I bought the Minibrute in August and hasn't given me any problems until I turned it on yesterday. The octave selector isn't working, I can't work the LFO rate at all, and the Arpeggiator's tempo selection just stays at its fastest rate and can't be slowed down whatsoever.
I must emphasize the fact that this synth has been in a tidy case and has not been tampered with or mishandled in any way since I bought it.
If anybody has any suggestions on how to handle this matter, it wouldn't be greatly appreciated. even though I'm half expecting to be told something along the lines of "Oh dude, your synth is fried. I guess you'll need to take it in to get repaired. Hope you have a warranty!"
