The midi feedback is a great addition, thank you 🙂 What I meant by ‘latching’ was the behaviour of some midi controllers in what is usually either called latching or toggle states, in this state the controller outputs cc/note with 127 value when turning on (and usually lights an LED on the controller) and then on the next press outputs the cc/note with a value of 0 (and usually deactivates the light on the controller), but I realize now that because of the need to make a distinction between short and long presses in logelloop this is not really possible.
