VST3 multichannel

I’ve been testing armada (Fiedler audio) with Ardour and MixBus. When adding the plugin to multichannel tracks, the AU version results in a multichannel pin setting, while the VST3 version reduces the plugin to multiple stereo instances. This happens with Ardour 9.70 and MixBus 11.3. I don’t have the same behaviour in other hosts.
