Hi Tim,

According to the Digisound construction notes..
"White noise is defined as having equal energy per cycle and pink noise equal 
energy per octave. To derive the latter requires the white noise to be filtered 
at -3db/octave and since filters usually have slopes of 6db/octave, a 3db/octave -

-

has to be approximated. Note that other variations in noise colouration may be 
obtained by filtering the white or pink noise with Project 80 filters 80-6 or 
80-7. The low frequency noise (sometimes called red noise) is obtained by 
filtering the pink noise using a 6db/octave with a cutoff frequency of about 16 
Hz".

How does it sound? dont know yet but hope to find out soon...

cheers...
