There is no need for :duration here but can be added.

For edit etc... we use the dictum function.

The omn-replace should be removed from the system. Possibily in the future the function will stop be documented.

I wrote my own little rk_omn-replace to see what could be done with :duration etc.

Could you give an example how (rk_omn-replace :duration (rnd-sample 100 '(0.5 0.25 0.75 1.5 2)) (rnd-sample  100  mat)) could be done with dictum.

How is :duration addressed in dictum?

The new version works with :duration in omn-replace.

:duration values are ratios and must be positive.
