[sdiy] Precision voltage offset

[GothGeek Sysadmin]

I've been looking around for some circuit examples and have had little luck
and I just dont have the knowledge to do this without working from example.
( I can build anything, designing on the other hand is more problematic,
unless I can work the Lego approach or its digital )

I'm trying to offset a CV by a set amount.  Offset it down in fact.  The
idea here is to offset F0 to 0 volts so I can use a standard Midi/CV with
my Moog without having to patch it to a keyboard and use its transpose
feature.  ( yes, I'm on the same quest I mailed about a month or 2 ago ).

If someone has a circuit for this, would be great. Give me something to do
tommorrow unstead of watching whatever marathon is on TV and cursing about
eMagic logic...
