Thank you voxman55 for your effort, it's much appreciated.
Sadly I'm stuck with the same problem though.
And to answer your question, yes, the MODE-button has worked before, but it just stopped working one day.
It's so new I haven't even played it live. I've just been learning the device and trying out sounds at home.
I ran the 1.30 update without any problems, and it worked just fine with the update. The button stopped working a few days later.
I've tried both Factory Restore and Clear Everything, and it didn't work.
Everything I made was backed up, so all those hours aren't wasted at least.
I just got an e-mail today from the vender and they'll take it back and send me a new one.
