Tiptop Audio Forbidden Planet

Resonant multi-mode filter from smooth to chaotic

8 HP Eurorack module

The Tiptop Audio Forbidden Planet is a voltage controlled resonant multi-mode filter offering High Pass, Band Pass, and Low Pass filtering simultaneously. It ranges from smooth and crisp filtering to aggressive chaos, with resonance capable of self-oscillation and saturation at extreme settings.

Features

  • Three simultaneous filter modes
  • Self-oscillating resonance
  • Dual CV inputs with attenuator
  • Independent inputs for each filter mode
  • Master volume control
  • Circuit saturation at extreme settings

Controls & Jacks (9)

  • FREQUENCY— Controls the cutoff frequency of the filter in selected mode
  • ATTEN— Attenuator for CV input amount
  • VOLUME— Master output volume control
  • RESO— Emphasizes harmonics around the cutoff frequency, can induce self-oscillation
  • OUT— Filtered audio output
  • HP IN— Audio input routed to the high-pass filter
  • LP IN— Audio input routed to the low-pass filter
  • BP IN— Audio input routed to the band-pass filter
  • CV IN— Voltage control input for filter frequency
