how to generate a limited series of random numbers

Question

hello everybody,

I would like to generate a series of seeded random numbers that is not infinite but that repeat itself, for example every 64 beats.

how can I do it?

thanks.

Perhaps you could generate an Array of random numbers and then use the of: message to repeatedly read from that Array?  For example, something like this:

| r |

r := Random newForKymaWithSeed: 879.

(1 s tick nextIndexMod: 64) of: (1 to: 64 collect: [:i | r next])

If you'd like to be able to change the contents of the Array, you could instead use something more like the following, in which case you could use !Trigger each time you'd like to generate a new set of 64 random values:

(0.2 s tick nextIndexMod: 64) of: (1 to: 64 collect: [:i | !Trigger nextRandom * 36 nn + 48 nn])

thanks a lot! this is working for me.
but what if I want to have a Seed that is an hotvalue?
