Virus TI2 not producing any sound in MIDI mode, but works in USB mode

My Virus TI2 one fine day is not producing any sound in stand-alone mode. If I connect a MIDI keyboard, it does make any sound. I tried changing 2 different MIDI keyboard and 2 different MIDI cables, but nothing worked. I tried resetting the system by powering on while pressing the ARP-EDIT button, but it did not help.

For some reason, in USB mode, using Ableton Live, the Virus works fine.

I have updated to the latest Virus OS, but nothing is helping. Can anyone please help?

How do I find the "Local" settings? I have the Virus TI2 Desktop version (not the keyboard),

I pressed "CONFIG", but do not see any option to change "Local". I am at version 5.1.7.00, which seems to be the latest version of the firmware as of 29 Jan 2018.

OK. Just came to know that.

So, any idea what can cause this? Are there any other settings in the CONFIG menu?

It seems I had issues with the sound system!
