Be Inspired By The Make Noise Echophon Pitch Shifting Echo Module

Pitch Shifting Echo with smooth Time Modulation, Tempo Sync, saturating Feedback and a unique Pitch Shifting algorithm inspired by the Springer Tempophon and lovingly engineered by DSP Guru Tom Erbe of soundhack. "...the most inspiring module of the year." -Electronic Musician.

  • Shift Pitch of signal +/- 2 Octaves
  • Exponential control of delay time -Maximum Time 1.7 Seconds, Minimum Time 7 ms
  • Tempo input allows synchronization of Echoes to multiple or division of an external Clock
  • Two independent internal digital Feedback paths (Loop 1 and Loop 2)
  • External Analog Feedback Path for filtered or processed echoes
  • FREEZE button/ gate input allows for hold, stutter, and sampling techniques
  • 24 bit ADC/DAC, 32bit processing, 16bit delay storage operating at 40khz
  • Vactrol based Mix circuit for smooth blending of dry and wet signals
  • All Analog Dry Signal Path
  • Voltage Control over ALL parameters
  • Pairs well with the Phonogene


Audio Input/Output

  • Signal Input: AC coupled, expects standard signal level of 10Vpp signal.
  • Level Control for Signal Input: overloads at 3:00 to 5:00.
  • Mix CV Input: unipolar control input. Range 0V to +5V.
  • Mix Combo Pot: blends between Dry (un-processed) signal & Wet (processed) Signal. With nothing patched to Mix CV Input, works as standard panel control. With Signal Patched to Mix CV Input, works as attenuator for that signal.
  • Mix Output: 10Vpp (depending upon Level setting and source material), AC coupled.

External Feedback

  • Feedback Input: AC coupled return for external FB loop. Expects standard signal level of 10Vpp.
  • Feedback Output: AC coupled, 10Vpp send for external FB loop.

Pitch Shift

  • Temphonic LEDs: indicate mechanics of the pitch-shifting machine.
  • Pitch Panel Control: bipolar panel control. At 12:00 no pitch shift, greater than 12:00 shifts pitch Up and less than 12:00 shifts pitch Down. Range is always dependent upon Depth setting.
  • Pitch Trim (Calibration Use Only)
  • Depth Panel Control: unipolar panel control that sets the index of the pitch shift, ranging from sub-microtonal chorusing to 4 octaves harmonizing.
  • Pitch 1 CV Attenuverter: bipolar attenuator for Pitch 1 CV Input.
  • Depth CV Attenuator: unipolar attenuator for Depth CV Input.
  • Depth CV Input: unipolar control signal input. Range 0V to +5V.
  • Pitch 1 CV Input: bipolar control signal input. Range +/- 4V.
  • Pitch 2 CV Input: bi-polar control signal input. Range +/- 2V for total of 4 octave range. Set Pitch Panel Control to full CCW for uni-polar control such as analog sequencer, or to 12:00 for bi-polar control signal such as CV Keyboard.


  • Echo Time LED: Indicates Tempo of the Echo Clock.
  • Echo Clock Output: outputs the Echo Time as 4ms wide clock pulse. 0V-5Vpp
  • Echo Time Panel Control: sets time/ length of Echo, from 7ms to 1.7 sec
  • Echo Time CV Attenuator: unipolar attenuator for Echo Time CV Input.
  • Echo Time CV Input: unipolar control signal input. Range 0V to +8V.
  • Tempo Input: allows synchronization of Echoes to multiple or division of an external Clock. While following external Tempo the Echo Time Controls will Multiply or Divide the incoming clock. Requires Clock/Gate signal amplitude of at least 1.5V and width of at least 6ms.

Internal Feedback Loops

  • Feedback CV Input: bipolar control signal input. +/- 8V.
  • Feedback CV Input Attenuverter: bi-polar attenuator for Feedback CV Input.
  • Feedback Panel Control: bipolar panel control that determines the amount and direction of feedback. At 12:00, there is no feedback. Turning CCW from 12:00 to 7:00 sends increasing amounts of feedback to the loop around the Pitch Shifter. Turning from 12:00 to 5:00 sends increasing amounts of feed back to the loop around the Echo.


  • Freeze Button: toggles Freeze on/ o. When Freeze is On, all sound in the Echo chamber is held until Freeze is turned Off
  • Freeze Gate Input: Freezes on Gate High. 1.5V trigger signal to operate.
  • Freeze LED: indicates status of the Echo chamber. Lights when Freeze is activated.


  • Width: 20hp
  • Max Depth: 30mm


  • 70mA@ +12V, 40mA @ -12V
