Does anybody else find it frustrating that you can’t turn KeyJazz off?

When programming i like to play into the tracker as it’s running. If I want to do something monophonic in a old school tracker stylee, it sprays all these notes and tracks which i have to go back and delete, making working slow and annoying. Nu-renoise has good new features, but this KeyJazz thing is wack.

(i’m not being dumb and missed something? there is no option?)
