Thanks for the question and constructive suggestion.
No doubt, it would be more intuitive and flexible to have a dedicated gesture to en/disable the AI mode.
The reason or motivation behind the current setup is that, writing automation or changing parameter level is a serious business in music/audio production as we all know. Thus, by requiring users to (de)activate the AI mode explicitly, the absolute reliability and accuracy is guaranteed when using the corresponding virtual control.
As a result, it rules out the possibility of any accidental mode switch amid a serious mixing process, take for example, if a false detection suddenly occur at the sensing layer. We don't wanna trigger a STOP accidentally when writing our automation smoothly during the process, do we?
As the technology gets more mature and robust over time, things can definitely be improved in this area. Thanks again.
