I have 4 channels of audio coming in over SDI.

I want to use them all as mono channels and send two of them to the Master and Two to Bus A.

Setting the Channel setting to separate mono totally breaks output on the Buses. I don't understand why. I assume this is a bug?

Is there any way to customize the Audio mixer page?

Here's what I got but I'm trying to figure out a better solution. The best thing I can think of is assigning everything to both left and right of their respective buses. Then opening the video input and opening audio settings when I need to adjust something. However this isn't great in the middle of a production, and I would very much like to see the input levels of different channels. Instead of one mono meter.

I also can't get SetVolumeChannelMixer to work with a midi controller. It is setup like Value = Channel,Volume 0-100, Value,Input

But there doesn't seem to be a way to assign a midi slider to the input. You can assign a button to and a fixed value like 50% but that is it. This seems like a problem, is this not possible?

I understand how the matrix works that isn't the problem, it's how the application handles it. Let me know if I wasn't clear on the problem.

I also know how the find function works, that isn't the problem it's again that I can't assign a fader to value because the parameter wants a value for the first item which forces it to ignore the midi value.

That doesn't work.

Afaik you need vMix activators to get feedback to your MIDI device, but there are no activators included for the volume levels of the channels (https://www.vmix.com/help23/index.htm?ActivatorsEdit.html). So you should be able to adjust the channel volume levels with shortcuts on sliders/buttons (I don't know what "doesn't work"), but the slider won't represent the current state of the channel's volume on your device.
