Multi-Object Busses
You can make stereo and multi-channel busses available as multi-object busses.
Normally, objects are meant to be mono, but you can also create stereo or multi-channel
busses and make them available as multi-object busses. This allows you to tilt and rotate
pre-panned multi-channel signals in the Dolby Atmos surround field, for example, a 5.0
channel background mix.
NOTE
•
Due to the close distance between side and top speakers in a Dolby Atmos system,
tilting of multi-channel signals allows for a signal panning that may not always be
perfectly reproduced.
•
In Object Mode, there is no LFE channel. If you want to use a surround bus with an LFE
channel, for example 5.1, as multi-object bus, it is recommended to downmix the LFE
channel first.
EXAMPLE
1.
In the VST Connections window, create a 5.0 output bus and connect it to audio
streams that are defined as objects in the Object Mapping dialog.
2.
In the VST MultiPanner, click Select Object Bus and select the 5.0 output bus.
The panner now sends 5 objects to the Dolby RMU.

Object Mixing with VST MultiPanner
If you use a Dolby RMU, the VST MultiPanner offers two modes for creating both a channel-
based bed mix and an object-based mix for Dolby Atmos.
In Bed Mode, the panner offers the same functions as if it is used without RMU and allows
you to create the audio bed of your Dolby Atmos mix. In Object Mode, the panner allows
panning for audio objects in your Dolby Atmos mix. The Bed Mode and Object Mode buttons
allow you to switch between both modes. The following applies:
•
In Object Mode, 3D panning functions are always provided, regardless of the audio
routing.
•
If the VST MultiPanner is used as an insert plug-in, Object Mode is not available.
•
If the switch between Bed Mode and Object Mode is automated, the bypass of send 8 is
automated accordingly, using its own automation track.
•
If the switch between Bed Mode and Object Mode is automated and the parameter
settings differ between both modes, existing automation of a parameter that is not
available due to the mode change remains.
