[sdiy] Two questions - VCO standards and Differential Op-Amp Circuit

[harrybissell]

LOL... and if everyone else would get on board we'd have...
a standard   :^P

Even the people on s-diy cannot come to a concensus... prlly because
they all have some prejudice. My 'xxx' synth uses 'yyy' so that
should be the standard.

Maybe the best solution from a studio standpoint would be a module that
scales and offsets a CV to suit.

I remember driving the ProOne from a TB-303  (yes, children... they had
TB-303
back in grandpa's day. We just thought they sucked, and sold them to you
for cheap :^)

I built a CV converter that changed the pitch by two octaves to get into
the
right range.

But I'm all for a standard...  (but not holding breath :^)

H^) harry
