I am running Ableton Live 11 and recently upgraded my Mac to Ventura OS 13.6.5. Since the upgrade, I can "see" my Kontrol 49 in Live Preferences as a "control surface" but cannot see the controller on the list of "inputs". The controller lights up etc. and appears to function OK, but no signals are being received by Live. It was working flawlessly prior to the upgrade. I have tried all of the trouble shooting tips and nothing has worked. I have an M-Audio Keystation Mini 32 controller that works just fine. I have tried uninstalling all NI software and leaving just the Apple MIDI drivers to deal with things but still to no avail. Could it be that my much-loved (and somewhat elderly) Kontrol 49 is not supported by the Ventura OS? The Kontrol 49 works perfectly when connected to my son's PC running Windows 10. Many thanks for any help.
