As far as I remember, Kronos is not class compliant. Drivers for Korg stuff can be a headache. If I were you I’d get a USB to MIDI interface and just connect the Kronos by MIDI
Note also that by default their sliders don’t generate CC messages
I have no idea — I don’t know anything about key largo — it would have to be able to merge incoming MIDI messages from the Kronos into its USB connection.
Exactly, if you need to switch from keyboard controller to keyboard controller, it will be interesting for you @DaveSchulz to own a DIN5 to USB MIDI interface and a small control surface (Korg NanoKontrol or whatever) you know and can bring with you everywhere.
