Although I have never (yet) tried this, but if you have a Waldorf Q/Q-rack, have read on more than a few occasions where people state that most of the midi cc’s correspond with the Blofeld and make a great controller for it.
Have seen many of your music videos, providing your same Kirlian on YT, and thought had spotted a Q rack at some point but if it was in black and white, perhaps it was a Polymorph or Rave o Lution? I own an XT Rack so would never confuse it with the Q rack.
I wanted to add that although Waldorf Nave App would never replace the Blofeld or even the XT in my opinion, I recently purchased first iPad 2 and the Behringer iStudio Dock, just to own NAVE…it’s quite a wonderful sounding synth.
