I just got an M-audio Ozone midi interface and I'm running Reason 3.0. I'm wondering if I have a defective keyboard or are my problems normal. My problems are 1) sometimes during playback the sound gets all scratchy 2) the sequencer freezes up (or the keyboard does causing the sequencer to) when the internal fan comes on luckily I can still save the piece I'm working on. I end up restarting my computer very often and it really sucks. There are other occasional problems too but these are the main ones. Anyone having similiar problems? Any fixes other than restarting everything?
