I walked through the organ rally at Knoebels Amusement Resort and am
now inspired to add percussion to my organ with MIDI-controlled pipes
and bells.  See http://www.youtube.com/watch?v=csI2VcpNnOA
 

I could buy a new beater mechanism but that's no fun.  I can't seem
to find a used one to fix so I'll have to make one.  How do I go from
a MIDI snare drum music line that has one output to making two beaters
"roll" on a snare drum?  Do I need vacuum?  Where can I buy or get
plans to make a beater mechanism?  Any help to get started would be
appreciated.

Thanks,
Bill Clark
