> What you need to do is attenuate the signal slightly, say by a factor of 2. The A183-2 will both attenuate and offest the voltage fed into it (please read the blurb on the EMIS or Doepfer websites where all the modules are described in some detail) so you can effectively reduce the response of the A-178 theremin output. As an example, if a movement of 3 inches (or 8cm in Newspeak) causes a change of 1 volt in the output of the A-178, which when fed into a VCO will normally cause a change of 1 octave in the pitch, the attenuating the signal will moderate this. If you attenuate by a factor of 2 a 1 volt change on the input casues a 1/2 volt change on the output so you need twice as much change to get a 1 octave difference. Roughly speaking you will need to move your hand six inches instead of three. The offset control of the A183-2 allows you to choose where the voltage is in the range we use so you can effectively choose the starting pitch by adjusting this. Because Eurorack synths use the 1 volt per octave standard, you can then choose where on a 10 octave rnage you want to play your theremin.

A modular theremin give you scope to do all sorts of crazy things, not just adjust the pitch and volume. Try using a filter instead of the volume, or adding some LFO modulation to the pitch, or even all 3 at once. It's modular after all.
