Track -> Randomize Doesn'T Work

I guess this is supposed to randomize the notes, but I can’t get it to work.
Selecting the notes doesn’t do anything either.
How does this go?

Track > Randomise randomises the parameters in the effect columns.

Track > Humanise randomises the volume, panning and delay columns to give notes a more ‘human’ feel.

There is no default function to randomise the notes themselves, but there is a tool you can use in Renoise 2.6: com.renoise.NotesRandomizer

Thanks, I’m still with Rn 2.1 so I’ll keep on using an existing .php file I changed a bit (“xrns_randomizer.php”) which also does the trick.
