Hi Pierre,

I play an Etherwave Pro Theremin from Moog (which is supposedly the
'perfect' Theremin) and I also tried to use the A-178 (I removed them only
recently from my Doepfer-Rack - if someone is interested in them, please let
me know what they would be worth for you to buy) modules; on both you have
the effect that an octave is not exactely linear -

so, in short: the problem you describe is much more prominent with the
Doepfer modules but present in other Theremins also...

Best wishes,
chris
