Hi Kassen & Hans,

That's very sad! A seed is perfect to get a repeating pattern, but sometimes it's nice to turn off the seed to get non repeatable values.

So the only way is to delete the seed and restart the sketch?

thanks!  

Hi Lars!

if we use a random seed, f.e. Std.srand(120); 

will this affect all the random function inside the sketch?

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.

 

and if so, how can we turn it off?

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.
