Elektron Musical Instruments

My sidstation has started randomly changing settings.  I know it's 
not my equipment sending messages because it does it w/out the midi 
cable plugged in.  The settings will change on their own anytime.  I 
watched the midi channel change from one to 16 (it likes to stay at 
16 for some reason) and the sync and RM cut on and off at will.  Has 
this happened to anyone else?  Any help would be much appreciated.
