It´s very annoying. For 700.- I want to just plug it in and use it in every intended possible way without any problems. In addition to that my monitor outs are quite buzzy, too and the backup function via USB doesn`t work. The reason I bought it was the form factor and its limited fx (I don´t need that much) - indeed the Kemper product I`ve been waiting for.
But I don`t want to spend another 184.- for getting it to work properly.
On the other hand I understand that you spent the money and worked the problem out for you! Thank you for your answer!
