Connect Korg midi controller to Eos nomad !!!

You might want to check out Chataigne, a program that can receive MIDI signals from your Korg nano and send them to Eos via OSC. It's very versatile; I suggest you look into its mapping and multiplexing features. It can be a little complicated but if you run into any issues there's an active support community on Discord that can help.

If you're looking for simpler alternatives, you could also consider Luminosus or Shift-Faders. I would note that Luminosus and Shift-Faders seem to no longer be in active development.

Thank a lot for all the information, i checked Chataigne is indeed not easy, do you already have to tutorial somewhere ?

Here's the documentation page, to begin setting this up you need to add a MIDI module and OSC module. You can use mapping to convert the midi fader values to OSC values for EOS. If you have more questions about how to specifically set this up there's a discord where you can create a thread with any questions you have.
