Dave Smith Instruments SYNTHESIZERS

Greetings,

Just got an Evolver, and somehow, banks 1 and 2 have emptied themselves!  I 
plugged in the unit at my friends house, and bank 1 was ready to go.  hit start, 
everythings  fine.  Unplug the unit, drive back home, plug it in, and bank 1 and bank 
2 are empty!  No sequencer movement or clip led indicator.  Switch to bank 3 and a 
few patches are playable.  I repacked the evolvder in the container it was sent with, 
including the foam brackets.  I don't understand how I cou;d have erased thosebanks 
but I guess i did.  

Now, is there anyway I can restore the factory settings.  If not how do I reload the 
patches?

Sorry for the basic question, but I'm a little anxious right now.

Regards,
Stephan
