in zexy there is a very naive(!) (and superfast) pitch detector [dfreq~] 
which just counts the zero-crossings.
however, i don't think that it might work with a good saxophone player 
though (i assume that sounds will be very noisy)
(actually i have used it only once where we had to detect the pitch of a 
theremin (== very few overtones))
