Hi Martin
  > Will the internal CV automatically be bypassed if I plug something 
into the CV1 jack on the A-110?
Yes for newer moduls. As far as I remember the first series of A110s 
(from 1996) did not use the normalling switch contact of the CV, but had 
a soldered wire jumper (this jumper still exists in the later series, 
but the socket contacts are no longer short connected).
If buy a used VCO, you should have a look at this. The version number is 
printed on the pcb like "A110 VCO copyright 1997 V3" (upper half about 
at the height of the tune potentiometer)


> Same question goes for internal gate. Will plugging something else into the gate jack on the A-140 ADSR bypass the internal gate for this module?
yes.
