Where do you apply humanization behaviour ? In the pattern editor, in the automation-section or via plug-ins ?
All of the above mostly using tools, now that midi plugins can be used there are pretty nifty vsti for manipulating the timing of note events. The swing dial in kirnu for example, or this one;http://www.mucoder.net/en/hypercyclic/ (also available for linux).
I use this tool a lot for randomizing/generating volume column values between set limits in a pattern;https://forum.renoise.com/t/new-tool-2-8-velocity-randomizer/38684
Still hope one day to figure out lua and hack it so you can generate more patterns/song at once, having to boot up the tool for every pattern gets tedious quickly, also to have it work on the pan & delay column would be great.
