Chiming in...

I'm programming a little DSP app.  Its supposed to be a little midi
controlled finite element string model, but its not working right yet and
makes some GREAT white noise... kinda expensive for just a noise generator
though...

Made me think of you guys...

Christian.

Yo,

So maybe its time for me to break out the magical
Xilinx parts and make a spiffy digital noise genny.

I'm thinking about having two seperate chains clocked
by prime divisors of a main clock. This way you can
have truly different noise sources. If you use taps on
the same chain, you just get a delayed version of the
noise. So a pair of 32-bit shift registers plus some
fancy dividers in front, and all the i/o lines
dedicated to bringing out taps. Sound good?
