Up until this morning my S2 MK2 worked without any problems. Now, when I try to use it faders and knobs behave strange. For example, volume faders control both deck volumes at the same time. If both faders are at the bottom and i push right one to the top, both volumes go to 50%, when I then push left one to the top both volumes go to 100%. Also, volume faders are moving tempo on deck A and cross fader. Cross fader does on the device does not work. Most of the knobs have similar problems. I have tried device on 2 different PCs and restarted to factory defaults.
What can be the problem?
