[sdiy] Combined CV/Gate on a cable

[Tim Parkhurst]

I worked at Apple for a little while, and one of the things planned for the
(then) new notebooks was a mini phone jack and plug with FOUR signals and a
fifth for ground. This was to accommodate some extra AV I/O without having
to add an extra connector. I suggested a mini-din plug arrangement (like an
S video style), but this was quickly vetoed because it wasn't pretty enough.
This custom jack was going to be hideously expensive, and I left before it
was finalized so I don't know if it ever happened (this was a little over
two years ago). Side note: Apple has all their I/O jacks custom made so that
they all line up (take a look at an Apple notebook and you'll see that the
centers of all the I/O connectors line up). So if this jack ever made it
into production all you have to do is scavenge some, and then put CV and
Gate for TWO Voices on one cable...

And yes, I'm being just plain silly. :) And trying to keep Magnus awake
during his meetings. Best of luck Magnus, I've been in some meetings like
that!
