hello!
 
I don't know if this is a common issue, but my transposition buttons and the ribbon controller went "mad"...
You know, the two transposition buttons have 3 lights down, a center (no red light) and 3 lights up, on the 12 notes transposition scales. .  
If I'm on the center, I have no problems with the sound, but if I go up or down, the patch where I'm positioned go mad with the pitch bend range. 
 
If the patch has a default pitchbend range of -2 +2, the patch starts to alternate on the  pitchbend, like if I where touching the ribbon controller.  I had to reset almost all my patches to 0 pitchbend range, but no way to fix this with preset patches. 
 
If there's a solution for this problem let me know, but it seems like a hardware problem :(
