BJ's 4046, PM, additive waves!

[Bjorn Julin]

Hi.

Over a couple of months i have been trying to design a
discrete PM oscillator and still do so until it gets ready
for publication (if, it works well that will say) you
can go to:

http://home.swipnet.se/~w-133242/4046.htm

This 4046 design is used as a scratch pad for the
discrete PM oscillator, it was also a try out
to se what one actually could do with the 4046 PLL.

Some one on the list once said:
"One wishes that more could be done with the 4046".

Well, i think that the 4046 is a wery nice device if
one takes care of what it delivers.If it was not for
the linearity error it would have been a damn good
VCO!

The design delivers so many different wave shapes
that i got fedup by trying to draw them of the
scope screen (have no digital camera)but many
of the more interesting ones is in the graph.

A note to the sound of shape no 12, it does not look
much to the eye but the sound is really interesting.
Imagine this, a piece of styrofoam rooling down a plastic tube!!
A sort of flanging sound!

There is a wave that i have missed to draw,but sound
wise it sounds like synced oscillators.

The shape no 3 and 2 is WERY fat, fat as in 30 kilo "GREASE",
not phat, "FAT". Use those wave shapes and you have the
bassiest bass sound on the planet!Mini Moog go home!

There might be faults in the text and or design and
im listening to anyone who reports such issues.

Add the Computer Noise generator to any odrinary VCO design
and you get PM,Ring mod,PWM computer noise to your synth.
