the problem is of course, that when opening your patch everything
happens at the same logical time; so seeding your [random]s with [time]
(and the like), you will actually seed them all with the same seed, thus
producing the same series in all instances of [random].
using [time]+[realtime] should in theory work;
another idea would be to add a different offset to the basic [time]
derived seed for each [random]: so all seeds are different (though
related), which should work fine.
the really nice solution would be to use a [time]seeded [random] to
generate the seeds for the other [random]s.
Or have a single random generator inside pd that feeds all the random
objects.
Also /dev/hwrandom on some machines will give 'real' random numbers that
don't need to be seeded.
