Elektron Musical Instruments

Today i noticed it:
three weeks after having my potis replaced by elektron, one of the 
potis starts behaving like a crazy bitch again. the intersting thing 
is, this poti has the same problem than the other poti on the same 
place before, its seems it doesnt transmit the values correctly, so 
the values are "jumping" around...by the way, its the pot that is 
controlling the "decay"-value...
How do you think, is it a "software problem" in the md? or maybe the 
circuits on the mainboard are damaged?

Now so many pieces of my hardware are damaged and in repair, i really 
consider to start using software in future and doing laptop-liveact...
