I’d like to suggest a feature that could be useful in both live and production setting.
Event and note probability would allow for setting a chance of specific note or event being played back at random chance.
For example: you want a certain event or drum part to have only about 30% chance of being played back, so it doesn’t exactly play back every time around.
This option would further help in achieving less stiff and robotic, and more natural, unpredictable, sound, like it is in real life.
