Ardour5.12 intermediate Bus routing multichannel

I am having a problem routing the tracks of a multichannel intermediate bus to the speakers.
This is explained in this document with the appropriate screenshots

sorry, the right address is http://egridsys.org/ardour-busA.pdf

You’ll need to bypass the panner on the multi-channel bus (right-click on the panner for a context menu). By default, Ardour adds a VBAP panner to buses and track with more than two output channels, which is not what you want in this case.

ok thanks. I’m looking at that.

Thanks. It’s perfect,. But why does CBAP redistribute routing? (To understand!)

Sorry, VBAP.

There’s a little more info here: http://manual.ardour.org/mixing/panning/vbap_panner/, and much more detail at: http://legacy.spa.aalto.fi/research/cat/vbap/.
