Very nice update, thank you! 
I have a general question regarding Duplex and own tools. Is it possible to connect Duplex in some way with the gui of own lua tools? So if there is something changing in the display in the gui of the tool, it would be nice to send it to the midi controller (say launchpad) and have the changned view in the midi-controller as well. In my case I am talking about the StepSequencer I created (see forum post), which can already be controlled via Midi hardware with MidiMapping. A nice feature would be the following: If the Editstep or Page is changed (which changes the view of the highlighted steps in the sequencer), the change should be reported to the connected midi-controller and display the new view. It would be nice if you can give me a hint, if and maybe how this could be done with the help of Duplex?
