When we're working on a production and using more than two inputs - we use an SDI audio embedder to capture four channels, its hard to see what all channels are doing.
I get around this by creating an input which is a Vmix Audio Bus so I can see what the levels are on the multiview.

But would be great if we could have a dedicated input type or way to display clearly what levels are on all busses on the multiview. not just on inputs, which is limited to stereo only.
I regularly shoot myself solo and have (in the past) recorded clips without realising that audio was not routed because there is no clear metering on the multiview. Ihave the Multiview at the back of the studio where I can see it on a large monitor.
