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.
