Humaniser
-
Here's a humaniser script. It basically applies a random adjustment to all the parameters that have a setting above 0. There are tooltips to explain each control. All bug reports and feedback/suggestions welcome.

You're on fire :)
The code looks fine (nothing to improve there except for maybe not writing an equation like this :)
((Math.random() * (127 - -127 + 1)) + -127) // better - if I got the math right: (Math.random()-0.5)*127Unlike a C++ compiler, the Javascript interpreter won't optimize this into a literal but calculate it each time (it also should be easier to read).
But there is an issue when using the noteOn random delay and very short notes which cause stuck notes if the delay is longer than the note length (because then the note on will be delayed after the note off. You'll need to add the note on delay to every note off delay with the same note number (not 100% bulletproof, but better than the current solution):

Aha that's interesting, I tried with longer note delays and got stuck notes - now I know why :)
Edit: Here's the revised version.
