MIDI not working in Bias Fx 2

  • Im using Bias FX 2 Elite running under Windows 10 on a laptop and also on a desktop PC. Midi data is not being received in Bias FX on the laptop. Other apps receive it fine. I have set the Active Midi Input in Audio Settings, enabled midi and selected all channels in Midi Settings. When I try and add a midi control assignment it doesnt register any button press from my midi devices. I have tried a couple of midi devices. I have done exactly the same setup procedure on the desktop PC with the same devices and it works fine. All my drivers are up to date. The only difference I know of between the 2 PCs is that the Desktop PC is running the November 2019 version of Windows 10 Pro 64 and the Laptop is running the May 2020 version of Windows 10 Home 64

    Anyone got any ideas on how to fix this?
