Last weekend at the COAA rally in St. Paul, Minnesota, three
20-note organs were linked via MIDI to play in tandem.  Bill Klinger's
home-built organ was supplying the signal to Jim Partrick's OSI organ
which in turn was sending on to Carl Cavitt's OSI organ.  Carl's organ
has a motorized pump and a set of bell bars, also MIDI controlled.  All
three organs are using the SD-MIDI ReadeR and j-Omega magnet driver
cards.

A short video on You Tube of "The Cuckoo Waltz" shows the end result:
