Hello everyone!
Just to let you know that i was in the batch of people who have some problem with cutoff moving by itself!
Maybe it will help you but i just discover that control pedal assignation ( in the CONFIG MENU) of the virus ti cause some problems. Even if no control pedal was plugged into the keyboard, this last one send midi at 127 signal to your sequencer even if you don't touch anything.
I don't know if my unit is defect so i'm waiting for an answer from access support. If you think you have the same problem, just try different assignations like amp attack, cutoff 2 etc. to see if it change randomly by itself after a couples of second or minutes. Set it to off to see if all problems gone!
Hope it will help some!
Have a good day!
