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.

Oh, thanks for explaining.
"Control eurorack with Etherwave Plus" is what I am doing right now. But when I saw again those A178, I got a spark of a hope that I possibly can dramatically reduce a size of my road case (minus one etherwave, which is definitely more room to put a more pairs of socks). But I still want to be able to play all things I can do on a "normal" Etherwave.
Again, thank you for keeping me in place!
