Happy? Accident with CEM VCO

[R.Fahl]

Tonight I was testing another CEM based VCO.  Before I plugged in the 3340,
I tested the power supply points to make sure things were connected
properly and nothing was shorting, etc...  I noticed that the negative rail
was a bit dirty.  Lots of oscillation.  I thought it might just be a bad
scope connection, as I am using an old scope, so I power down and install
the CEM.  I power back up and I have totally dirty waveforms.  I decided to
listen to them just for the heck of it... and they sound great!  They sound
like those chalky thin FM sounds you get on those 4 OP Yamaha FM synths,
like Ghosties on the FB01.   I'm halfway tempted to leave the bug alone.
That's why I love building my own stuff.  I just never know what weirdness
I'll run into.

"The complexities of developing a jet engine were sometimes overcome in
almost simplistic ways; when the 004B-1 began to have vibration failures in
the turbine buckets, a professional musician was hired.  With his perfect
pitch, he could determine the natural frequencies of individual blades in
an assembled turbine wheel by means of a violin bow.  His gentle bowing led
to the solution of the vibration problem by tapering the blades slightly to
increase their natural frequency, and by reducing the operating RPM of the
engine from 9,000 to 8,7000 RPM."  From "Messerschmitt ME 262 Arrow Into
the Future" by Walter J. Boyne
