   You are correct.  The only thing CEM in the OB-X is the 3310's.  
Everything else is straight out of the Oberheim SEM.  I have always 
wondered why they didn't pull the high and bandpass modes out from the 
filter.  They could have easily put three VCA's in and put three mix pots 
on the front panel.  It's a tempting mod.  :)
