If your midi device works with the dot2 onpc without any additional software - then yes - it will work.
Otherwise - no
Because dot2 does not recognize CC commands (which need to be converted to midi note)
It's definitely better to connect your laptop - and run dot2 onpc in one session
Additionally, you can also run a 3d visualizer - which supports programming
I Don't need any additional software. I just plug the launchpad into my laptop, run Dot2 onpc and have a session with the console. But I would like to use the launchpad without the laptop...
