Eml synthesizers

Hi

I have an EML101 that doesn't have a patch point to drive all the VCOs 
(my manual says there is a Sequencer Input for OSC 3&4 but my patch 
panel says CM3 Output).  All the Keyboard patch points are outputs 
(save for glide) and the only input is for OSC 1.  Is there anyway I 
can drive all 4 VCO's from my Encore Expressionist?  Also, I believe 
the V/Oct isn't exactly 1V/Oct.  What is the best way to program the 
Expressionist to drive the VCO(s)?

Thanks in advance for any help,
