Can I use A-133 as a 2-quadrant multiplier without adding an offset to 
the VC? Obviously this is no problem for all + signals like most 
envelopes, but how about for LFOs?  For example, to get a good vibrato, 
I would have to run a sine into A138c and use the offset function to 
get 0 amplitude at the maximum negative portion of the sine. Is there 
any other module that does offsets like this?
