Get The Prescription For What You're Missing With The Steady State Fate Detect-Rx Eurorack Module

The Detect-Rx is a versatile envelope follower, voltage controlled comparator (gate extractor) and rectifier providing many useful prescriptions to fill in your modular needs.


  • DETECT-R is the main input and provides an envelope output, rectified output and gate output simultaneously. If a second signal is also patched into the EXTRACT-R, it can be used separately.
  • The top two controls and switch alter the response of the resultant envelope. Any signal level from LINE (-10dBv) up to modular (+/-5 to +/-10V) may be used.
  • The FREQ switch selects the spectra in which the envelope will respond to dynamic changes from the input signal. 
  • SMOOTH adds an additional ripple smoothing level control and tracks the FREQ setting
  • ENV GAIN controls the level of the envelope and is capable of attenuation as well as a lot of gain for low level input signals and even guitars (some pre-gain may be required for certain guitar pickups)
  • THRU provides a buffered copy of the input signal for easy patching of classic envelope follower applications and more
  • An LED is provided for visual feedback of the envelope and peak level (clipping) indication.


  • EXTRACT-R is a voltage controlled comparator with three threshold selections; LINE level, 5V and 10V peak for various levels of control and response. The output gate is normalized into the DETECT-R input by default - providing a second method of producing an envelope from a gate rather than dynamic content.
  • RANGE selects the maximum threshold level of the attenuator.
  • THR CV is the input for dynamic voltage control of threshold.
  • THRESHOLD works as the manual adjustment and as a CV attenuator when CV is utilized.
  • An RGB LED is provided for visual feedback of the threshold range and gate activity.

RECTIFIER (RECT) inverts negative voltages while leaving any positive signal unchanged.

Some uses for the DETECT-R:

  • Create envelopes that follow the input amplitude and frequency spectra
  • Slew audio or control voltages
  • Create a side chain envelopes for amplitude dynamics

Some uses for the EXTRACT-R:

  • Convert any signal into a gate or trigger
  • Create a delayed gate or trigger from a sloped waveform 
  • Create variable pulse waveforms -PWM
  • Convert audio into a series of pulses for insane distortion
  • Convert audio into pulses to modulate other parameters

Some uses for the RECTIFIER:

  • Convert bipolar signals into uni-polar positive signals
  • Intense second harmonic distortion of audio
  • Frequency doubling of bipolar signals in general
