Roland AIRA defective, Who do I contact?

11 months ago I bought the AIRA TR 8. And now I got this glitch,

has been confirmed error by Gomi that works for Roland.

He told me to contact sweetwater, but will they send me a new one?

or should I contact Roland? It has one year warranty with Roland.

Idk about sweetwater....
