I was concerned about that too. Varies with the hardware, but with I'm  
able to get over +4v with an Ultralite and most MOTU interfaces are in  
the same range. I've tested it with a wide variety of doepfer,  
cwejman, tiptop, livewire and plan b gear (and others) and I have yet  
to encounter anything that fails to respond with a full range.

The most important issue is pitch tracking and by offsetting the oscs  
a bit I've been able to achieve seven octaves. I think we may be able  
to do eight with a bit more tweaking. Actually, I'm overstating this a  
bit, for example, I'm able to get seven octs with a Z3000 with the  
coarse tuning set dead at 12 o'clock. Anyway, I'm completely satisfied  
with the voltage range. Anyone want to buy a Doepfer MCV24?

Volta is a no-risk purchase. If you are unsatisfied for any reason, we  
will issue a full refund.
