Noise Engineering Sinc Legio

Compact stereo oscillator with wavemorphing, folding, and PM in 6HP

6 HP Eurorack module

Sinc Legio is a compact stereo oscillator with three synthesis algorithms that cover a wide timbral range. Warp mode uses internal PM with a summed modulator for bright, heavily modulated sounds. Op mode is designed for multi-operator PM patches with external oscillators or self-modulation. Fold mode uses the Noise Engineering infinifolder for complex wavefolding timbres. A vintage-inspired stereo chorus can be applied to any algorithm. Hard-sync and stereo PM inputs make it equally powerful as a standalone voice or as an operator in a larger PM array. Part of the Legio platform — firmware can be swapped to any other Legio firmware for free via USB.

Features

  • Three switchable synthesis algorithms: Warp (PM + summed modulator), Op (configurable PM operator), Fold (infinifolder wavefolding)
  • Stereo audio outputs with vintage-inspired chorus in three settings (off, moderate, heavy)
  • Morph control continuously changes the oscillator waveform across all algorithms
  • Timbre control behavior changes per algorithm: modulation pitch (Warp), PM index (Op), fold amount (Fold)
  • Hard-sync input for classic sync timbres with external oscillators
  • Stereo phase-modulation inputs (PM L normals to PM R) for complex harmonic patches
  • Pitch encoder with press-and-turn for coarse semitone steps and fine-tune mode
  • 1V/octave calibrated pitch CV input with -2V to +5V range
  • CV inputs for Morph and Timbre parameters (0V to +5V)
  • Autocalibration on boot when nothing is patched to Pitch CV
  • Part of the Legio platform — free firmware swapping via USB to any Legio firmware
  • Audio output up to 16V peak-to-peak

Controls & Jacks (13)

  • Pitch— Sets the pitch of the oscillator. Turn for fine tuning, press and turn for coarse tuning. Calibrated for 1V/octave tracking.
  • Morph— Changes the waveform of the oscillator. Continuously morphs through available waveshapes.
  • Timbre— Changes the timbre of the oscillator. Behavior depends on the selected algorithm: modulation pitch in Warp, PM index in Op, or fold amount i
  • Warp/Op/Fold— Three-position switch that selects the oscillator algorithm. Warp: PM with summed modulator. Op: configurable PM operator. Fold: wavefolding
  • Chorus— Three-position switch for the vintage-inspired stereo chorus effect. 0 is off, I is moderate, II is heavy.
  • Sync In— Hard-sync input. Responds to a rising edge around +1.6V. Resets the oscillator phase on each trigger for classic hard-sync timbres.
  • Pitch CV In— 1V/octave calibrated pitch CV input. Range: -2V to +5V. Autocalibrates on boot with nothing patched.
  • Timbre CV In— CV modulation input for Timbre parameter. Range: 0V to +5V.
  • Morph CV In— CV modulation input for Morph parameter. Range: 0V to +5V.
  • PM L In— Left phase-modulation input for audio-rate signals. AC coupled. Patching here normals to the right channel. Use for complex harmonic PM patc
  • Out L— Left audio output. Up to 16V peak-to-peak.
  • PM R In— Right phase-modulation input for audio-rate signals. AC coupled. Can be used independently from PM L for stereo PM experiments.
  • Out R— Right audio output. Up to 16V peak-to-peak.
