It's worth noting the most important difference between the A100
theremin system and a Moog Etherwave--the Moog, awesome as it is, has
essentially one sound--a sine wave. With the theremin controller, you
can in theory use it to control any sound the modular can make, and
the modular can make a hell of a lot of sounds.

I don't have the theremin module, though--Florian, how do you like it
in terms of responsiveness How susceptible is it to interference
