PoliMATHS
Eight-channel CV and audio event generator for the New Universal Synthesizer System or any Eurorack modular synthesizer. Uses a single set of controls to generate complex functions at eight independent channel outputs, combining Rise-Fall envelopes with variable Curve and a variable-Shape Oscillation whose amplitude is controlled by the envelopes.798
Capabilities 3
- Envelope Generatorenvelope-generator
- Eight-channel Rise-Fall envelope generator with variable Curve; all eight channels share a single set of controls with Spread and Modulation Dissemination for per-channel variation.798
- LFOlfo
- Each channel includes a variable-Shape oscillator (saw/triangle/ramp) that can operate at LFO rates with depth controlled by the Rise-Fall envelope, modulated per-channel via Spread or Modulation Dissemination.798
- Voltage-Controlled Oscillatorvco
- Oscillator can run at audio frequency with 1V/oct pitch tracking via Rate CV input (attenuverter fully CW), enabling eight-channel polyphonic audio generation.798

Parameters 16
| Name | Type | Range | Behavior |
|---|---|---|---|
| Curve | knob | — | Sets the curve of activated functions from logarithmic to linear to exponential. Unlike MATHS/FUNCTION/0-COAST, it has been tailored for multi-channel use with Spread and Modulation Dissemination. The CV input is a traditional live modulation input unaffected by Spread.798 |
| Cycle Button | button | — | 798 |
| Fall | knob | — | Sets the time for the function to travel back down to minimum voltage after Rise completes. More clockwise = longer fall time. Can be modulated via Spread or Modulation Dissemination.798 |
| Fall attenuverter | knob | — | 798 |
| Mode Button | button | — | 798 |
| Osc | knob | — | Sets the depth of oscillation superimposed on activated functions. At full CCW only the function appears; at full CW full-scale oscillation is present enveloped by the function. Can be modulated via Spread or Modulation Dissemination.798 |
| Rate | knob | — | Sets the rate/frequency of oscillation from slowest (CCW) to fastest (CW). When attenuverter is fully CW and CV is patched for Modulation Dissemination, tracks 1 V/oct. Can be modulated via Spread or Modulation Dissemination.798 |
| Rate Attenuverter | knob | — | 798 |
| Rise | knob | — | Sets the time for the function to travel up to maximum voltage. More clockwise = longer rise time. Shorter rise times produce percussive functions; longer ones create breathing/swelling effects. Can be modulated via Spread or Modulation Dissemination.798 |
| Rise attenuverter | knob | — | 798 |
| Shape | knob | — | Determines the shape of the oscillation: falling saw at CCW, triangle at 12:00, rising ramp at CW. Using CV beyond the knob range produces other waveforms including noise. The Shape CV Input is a traditional live modulation input unaffected by Spread.798 Zones
|
| Span | knob | — | Sets the Channel Span for Activation according to current Span Mode. In Channel Index mode, selects which of the 8 channels is active; at 12:00 selects no channel, left selects channels 8-1, right selects channels 1-8. In Round mode sets step size. In Parallel mode sets clock division spread.798 |
| Span CV Input attenuverter | knob | — | 798 |
| Spread Combo Pot | knob | — | Bipolar combo pot. Sets direction and amount of Spread modulation sent to unpatched Spreadable parameters weighted per channel. When Spread CV Input is patched, operates as a bipolar attenuator for that CV.798 |
| Strength | knob | -9V – 9V | Bipolar control setting overall amplitude and polarity of function and/or oscillation output. CCW: negative polarity (0 to -9VDC). At noon: 0VDC (no activity). CW: positive polarity (0 to +9VDC). Can be modulated via Spread or Modulation Dissemination.798 |
| Strength Attenuverter | knob | — | 798 |
