OUT OF PRODUCTION! New version is on the way!

The most precise emulation of classical duophonic synths behavior and easy to program for any MIDI keyboard.

For ultimate precision we used Linear Technologies 16 bit DAC, and included several features not found on midi-CV interfaces around – MASTER TUNE and analogue GLIDE potentiometers, exact emulation of two voice paraphonic synthesizers (ARP Odissey and Polivoks, for example) behaviour, where the single gate is high, if any of two keys on the keyboard are pressed, as well as CV IN for more versatility of VCO control. MOD OUT is easily programmable for modulation wheel or note velocity CVs.


  • Master TUNE
  • Analogue Glide
  • 2xCV out
  • 2xGate out
  • Mod wheel and note velocity CV out
  • 2xCV inputs
  • 1 Voice/2Voice switch
  • Easy MIDI channel selection
