Anyone thinking of building their first MIDI instrument may find
my building Topsy package very useful.  This describes the
building of my compact 64-key MIDI organ, most of the text goes
into the implementation of MIDI for the first-time user, specifically
regarding mechanical organs.

It is a very practical guide to MIDI including auxiliary circuits
and some of the alternatives that can be used.  The DVD shows the
construction of the organ which includes some unique features.

I have specialised over the last 14 years in producing practical plans
to let people build their own organs.  I did this because I found that
too many articles and books on organs did not give the detailed
information I needed to actually make anything.
