Elektron Musical Instruments

Just picked up a new monomachine after being without one for most of the year...  I saw that 
the o.s. had been updated a few times and went for it.

Well,  now that I've started fooling with it, I notice that there seem to be plenty of bugs left!  
Randomly changing kits when sequencing, freezing up when changing sequencer length, etc.  
At least the SQUEAL is gone.

Would like some feedback from some users as to how buggy it remains - or if I just need to 
do a fresh install or something.  I only have a couple more days to return it if I choose - don't 
want to, but if the damn thing switches kits or freezes this often I don't want it.
