Lost all knob & pot functionality on Virus TI [solved]

The knobs and pots on my Virus TI2 ceased to produce any effect when turned. Master Volume control still works. All buttons are fully functional, and all sub-menus are browsable. How can I fix this? If I use factory reset, will my firmware for Virus Control be removed (do NOT want to re-install that).

I'm a new Virus owner. Everything was working smoothly with hardware as well as Virus Control through Ableton Live 9 (OSx 10).

I've been messing around with sending other instruments through the input, clicking around in the config menus, and generally messing about in the Virus controls and parameters. Perhaps I somehow disabled knob (pot) functionality?

Very odd occurrence, could not find anything similar via 'Search'.

Please advise

Issue was caused due to 'Off' value in Config > Knob Behavior > Response.

Here is what Access Support send to me:

"This sounds like the "knob target" parameter in the units' CONFIG Menu is set to "midi" and not to "internal" or "internal + midi". Please check this on the device."

Hope you resolve your issue.
