"Carefully", heh heh.

[embarrassed] Not live, It's a sequence.  I started with a pad melody I played on my keyboard that
was using the pad sound.  I edited the MIDI events.  

Once I had the pad track the way I wanted it, I copied the track and offset it's timing by 2
measures later.  This track was assigned to the FM bell synth.
