Happy Nerding Super Sawtor

Analog supersaw harmonics from any waveform input

6 HP Eurorack module

Super Sawtor is an analog Eurorack module that generates additional pitch-shifted harmonics from an incoming signal to produce supersaw-style unison waveforms, tuned to emulate the harmonic character of the Roland JP-8000/8080 supersaw oscillator. It works best with sawtooth, triangle, or sine wave inputs and creates a vivid, tension-filled unison effect distinct from phase-shifting sawtooth animators. The module contains two independent identical sub-modules in one panel, with the lower sub-module internally normalled to the upper for flexible dual-voice or stereo operation.

Features

  • Completely analog circuit with no digital aliasing
  • Supersaw harmonic spread tuned to emulate Roland JP-8000/8080 supersaw oscillator character
  • Creates additional pitch-shifted harmonics rather than phase-shifting like sawtooth animators
  • Two identical independent sub-modules in one panel (double Super Sawtor)
  • Lower sub-module IN and CV inputs are internally normalled to upper sub-module inputs
  • Normalling disconnected automatically when a cable is inserted into lower sub-module jacks
  • SPREAD knob sets harmonic detuning amount from 0 to 10
  • CV input for voltage-controlled modulation of spread amount
  • CV attenuator knob to scale CV input effect on spread
  • Bipolar CV modulation supported for spread increase and decrease
  • Internal spread value clamps at zero — no negative spread
  • Onboard trimmers (TP1) for input level calibration to non-standard signal levels

Controls & Jacks (12)

  • CV Amount— Attenuator for CV input signal to Spread control. Scale 0-10. Any signal applied to CV input is internally added to manual Spread amount.
  • OUT— Resulting processed waveform output. Output level averages -5V to +5V.
  • IN— Audio input to be processed. Any AC signal, preferably -5V to +5V (10V pk-pk) with rising slope. Square wave will not work.
  • Spread— Sets frequency spread of additional harmonics generated by the Super Sawtor. Scale 0-10. Increasing spread shifts harmonics further from cen
  • Mix— Sets frequency spread of additional harmonics for lower sub-module. Scale 0-10.
  • CV (Lower)— input jack
  • CV Amount (Lower)— Attenuator for CV input signal to Spread control on lower sub-module. Scale 0-10.
  • OUT (Lower)— Resulting processed waveform output for lower sub-module. Output level averages -5V to +5V.
  • IN (Upper)— Audio input to be processed. Any AC signal, preferably -5V to +5V (10V pk-pk) with rising slope. Square wave will not work.
  • CV (Upper)— Control voltage input for Spread modulation. Can be AC or DC. -5V to +5V input voltage range welcome. Bipolar CV allows spread change in bot
  • OUT (Upper)— Resulting processed waveform output. Output level averages -5V to +5V.
  • IN (Lower)— Audio input for lower sub-module. Any AC signal, preferably -5V to +5V (10V pk-pk) with rising slope. Internally connected to upper IN when
