Why is Maths considered essential?

It does many things — envelopes, LFOs, slew limiting, mixing, logic — in ways that encourage patching creativity. Many consider it foundational to any modular system.

Maths has a learning curve. The "Maths Illustrated Supplement" document (free from Make Noise) teaches 32 patches that demonstrate its range.

Can it work as an oscillator?

At high speeds, channel 4 can reach audio rates — not a primary oscillator but usable for FM and experimental sounds.

The Make Noise Maths is the Swiss Army knife of Eurorack — a dual-channel analog function generator that handles envelopes, LFOs, slew limiting, mixing, signal logic, and much more. It's often the first module recommended after a voice and filter, and for good reason.

Two Channels, Endless Functions

Each channel features variable rise and fall times with independent attenuverters for CV control. Channel 1 emphasizes logarithmic response (snappy envelopes, percussive shapes). Channel 4 emphasizes exponential response (smooth swells, gradual ramps). As envelope generators, they produce attack-decay shapes triggered by gate inputs. As LFOs, they cycle continuously at rates from glacial to audio. As slew limiters, they smooth stepped voltages into glides and portamento.

Analog Computing

The center section is where Maths becomes more than the sum of its parts. The Sum output adds channels 1 and 4 together. The Inverter flips polarity. The OR output passes whichever channel has the higher voltage — a maximum function useful for combining triggers or creating complex waveshapes. Attenuverters on inputs 2 and 3 provide additional mixing and offset capabilities. Channel unity outputs allow normalled signal flow without cables.

Feedback and Self-Patching

Patching feedback from outputs to inputs unlocks advanced behaviors that transcend simple utility. Cycling envelopes fed back through attenuverters become complex LFOs with waveshaping. The end-of-cycle gate outputs trigger the other channel for ping-pong envelopes and cascading events. Make Noise's "Maths Illustrated Supplement" PDF teaches 32 patches covering everything from basic envelopes to envelope-following, clock division, and rudimentary sequencing.
