Keyboard note # 22 (Bb) is set to Start/Stop Recordings (all)
Notes 21 (A) Previous Song and 23 (B) Next Song still work.
I confirmed the Bb is sending Midi Note On/Off.
I tried deleting and resetting note 22 - no help there.
OK Panic's over.
I had restarted the keyboard but not the Android Tablet before I posted.
Now that I restarted it everything works again
