"Novation Supernova I, in excellent condition (apart from some marks on the body).Perfectly functional and used to create sounds (it lends itself very well to editing and is also quite fast as an interface).
In fairness (unlike other people who would sell an instrument without saying anything: I have had several surprises, both from private individuals and dealers and this is absolutely not acceptable) I inform potential buyers that I had obtained this Supernova with a defect: some parameters tended to be displayed randomly on the display (it is a problem that has happened to someone who owns this model), so I replaced about 17 potentiometers and 6 multiplexers/Demultiplexers, also following advice from Focusrite/Novation itself, which I had contacted to get some advice.
Further clarification: only on the front panel board (the motherboard is perfect), there are slight marks (slight, don't start making up mental movies) in the points where instead of screws, Novation has placed nuts to then fix this board.
Also, I resoldered about 2mm of track relative to the central pin of the Attack potentiometer of the first envelope.
One of the buttons (perfectly working), exactly "Env 2" on the controls panel of the "Filter" section has a part of the membrane (internally, you can't see it from the outside) slightly damaged, so if you remove and insert the button cover (obviously if you try to remove the front panel board), the same button cover tends to remain in a non-perpendicular position.
But I repeat, everything works correctly."
