Yes, it will. And this does mean that periodically resetting the seed (say at audio-rate) will turn the UGens that use noise into a sort of wavetable players; it will affect all random functions and noise-generators.

 

Well, you can't. The whole point of ,srand() is affecting the various random functions to create repeatable pieces.

A alternative would be simply not setting it, though I do seem to remember some issues with the initial seed under Windows not being particularly random. In that case you could set the seed using a amplified signal from the adc. A source like hiss from your mixer should be as random a signal as you are likely to encounter in day to day life and mak things utterly unpredictable.

Hope that helps,

Kas.
