I had this working perfectly for some time, but after a while I started to notice a problem. The faders, don't seem to send any data for the first quarter of their length. In other words, I can move the faders about 2cm before my computer receives any signal from them. The rotary knobs on the other hand still seem to work fine.
I suspect this might be a tricky problem to diagnose but does anyone have any idea what might be cause of the issue?
