Hi,
I am new here. I have owned a Theremini for over a year and last month took possession of a long-ordered Claravox Centennial.
The two instruments are chalk and cheese in terms of consistency of control.
I have spent most of my time on the Vox exploring "traditional" (analog) and must admit to goose pimples when the first waves of silky smooooth bass rolled over me - lovely tone indeed and so much more controllable. I have only briefly dabbled in "modern mode", but in traditional mode love the linearity of the pitch field (remembering I am coming from Theremini territory). Initially intimidating, I am getting used to the front panel knobs of the Vox, noting they are encoders rather than potentiometers. By the sounds of it my order arrived fairly quickly (4 months), but am really happy with the sound, feel, and control it affords.
I spent a while playing with the Theremini editor, it is loads of fun and affords a lot of control for creating effects and different noises - I see the Vox has an editor also, and it looks even more feature packed, but that can wait until I am better at traditional mode. I have no other theremin reference, so cannot compare it to anything but the Theremini.
I look forward to exploring the forums further.
