Surround Routing
The processing format of VST MultiPanner depends on the channel routing. You can use the Routing and the Direct Routing racks in the MixConsole to route audio-related tracks to output busses or group channels with a surround configuration.
For example, if a mono source channel is routed to a 5.1 bus, the panner works in 5.1 mode. For channel-based 3D mixing, route the source channel to an output bus that provides top channel speakers.
