@Mike > Best not to void the warranty by opening it. I would first suggest you try using a MIDI monitoring application to diagnose if it is indeed "skipping" information. Try MIDI Monitor (OS X) or MIDI-OX (Windows) and see if the encoder reports an abnormal value return when rotating it (eg. inverted numbers from what's expected). If it does, in fact, show a problem, you'll have to send it to Pioneer or take it to an authorized service shop for repair -- you can find the Pioneer technical support contacts to the right. --->
