Strengths

  • The original patch-cable modular synth architecture that defined the entire category
  • Fully modular design means genuinely unlimited routing possibilities, limited only by module count
  • The unmistakable Moog ladder filter tone in its purest, most flexible original form

Trade-offs

  • Enormous, extremely expensive, and effectively a permanent studio installation, not a gigging instrument
  • No two systems are configured alike, so patches and knowledge don't transfer directly between units
