[sdiy] DX7 hacking?

[Barry Klein]

When the DX7 came out I was one of those in awe.  When I compared it to my
simple modular I sort of just gave up on modulars and building and just
spent time playing.  Then I started buying analog synths in need of repair,
fixing them, playing them for awhile, and then sticking them in the garage
with the rest.  As analogs were not as well favored as digitals back then,
analogs needing repair were affordable - so it was a satisfying pastime.
Going through all this helped me learn a bit about synths that I never would
have been exposed to earlier - yet alone have the money to buy back then.
So anyway, as I progressed through this I occasionally went back to that DX7
and enjoyed its unique character but hearing it in most every patch was
audibly boring.  I didn't get into effects devices like Eventide or the like
until much later.  I always expected someone to hack the DX7 into more of a
monster.
I never saw it happen.  Has anyone ever made any progress or attempts? -
something that gives it a sound character other than FM?  Is the design too
"purposed" for FM to alter?
I'm sure I could just forget about it and realize that newer synths probably
have the FM as just one sound option.  I just don't have anything that new.
