Reference excerpt

The Lemur was a highly customizable multi-touch device from French company JazzMutant founded by Yoann Gantch, Pascal Joguet, Guillaume Largillier and Julien Olivier in 2002, which served as a controller for musical devices such as synthesizers and mixing consoles, as well as for other media applications such as video performances. As an audio tool, the Lemur's role was equivalent to that of a MIDI controller in a MIDI studio setup, except that the Lemur used the Open Sound Control (OSC) protocol, a high-speed networking replacement for MIDI. The controller was especially well-suited for use with Reaktor and Max/MSP, tools for building custom software synthesizers.

Creating an interface The Lemur came with its own proprietary software called the JazzEditor to create interfaces. Users could build interfaces using a selection of 15 different objects (including fader, knobs, pads, sliders...), group them as modules and arrange them using as many pages as needed. Each object could then receive any MIDI or OSC attribute. A particularity of the Lemur was the ability to modify the physical behavior of each object (for instance adding or removing friction on faders). The internal memory of the Lemur enabled the storage of many interfaces, each one controlling a specific software for instance.

Discontinuation JazzMutant discontinued production of the Lemur in 2010, citing competition from more mainstream multi-touch capable computers and tablets. The multi-touch interface was recreated as an iOS, macOS and Android app by the software company Liine (founded by Richie Hawtin). In September 2022, Liine announced the discontinuation of the Lemur app.

Users The Lemur had been used by several famous artists.

Worked examples

Example 1 — a first encounter with Lemur (input device)

Start with the simplest possible case. Write down what Lemur (input device) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Lemur (input device) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Lemur (input device) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Lemur (input device)

In research: Lemur (input device) appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Lemur (input device) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Lemur (input device) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Experimental musical instruments, Music hardware, so understanding it makes those chapters shorter.
In everyday life: Look for Lemur (input device) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
