I was unsuccessfully trying to update to 2.0 using midi ox.  
Each time the evolver would either drop out of the first 32 step 
countdown or it would freeze during it, in which case I would need to 
unplug it.  I tried changing the output buffer to 1024/128 and other 
settings.  Well Finally it froze again during the 32 countdown but 
now when I plug it back in nothing happens, it doesn't load up, no 
lights except sometimes the 7 column light comes on.  I'm afraid it 
might need to get a new PIC or worse.....I was pretty dead sure that 
it wasn't doing a binary countdown when I unplugged it, it would stop 
during the 32 step countdown.......anybody got a clue whats up?  Many 
thanks...........
