Not wanting to appear biased but I can kind of understand why there isn't an overall transpose setting in V Collection, because there isn't a 'wrapper' for the entire collection where such a global setting would be hosted, except Analog Lab, which both sort-of is, but mostly isn't, a V Collection wrapper.
I'm surprised Luna doesn't have anything to transpose incoming midi notes. Every time someone tells me how out of date Logic is becoming and how it's bordering on being Apple abandonware, it doesn't take me long to point them towards some feature in it that their preferred DAW is lacking. ProTools users...well I have a list as long as a toilet roll, especially on the midi side of things.
