[sdiy] Reaktor and CV scaling...

[synth at charlielamm.com]

My soundcards (several of them) are cap coupled at their output
apparently, so this doesn't work well for me, but, maybe I should try some
other cards....

But this does present an interesting idea....one of my cards has digital
SPDIF I/O, what's to stop me from making my own D-A converter and not cap
couple _its_ outputs? Then, I believe this would work......hmmm....
