A comment here on rand.  The period of rand in csound on most platforms is
65536, or less than 2 seconds of white noise at 44.1 kHz.  The repeating is audible.
	I have code for a random number generator which will repeat for most seeds
about every 1 billion years at 44.1 kHz.  The low end is about 100000 years. 
I would be happy to pass this on to jpff.  The question is: Do we replace rand
with the new code or make it a new ugen, to preserve the flawed character of
rand for old scores?
