[PD] anyone using array quantile?

[Miller Puckette]

There could be something wrong.  But array_random_bang() (in x_array.c)
cooks up a pseudorandom number from 0 to 1 (I believe) and then calls
array_quantile_float() with it.  That's exactly what connecting random()
to array_quantile in a patch should be doing.
