Split input / Mute output

Hi, first of all I love my Morningstar devices, it is very well designed!

I’m looking for a way to split my mono input into two parallel path, and on top of it, I need the ability to mute either outputs. All of this in simple mode.
Would it be possible?

I’m not sure that’s possible in Simple Mode but definitely doable in Advanced. Is there a reason you can’t go that route?

I want to be able to switch off some loops. I’ve seen that they impemented an output merge function in Simple Mode. Split inputs might be not so different.
Is there a way to mute an output in Advanced Mode?
