Free tool — see exactly what kind of converter connects it to a modern MIDI setup.

Strengths

  • Aggressive, self-oscillating filters give it a distinctively raw, biting analog tone
  • External signal processor input lets you run guitars/vocals through its filters
  • Patch bay adds semi-modular flexibility on top of the normal hardwired signal path

Trade-offs

  • Only duophonic, so chords beyond 2 notes aren't possible
  • No MIDI on the original, requiring a CV/Gate-to-MIDI interface for modern integration
