autoknob
knob with an inbuild (randomisable) automator and pattern selector for live use. Doesn't save it's patterns! Pattern size and amount of patterns can be set using the attributes. you can randomise just the selected pattern or all patterns at the same time. Use the max/min knobs to set your desired output scaling
