It's amazing how much I've learned from you and on this list (well, that and
having put three VCO3's together tends to make things sink in) - I mentioned
that to Thomas as well.  He said that he'd thought of that, but wanted to
preserve the linear FM as it was (he mentioned it as being a balancing act).
At that point the LF442 was working quite well, so I never did try it, but
I'll give it a go when I'm more lucid.  Right now I'm pretty punch drunk
from very slowly putting the page up for three nights in a row over dial-up
on a cantankerously bad ISP (up til well past 1:00 each night), so it may
not be til tomorrow or this weekend.

Cheers,
Scott
