Strengths

  • More affordable and accessible entry into modular patching than a full Moog or Buchla system
  • Normalized connections mean it works fine unpatched too, easing the learning curve
  • Rack-and-keyboard combo format is more compact than a sprawling full modular case

Trade-offs

  • Fewer module types and patch points than a fully modular system limits deep sound design
  • No MIDI on the original, requiring a CV/Gate interface for modern integration
