Why would you use the I2C instead of the 8 0 to 10v and 8 offset pots 
for a 16 step sequencer?  Your original approach seemed quite elegant.  

Wasn't the first approach faster for response times?  Is the lag 
between turning the pots and the output using I2C noticeable/greater 
than the 0 to 10 +/-5v pots?    

Just curious what the drawbacks were to the first approach.
