If I would get two mixers, I would choose A-138b (exponential) and A-
138c (linear bi-polar). On A-138c I would enable the offset generator 
feature with the jumper.
 
Mixers with linear control are usually recommended for CV mixing. 
However, I prefer logarithmic: When I apply small amount of modulation, 
I seem to need respectively fine control as well. Ideally, for CV 
mixing, I would prefer exponential bi-polar control, but such isn't 
available perhaps for technical reasons.
