Make Noise Mimeophon

Stereo color repeater from microsound to infinity

16 HP Eurorack module

The Mimeophon is a stereo multi-zone color audio repeater by Make Noise and soundhack, coded by Tom Erbe. It morphs continuously between Karplus-Strong synthesis, flange, chorus, echo, and looping across eight color-coded zones spanning microsound to 41-second phrase loops. Its character is rich and alive, coloring repeats with spectral transformations from dark oil-can warmth to crispy digital shimmer while spatializing them in stereo space.

Features

  • Full stereo in and out with L input normalled to R for mono use
  • Eight color-coded zones spanning 1.3ms to 41.796s repeat lengths
  • Zones are nested — incoming audio writes to ALL zones simultaneously
  • Continuous Rate parameter with doppler pitch shifting on modulation
  • Doppler-free tempo sync via TEMPO input with slew-less crossfade
  • TEMPO input usable as tap tempo by patching a gate and tapping twice
  • Rate multiples and divisions from x2 to /2 across 13 steps when clocked
  • Skew mode creates independent left/right repeat rates from single Rate control
  • Ping Pong mode bounces repeats between left and right channels
  • Swap mode swaps left/right feedback paths when Skew is active
  • HOLD button for non-destructive infinite loop manipulation
  • FLIP button for reverse playback in medium/large zones

Controls & Jacks (29)

  • L Input— Signal input for Left Channel. Modular signal level (typically 10Vpp).
  • R Input— Signal input for Right Channel. Modular signal level (typically 10Vpp). Normalled to L Input.
  • Mix— Sets mix between Live Signal and Repeats. Works as attenuator when Mix CV is patched.
  • L Output— Signal output for Left Channel. Modular signal level (typically 10Vpp).
  • R Output— Signal output for Right Channel. Modular signal level (typically 10Vpp).
  • Mix CV— CV input for Mix. Range 0-8V. Normalled to 8V.
  • Repeats CV— CV Input for Repeats. Range 0-8VDC.
  • Halo CV— CV Input for Halo. Range 0-8VDC.
  • Repeats— Sets number of Repeats from 1 to infinity. When HOLD is engaged, sets Repeats start point.
  • Rate CV— CV input for Rate. Range 0-8VDC.
  • Rate CV Attenuverter— Bipolar input attenuverter for Rate CV Input.
  • Halo— Sets Halo amount, smearing Repeats in stereo space.
  • Zone— Selects Zone. Current Zone indicated by Zone Window.
  • Rate— Sets frequency of Repeats in current Zone. When Skew is on, Rate controls Left and Right Repeat frequency in opposite directions.
  • Color— Adjusts Color to focus feedback energy for timbral shifts. Unity at ~3:00 position.
  • Zone CV Attenuverter— Bipolar CV input attenuator for Zone CV Input.
  • Zone CV— CV control over Zone Selection. Range 0-8VDC.
  • microRate— Un-attenuated doppler modulation destination. Tracks 1v/oct in Zone 0. Range +/-3V. Unity Gain.
  • Color CV Attenuverter— Bipolar input attenuator for Color CV Input.
  • FLIP Input— Expects Gate of 2.5V or greater. Toggles FLIP on and off.
  • HOLD Input— Expects Gate of 2.5V or greater. Toggles HOLD on and off.
  • TEMPO Input— Expects regular clock pulse of 2.5V or greater. When in use, RATE will synchronize to divisions/multiples of the Tempo.
  • RATE Output— Trigger output containing an OR of both channels' rates, 0V or 8VDC.
  • FLIP— Press to Flip Repeats so they are heard in reverse.
  • HOLD— Press to HOLD Repeats indefinitely and non-destructively. When HOLD is engaged, Repeats control sets Repeat start point.
  • SKEW— Press to skew Left and Right repeat rates apart. Hold to engage Ping Pong (or Swap if already skewed). LED lights when Skew is active.
  • Color CV— CV Control over Color. Range 0-8VDC.
  • RATE Output LED— Flashes at the current Rate; flashes irregularly when Skew is active.
  • Zone Window— Color indicates currently selected Zone. Flashes when Ping Pong or Swap is engaged.
