I started having this issue a week ago and hoped 1.6.1 might fix it somehow but that did not do the trick.
I can load tracks, but I cannot play, beatjump, or jog them. Play/pause appears to work as in button starts to flash, and if i try to load a track it will say it cannot because one is playing, but the waveform is not moving at alll and there is no sound. The jogwheel will not move the waveform either, however appears to be functioning normally in that it is not white as if it is being pressed.
Do I need to send this unit back?
