This is not so much an answer, but rather a confirmation that MIDI recall of Scenes/Versions/snapshots is a KEY FEATURE REQUEST for using Studio One in a Live setting!
The Show Page in its current form is really only useful for backing tracks, and really people can just use their iPhone or MainStage to do that.
Having the ability to snapshot (more like a song version than a Scene, as it's everything, not just mixer) and then recall it via Control Link is huge advantage for PreSonus - especially given Atom and StudioLive..
