Is it possible to make something like this as we see in Reaper here.
This would possible be of great interest for many, it would probably work best on a drum track.

But for Quantized piano track, it is probably not that good, but i would love to have an option
for something like we see in reaper.
In the ( piano roll of sonar ) and to choose " Humanize " from there.

Problem may be for piano to get good enough result, so it sounds like an actual good " played " performance.

This may be a small request, but probably a huge challenge to make.

At least i would really find it very useful, if it was possible to do.

( PS : i have tried the " HUMANIZE " CAL script, without any good enough result on the midi piano track. )
Also GROOVE Quantize function.

Just a thought....

Sonar has a very comprehensive quantise function that allows for a great deal of fine tuning so that the end result may be humanised.

I don't know how reaper does it.

I think adding a humanizing algorithm to the Quantizing tool would be really cool. If reaper could come up with it, I'm sure Sonar could achieve something similar. Just another tool that could be useful or creative in the right circumstances. 

IIRC the humanize CAL is not intuitive, small value insert BIG changes, whereas large values (50+) do smaller changes. I forget the details of that CAL, but you can open it with NotePad (is a simple text file).

What's wrong with right-clicking on the clip and choosing Process Effect -> MIDI Effects -> Cakewalk FX -> Quantize or Velocity and then using the Random/Randomize bar??
