Such behaviour could be caused by faulty MIDI commands in the MIDI tab of (one or both of) those songs.
Loading 'Unchained melody' could then instruct the keyboard to load a registration file. The keyboard will then report back to the tablet that this registration has been loaded, which in turn could instruct mobilesheets to load the 'Love Me Tender' sheet (which in turn could instruct the keyboard to load another reg file .... ) .
If that is indeed the causing the issue, loading 'unchained melody' while the SX900 keyboard is switched off, should work fine and the MIDI commands of both songs should be checked in MobileSheets .
