Usually, but not always. I don't think the TWS responds to
negative CVs for example.

That should have been -2.5v to +2.5v....

Yes. AC coupling is usually only found on inputs, but some
of the early modules - Noise, old Oscillator - had both AC
and DC coupled outputs. If you AC coupled the output of
a QUO for example, you wouldn't get much out of it at
low frequency.

I think the colour system developed back around 1973/4, and
as the modules developed, the colour codes didn't always
fit perfectly, so the definitions of the colours has become
quite loose. If you think blue usually CV, black usually
audio and red usually trigger/gate, you won't go far wrong.
