Being a new DX7 owner, I too wanted references for information both
for programming, and for some home electronics add-on projects.

Yamaha sells three manuals which may be interesting.
All three together go for about $24.

1.  DX7 MIDI Data Format Manual

2.  DX7 Service Manual

3.  DX7 Technical Guide

Contact Yamaha at 800-521-9479 (parts) for the books.
Their sevice number is 800-854-3619  (fyi).

Of course, the owner's manual (blue cover) has a lot of 
operational information in it.

I bought the translated Japanese book already mentioned on the net, and I
think it is pretty good.  You can tell very easily that it is a DIRECT
translation from Japanese, and it does lose meaning sometimes because
of that, but the principle are enunciated, and the diagrams help a lot.

So far, my approach to learning how to program the machine is to disect
the factory presets.  This would be facilitated by dumping the parameters
to a computer via MIDI so they can all be examined on a one page display.
I don't have that yet, so I transcribe the parameter settings onto the
DX7 voicing data format pages supplied in the owner's manual.
These settings and the effect of changing various settings must be studied
and documented.  Eventually, with enough experience under my belt,  
(It stinks, but there ain't no substitute for experience!) I will develop
a feel for it.

If there is an easier way, I'm all ears!
