The Midi Echo setting was similar - it would take all messages received on the input ports and send them back out the output ports. This can result in loops and other undesirable behavior though. I would recommend using something that can route the MIDI messages the way you want. One thing you can do is use an application like loopMIDI to receive the MIDI from the keyboard, then loopMIDI can send the messages back out to both MobileSheets and whatever else needs to receive those messages.
