You need a mixer module and a fixed voltage (e.g. any active output of
a step sequenser). The A-138c mixer module has a fixed voltage on
input 1 if no patch chord is inserted.

What you do is simply scale down the fixed voltage and then insert
that into the CV2 input of the A-110. The CV2 pot is now your fine
control.

Best Dirk.
