What it is and what it was built for
MATHS is a 20hp Eurorack module built as an analog computer for musical use. It was designed to sculpt control signals — not produce sound — extending Don Buchla’s adaptation of analog computer circuits for music in the 1960s.
How it works, in terms a player would use
MATHS processes control voltages and digital timing signals using physical knobs and patch points. It integrates, scales, inverts, or amplifies incoming analog signals. It adds, subtracts, or ORs up to four signals. It generates linear, logarithmic, or exponential functions — triggered or free-running — with no input required. It converts gate/clock inputs to analog outputs and analog inputs to gate/clock outputs. It delays digital timing information.
What it does better than anything else
It handles bidirectional analog-digital conversion and digital delay of timing signals more flexibly than most Eurorack modules. Its autonomous function generation spans 2ms to 25 minutes per cycle — wider than typical LFOs or envelope generators. Its arithmetic and logic operations on up to four CVs are immediate, analog, and patchable without sequencing.
What it does badly
It does not generate audio-frequency waveforms. It cannot modulate pitch or timbre directly. It has no built-in quantisation, sample-and-hold, or voltage-controlled switching. It offers no visual feedback, no presets, and no memory.
What people made with it
The sources do not specify what people made with it.
Who should use it, and who should not
Use it if you patch modular systems daily and need deterministic, real-time manipulation of timing, slope, sign, and signal relationships. Avoid it if you work mostly with digital sequencers, need visual feedback, or rely on recallable settings.
Is it worth your time
Yes — if you need precise, hands-on control over signal timing, shape, and logic in a Eurorack system. No — if you expect it to generate audio tones, filter sound, or replace dedicated LFOs or envelope generators without patching.
