Make Noise Maths
An analog electronic signal processor and complex function generator in Eurorack format.
Overview
The Make Noise Maths is an analog signal processor and generator for the Eurorack modular synthesizer system. Make Noise markets it as a "complex function generator," and it is sometimes called an "analog computer." It generates and shapes control voltages and audio signals. A 2013 version exists with documented differences from earlier revisions, including updated power requirements. Some users report that the original versions were built with higher precision and better materials. One of its more advanced functions is the OR output, which combines four channels and delivers the highest voltage among the four inputs.

Design
Maths has been called 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
According to Equipboard, 39 professional artists use the Maths. Beginner tutorials exist too, so it gets used for both advanced and educational modular work. Forum discussions point out specific behaviors, such as the OR output delivering the highest voltage across four channels. Some users say the original version was built with greater precision and superior materials compared to later versions or clones.
Market
Used units have sold for $250 in excellent condition. New retail prices range from $265 to $322, depending on finish and retailer. Thomann lists the "Black & Gold" variant at $322. Some sellers include both grayscale and original panels with the module.
