[sdiy] CMOS Synth

[Scott Gravenhorst]

Yes, very nice work.  Toy?  I don't know about that, and Osamu, your
English is quite good.

You've enspired me to get off my big fat butt and start working DIY again.
 I had a little problem with a heart attack and quad bypass, but I'm OK
now.  That had caused me to be careless in storing things in my lab, so
I'm now on a cleanup binge (BTW, nice to see that YOUR work bench looks
much like mine).  Unemployment for a 2 year span hasn't helped either, a
psychological downer, but at least I have a cache of parts here.  I've
still got a couple of CMOS projects hanging in limbo that I want to at
least throw at a bread board.  A CMOS Sallen-Key LowPass is one of them.

One thing is for sure, those linear mode CMOS "opamps" do draw significant
power.  Since my project is an enhanced FatMan, I think I may limit their
use to where their characteristics are desirable, such as the distortion
one gets as the output approaches the rails (can make a tri to
sort-of-sine converter).  And also as cheesey voltage controlled
resistors.  Of course, as logic elements too.

Thanks for this, but where are the sound samples?   (c:

Back to cleaning up the lab.
