Guys, is there just ANY video, where we can see how this module is operated by a professional theremin player playing a melody?

Probably not. If you read the info on Doepfer's site, you'll notice that this isn't exactly a "traditional" gesture controller. It has some obvious drawbacks, especially regarding the capacitance, that would tend to make it less of a "proper" rod or ring. It seems to me that it would make infinitely more sense to use a Moog Etherwave Plus to send proper CVs and gate to a modular, given that the Etherwave has its aerials in optimized positions already and the circuitry is designed to deal with this sort of thing. Plus, it's a wooden box (NOT metal) which should be easier to control and calibrate, and it can be located away from metal or other things that might cause an unexpected signal.
