You can't get the whole instrument to follow any jack and knob combos and the external 
CV seems to have been intended for modulation, and only one envelope will respond to 
the Trig in.

What I figured out was I could tap into the keyboard jack by unscrewing the plug. That way 
I could see which pin is what. I posted my findings on Analogue Heaven years ago though 
I've heard from someone with a different keyboard connector. Anyway one of the pins is 
like an offset for the duophony. You'd probably not want to mess with it until you master 
getting CV/Gate to work. The other thing that really threw me for about an hour is that 
when the EML receives a gate there is an internal buffer that samples and holds the CV 
coming in when the gate goes on. So if you are tweaking the CV on the expressionist you 
won't hear a change until you send a new gate. This might be the reason for the CV input 
jack that seems meant only for modulation. You can't modulate your incoming CV (though 
obviously there are many modulation opportunities within the EML.

Also, while it may be obvious for "old pros". I found the best way to get it to track is to 
temporarily forget about pitch, just get one octave to respond to one octave even if the "C" 
sounds as an "F" a quater tone sharp or something. Once you get your octaves to be 
octaves then it's a piece of cake to just make the C to a C with tuning
