Hi All,  For the Do-It-Yourselfers wanting MIDI control, check out
http://www.ucapps.de/ , go to the forum and look at the MIDIfication
thread.  Also check out http://mmd.foxtail.com/Tech/mvdReijden.html
for information on how Willy van der Reijden used the MIDIO128 version
to add MIDI to his Frati-Hymnia Orchestrion.

The schematics, board layout and software is freely available for
download, as long as it is not a commercial venture (see the FAQ), and
pre-made circuit boards and kits are available.  A lot of the web site
is devoted to sequencers and synthesizers, but there are quite a few
of us working on adding MIDI to pipe organs, electronic organs, band
organs, etc.
