• Congratuations! - Unpacking
Congratulations!
We thank you for choosing eo•body, the essential link between the world of analogue sensors and the digital world of computer processing. The idea of this joint development between Ircam & eowave was to offer the most easy-to-use analogue to MIDI interface for an
affordable price. Of course, other analogue to MIDI converters have already been developped in the past, but none have ever linked simplicity to quality and price like eo•body does.
And indeed, the use of such tools has often been limited or been specially designed for big
projects because of the high cost such installations usually require. eo•body interface is
based on the analogue to MIDI converter Atomic Pro which has been developped by
Emmanuel Flety Ph.D. & engineer at Ircam. With this high-end embedded technology,
eo•body offers high quality data processing, including subsampling and internal filtering
capabilities.

Who’s Who
Ircam
Ircam was founded as a place that combines scientific research, development of related
technologies and contemporary musical creation, for the benefit of the musical and scientific communities. One of the main goals is to contribute, through science and technology, to
the renewal of musical expression. Reciprocally, specific problems related to contemporary
creativity have lead to original steps in the scientific field, with theoretical, methodological
and applied aspects. One of the main links between research and the musical production
activities is done through the development of software environments for composition, that
integrate models and prototypes which come from research teams working in various fields
related to music: computer science (languages, human-computer interface, realtime, database management), digital signal processing, acoustics, psycho-acoustics and cognitive
psychology of audition. Knowledge and tools are also applied to fields of activity in the
industry that go far beyond contemporary musical production.
« At Ircam, my work is mainly oriented towards the design of electronic hardware for stage
and live performance applications. The aim of this design is to provide composer sand performers new tools for expression and control in order to communicate with the computers
involved in computer assisted compositions and musical piece interpretation (sound processing, sound synthesis, sample triggering, spactialization…).
One of those tools is AtoMIC Pro (Analogue to MIDI Converter). This device digitizes analogue signals from sensors to transmit them to the computer which might use those information as a «vision» of the outer world, so our five senses do. Thus stimulated, the machine can «answer» and take certain decisions depending on what happens on stage. This tool
is very useful in the field of interactive sound and/or video installations where it is possibly
needed, for instance, to detect a person at the key place in order to trigger a sound sample,
or to measure the activity in a room to control the volume of a sound effect. »
Emmanuel Fléty, Ircam.
eowave
« eowave was founded in 2002. Since 1998, we have designed our first products under the
name of More Electronic Sounds. We have started with the development of software and
stepped on hardware design of analogue machines and midi tools. There is not such a big
gap between developing software and hardware: both are a subjective representation of the
definition of the sound process. I really enjoyed developing iSynth. With the Essential
Instruments from Cycling’74’s Pluggo 3, each module is dedicated to a special synthesis:
granular, additive synthesis, FM, an analogue modeling synth or a wavetable synth… I have
tried to extract the essential of synthesis, starting all over again with fundamental questions:
«what’s an FM synthesis & how should it be concretized?» Now, some analogue effects I
have designed - the little analogue effects called the «bugs» for example - can be viewed as
some kinds of hardware Essential Instruments. Several little boxes, each representing an
effect, a multimodal filter, a ring modulator, a phaser or a sequencer. Several little boxes any
musician can use to add an analogue feeling to his music… Several easy-to-use little boxes
which can be used alone or assembled to create new sounds. But aside the search for new
tools, and new ways of expression is a real quest among unknown dimensions. The world
of synthesis is immense, while the world of expression has no limits. At this frontier comes
eo•body, an ideal intermediate between the external audio and video environment and the
artist, the essentiel bridge linking the world of analogue sensors to the world of digital process. »

I - Sensors
& new ways of expression
From the Idea…
Men have always dreamt of new ways of communication. Through ages, men have thought
of their body as a tool of communication. And indeed, when communicating, this is not only
your voice, nor the only expression in your face that transmits a message, but your entire
way of being. This is your entire body which projects you inside the individual world of one
another. In all cultures, men have developped new ways of communication through dance,
music, art. And still in a matter of a better communication, men have always worked to
improve the interaction between men and machines, thus since the very beginning of
mechanics and later, electronics. More and more, the body has become the cornerstone of
interactive systems of communication. New technologies widen the range of controls. And
controls have entered everyday’s life without us noticing. Remote controls are everywhere:
we control TV, we control VCRs, DVDs, stereos, ovens, climates, windows, garage doors…
Control surfaces are everywhere. Faced to art, control appears to be the new way of expression of this early millenium. Many artists are looking for new ways of expression, of conceptualizing ideas… In this perspective, sensors open new dimensions of expression. eo•body
is the key link between the world of analogue sensors and digital systems.
…To the Realization
The need of new technologies to control the sound has increased with the development of
interactive sound installations and interpretation of musical pieces requiring interfaces other
than traditional instruments. eo•body is the intermediate you need to connect sensors of
any kind (faders, mechanical pressure sensors, piezo electric sensors, infrared barriers,
intruder detector/passive IR sensors, temperature sensors, etc.) to a musical MIDI environment (sequencer, computer, sampler…). eo•body does not impose the sensor type and features portability and versatility. It can be used for sound synthesis control with the jMax environment (Real time team), PD or Max/MSP. As another example, eo•body can also be used
for the control of a MIDI/digital audio sequencer with an original and completely new user
interface.
The MIDI digital code allows to transmit many different data sources. It is known for the
transmission of music notes but other sources such as light, pressure, temperature, speed
or electromagnetic field can be transcoded via MIDI. Considering this, the field of applications of MIDI becomes much wider… All you need is a powerful analogue to MIDI converter
like eo•body and sensors of your choice. As a sensors to MIDI interface meaning to simplify the design of new gestural controllers or interactive sensor-based sound installations,
eo•body converts analogue signals generated by sensors to MIDI messages which will be
received by a sound generator and used to control parameters such as volume, panoramic,
reverberation… The MIDI messages coding the gestures act directly on the sound, turning
the whole system into a new kind of musical instrument. eo•body will transmit the sensors
signal to the computer under digital form, through the MIDI standard. eo•body is fully compatible with any kind of devices featuring a MIDI interface (MIDI port) and makes a real bridge between the analogue world of sensors and digital audio control by gestures. Don’t limit
yourself: eo•body can convert to MIDI up to 16 sensors!
