I just ran into a "Copy Pattern A to B" bug in the sequencer, and I have the most recent firmware. (3.0.6.1039) 
Pushing down the A button does not load the expected "Copying Patt A to B" screen. Instead, holding down A causes the machine to cycle forward: from A to B, to Record to Play, to Spice, etc.
Turning the machine on and off does not fix this bug. Working in a NEW Preset doesn't fix it.  
 
 It is impossible to copy a pattern from A to B (or B to A). 
Pretty bad, no?
