,<br />
and the virtual sound sources, which can be moved around through the space. It is also possible to<br />
view a t<strong>im</strong>eline of the source movements in 3D view. Additionally, a score player and recorder is in<br />
development that can synchronize using Midi T<strong>im</strong>e Code (MTC) with common audio sequencers<br />
(e.g. Ardour or ProTools).<br />
