Analogue systems

I'm thinking about adding the RS95 to my doepfer system but it only 
has 1 cv input to control the pitch. On the doepfer you have 2 of 
these. One for tracking the keyboard and one for, say, connecting an 
lfo to create a vibrato effect etc. 
How can this be achieved on the RS95? 
(From what I read on the Analogue Systems site there is a cv-in/vary 
input but this is used to control the sensitivity of the VCO to the 
first CV-in.)

Thanks - Mike
