Pros & Cons

👍 Pros

  • Offers an authentic reproduction of original "System 100M" circuitry for a vintage sound experience
  • Features two independent lowpass filters, each with dedicated cutoff frequency and resonance controls
  • Provides extensive connectivity with three audio inputs and three CV inputs per filter, each with an attenuator
  • Includes a switchable 3-mode high-pass filter for each VCF, expanding sound sculpting possibilities
  • This module is inspired by an amazing Dual VCF module from the 80s, bringing a classic sound to modern Eurorack setups

👎 Cons

  • Requires additional Eurorack components and a power supply to function, as it is a module
  • The Eurorack format may not be suitable for users seeking a standalone, all-in-one synthesis solution
  • Detailed understanding of modular synthesis is necessary to fully utilize its extensive CV input capabilities
  • Absence of built-in sequencer or modulation sources means external modules are needed for dynamic sound changes
