Make Noise Maths

An analog electronic signal processor and complex function generator in Eurorack format.

Overview

The Make Noise Maths is an analog electronic signal processor and generator designed for the Eurorack modular synthesizer system. Marketed as a "complex function generator" and sometimes described as an "analog computer," it serves as a multifunctional tool for generating and shaping control voltages and audio signals. A 2013 version exists with documented differences from earlier revisions, including updated power requirements. Some users report that original versions were built with higher precision and better materials. The module is known for advanced functions such as combining multiple channels via an OR output, which delivers the highest voltage among four inputs.

Design

The Make Noise Maths is described as an analog electronic signal processor/generator and has been referred to as an analog computer. It was influenced by Buchla’s Algebraic Processor designs, particularly the Model 257 and 281, which redefined control voltage use in synthesis. The 2013 revision introduced changes documented in an updated manual and discussed in official Make Noise video content.

Reception & Use

The Maths is used by 39 professional artists according to Equipboard, and beginner tutorials exist, indicating its role in both advanced and educational modular synthesis contexts. Forum discussions highlight specific behaviors, such as the OR output delivering the highest voltage across four channels. Some users distinguish the original version as being built with greater precision and superior materials compared to later versions or clones.

Market

Used units have sold for $250 in excellent condition, while new retail prices range from $265 to $322 depending on finish and retailer. The "Black & Gold" variant is listed at $322 by Thomann. Some sellers include both grayscale and original panels with the module.
