Hi,
we discovered yesterday that on our Virus TI (1), there are three keys responding differently to playing velocity than others.
They react much stronger - making sound programs that use velocity difficult ("dangerous") to play.
Mechanically, they "feel" the same as the other keys, they just seem to translate the velocity in a different way.
Since the problem is shared between sound programs, it is to be assumed that this is a hardware/calibration problem.
(The keys are distributed over the keyboard G#2, F#3 and C4 counting from the lowest key on the 61-note keyboard as C1)
What could the cause be and how would one go about fixing this?
