Creative Randomness

[Darryl]

The short of it: add musical randomisation wherever possible. For example, the pattern
editor could benefit from random pattern generation. Feel free to comment with a NDLR feature that could use a randomize button.

You can try using the modulation matrix to modulate various NDLR parameter. Maybe try S&H with a degree of Probability for some randomness. 

There isn't a way to address individual steps in a pattern from the modulation matrix, though it has been put on the (long) list of feature requests. There is a workaround though... if you are in the Pattern Editor, you can use a keyboard to change pattern step heights. This means, you could sequence the pattern steps using an external sequencer or software. Something like a Korg SQ-1 or Beatstep would work. Or just switch to the Pattern Editor screen to "play" the pattern with a keyboard as it runs. When you switch away from the Pattern Editor screen, the keyboard can be used to change chords.
