I can't easily test it with mainstage, but are you just trying to get another plugin (playback) to sync with SL, or having mainstage itself sync to SL? You turn on MIDI Clock output from within SL's Preferences, the Latency/Misc tab. Then you'll want to route SL's midi output back into mainstage, and then enable MS to sync to it (I don't know the steps for this, or if it works!).
