Hi,
don't know if this has been already discussed,
but could it be possible to implement a way
to randomize values (expecially notes) in negative?
Now it's possible only in positive, right?
If i have a c3 and add a value like 12
the random applies only on c3 to c4,
instead it would be nice to obtain also c2 notes :-)
Or something similar to the random plugin in live
where you can select if add or subtract random values.
Just an idea...

PS: v4 is very cool to me,
i didn't used much playlists
and now i like more the bars menu.
