i have a nord lead i got at guitar center used, for $200, its pretty beat up, its missing a D key, its got a weird mathmatical equation hidden under a psychadelic sticker of a man walking in space toward a burning sun, its pretty heavy stuff. This keyboard NO DOUBT belonged to a real lunitic before i got it, and im wondering where i can A. get a new D key. B. get an owners manual that i can read cuz the one on clavia's page sucks. C. can anyone instruct me on how to reset the factory settings? the guy that owned it before me has some pretty scary sounds on it, i dont know how he got them, but they truly scare me. like event horizon meets the exorcist, and im an avid fan of horror flicks.
