I have built a GUI software application to edit the configuration in the Korg nanoKONTROL 1 & 2. This is an open source, cross platform application written in Python using the tkinter graphical toolkit. It works with ALSA and / or JACK MIDI. @wyleu has performed some initial testing with a nanoKONTROL2. I would be interested in any feedback (maybe via GitHub issues), especially if you have an original nanoKONTROL which it has not yet been tested with.
I do not have this device so have been coding in the dark to some degree.
You can find it on GitHub. The README should describe all you need to know so please do let me know if it isn’t clear.
This should provide similar functionality as the Windows / MacOS application that Korg provide. I have not seen that application so don’t know how similar it is to my interpretation.
