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
