The 3D display shows sound sources as spheres or ovoids. Spheres are mono sources, ovoids are stereo sources. The elongation of the ovoid displays the ‘stereo width’.

Loudspeakers are shown as boxes.

The frame grid shows the cuboid ‘V-Space’ virtual room, which provides a reverberation model.

The green arrow, pointing forward,  represents the listener.

The positions of the sources in 3D space are controlled by the ‘Input Panners’ panel, shown on the right, or by incoming Midi and OSC.

The colours of the sources can be chosen, and they can be given a name.

The ‘camera’ can be moved to give different views of the scene.

16 mono or 8 stereo sources (or any combination of mono and stereo up to a maximum of 16 audio channels) can be used. Each of the 16 ‘panners’ can be mono or stereo.

The ‘panners ‘are stacked vertically, with controlling number boxes, switches and menus for each ‘panner’ laid out in a row.

Some controls affect the spatial position of the incoming audio, and some the sonic behaviour when the source moves (Doppler shift, decrease in level when the sound becomes more distant, etc.). Others set the level of the sound source, and the amount of reverberation.

The position and settings for all sources can be stored in a memory location, along with a time for each ‘panner’ over which any change takes place. These memory locations can be recalled by Midi Program Change messages.

The size and characteristics of the ‘V-Space’ virtual room is also controlled on this panel, and stored in the memory locations along with the ‘panner’ data, so the room can change along with the position of the sound sources within it.
