Practical information


Modalys is an environment that lets the user create completely novel virtual instruments based on “simple” physical objects such as strings, plate, tubes, membranes, plectrum, bows, or hammers, and making them interact.

It is also possible to build objects with complex forms using a 3D mesh. Modalys brings these objects to life by calculating their sonic vibrations.

By combining different physical, resonating objects and by specifying the type of interaction (striking, rubbing, using a mouthpiece or a bow, etc.), the user creates a virtual instrument and then decides how it will be played and controlled. Max and OpenMusic communicate directly with the Modalys synthesis engine via intuitive graphical interfaces


Upon completion of this course participants will be able to construct a simple virtual instrument and interact with it in the ModaLisp environment and in real-time with Max.


Composers, musicians, sound designer, teachers


Mastery of the Macintosh environment (OS X), a sequencer software program such as Pro Tools, LogicAudio, and a sound editor like Audacity.

Educational Resources and Techniques

Classroom equipped with computers with all the necessary software installed, headphones, and MIDI keyboards

Class Format: Training alternates between presentations, explanations on theory and hands-on exercises

Didactic Materials: Video-projected presentations

Supervision and Assessment

Welcome the first day of training beginning at 9:45am

Attendance controlled; signature of an attendance sheet required every morning and afternoon

Assessment of acquired knowledge using a multiple-choice test (30 minutes) taken at the end of training

A certificate at the end of the program is given to each participant with the results of the exam

Training Period and Organization

18 hours of training. Wednesday-Friday, January 19-21, 2022. 10am-1pm/2:30pm-5:30pm

11 students maximum

This training program will be held at IRCAM on-site in accordance with local sanitary guidelines and measures in place at the current time. These guidelines and measures may change. In the event that IRCAM cannot physically welcome students, an adapted program will be held virtually. For further information, please contact: info-pedagogie[at]


During this class, participants will explore all the Modalys interfaces. Participants take their first steps using the ModaLisp interface and then in Max to play virtual instruments in real-time. They also learn how to build instruments and calculate sounds using OpenMusic
