This is a multichannel variant of the O3A Panner LS. Eight channel strips are provided, each with an additional gain control and mute/solo buttons.
The plugin is available in the O3A Manipulators plugin library.
When this option is available, a 'View' button appears at the top right of the plugin's user interface.
When this is pressed, the plugin is connected to the View or ViewVR application and is displayed there.

The current source directions are shown using colour-coded crosses and labels, similar to the display used by O3A Panner - Eight Channel.
Point at one and hold the left mouse button to select it. Then, drag to set its direction.
The current 3D locations are shown as small scaled spheres, within a scaled cube, which should be in reach of the VR controllers. The unscaled locations, where the audio is actually presented from, are also shown.
Grab one of the scaled locations with a VR controller and drag to move it. The unscaled sphere will move to match.
This rolloff determines the rule that is used to reduce the source's level as the source moves away. A value of 1 is closest to how this occurs in reality. Reducing the value reduces the effect of the level drop and increasing the value exaggerates it. A value of 0 means that the level stays constant.
Mathematically, the gain applied is determined by the inverse square law, but raised to a power given by this control.
This controls a simple low-pass filter that reduces high frequency content as the source moves away. This happens in reality due to air absorption. A value of 0.1 is close to reality at typical pressure, temperature and humidity, and changing this value reduces or increases the effect. A value of 0 means that no filtering occurs.
The value used with this control is the number of additional decibels lost at 10kHz for each metre of distance, on top of the main gain rolloff.
The coordinates determine where each sound is in space. Units are nominally metres.
Source size can be used to give a source a volume. When the source is close, this changes the spatial response of the source (you will see it looks bigger in the O3A Visualiser). This effect continues when the listener travels inside the source.
When the listener is inside the source, there is a substantial omnidirectional component to the soundfield generated here. You may wish to make this more diffuse, for instance by using the O3A Diffuser plugin.
The edge setting further determines the shape of a source with size. Increasing the edge setting introduces tapering from the edge of the source, effectively moving more of it towards its centre. This changes the spatial response of the source, particularly when it is close.
Each sound source has its own gain control, with a range from -60dB to +12dB.
Each sound source has its own mute and solo switch. These have the usual meanings and solo overrides mute.
