indeed, pyo looks really cool, kudos ;)

a couple of remarks with your example though.
my sc example description was not 100% accurate:
the random freqs have exponential distribution (ExpRand) and Splay does 
the stereo mix down but with a level compensation (equal power) so you 
don't blow up your ears/pa like in the above pyo example :p

also, running this pyo line uses 25% of my Core Duo 1.83 while sc 
example uses 15% (and I'm not running excellent Tim Blechmann's 
multicore-aware sound server supernova, just default scsynth)

BTW, (getting a bit OT here) I have some questions about pyo.
is there a way to use double precision ?

$ >>> from pyo import *
$ pyo version 0.5.0 (uses single precision)

for the Server to boot properly, I have to start jackd, then 
Server().boot() gives me an Error with PortAudio incorrect channels 
number (???), stop jackd, and then Server boots fine..
it seems also that it segfaults easily.. no time right now but I'll make 
more tests some time...

cheers,
