Hi Martin, Chris,
and thanks for the enthusiastic replies!

So you also need a clean power supply and careful circuit layout to avoid contaminating the control voltage with clock signals and switching noise from the rest of the circuit.

So with one Arduino, how many chips could I control? In other words, how
many different CV channels could I get out of it?
