Eml synthesizers

I am trying to interface my EML101 to an Encore Expressionist MIDI>CV 
converter and am having a heck of a time trying to get the synth to 
track somewhat chromatically.  The patch panel doesn't have the 
sequencer input but does have the OCS1 Ext CV in.  It seems that there 
are several interactive pots to set pitch but I have no idea how to 
make it work.

Any suggestions?
