Using Control Structures to Embed Complex Mapping Tools into Ableton Live

This paper presents Mapper4Live, a software plugin made for the popular digital audio workstation software Ableton Live. Mapper4Live exposes Ableton’s synthesis and effect parameters on the distributed libmapper signal mapping network, providing new opportunities for interaction between software and hardware synths, audio effects, and controllers. The plugin’s uses and relevance in research, music production and musical performance settings are explored, detailing the development journey and ideas for future work on the project.

Mapping Tools Virtual Workshop 2021

On 2 September 2021 we held the second annual workshop on the mapping tools project (libmapper and the surrounding tools). This year we had presentations and discussions covering:

  • recent related projects and publications
  • map expression syntax for supporting reducing over vectors, signal history, signal instances, and inputs to convergent maps.
  • improving distribution via package managers
  • using libmapper on embedded platforms including ESP32, Raspberry Pi, and Bela
  • integration with the game engines Godot and Unity
  • using MediaPipe as a libmapper source device
  • implications of the upcoming MIDI 2.0 protocol for interfacing with commercial hardware and software
  • proposals for future applications

Video documentation of the workshop will be posted soon!

Workshop on the T-Stick @CIRMMT

The T-Stick DMI

Composer/instrumentalist D. Andrew Stewart performing the soprano T-Stick.

On Saturday November 16, 2019, CIRMMT hosted a workshop on the T-Stick digital musical instrument. The workshop included presentations by myself, composer D. Andrew Stewart (the other originator of the T-Stick), Eduardo Meneses, Takuto Fukuda, Mathias Bredholt, and Mathias Kirkegaard. Presentations covered the history, design, and development of the instrument; mapping and performance practice; and current advances including embedding libmapper and algorithms for high-level gestural descriptors in the instrument firmware and the addition of programmable force-feedback hardware to the physical structure of the DMI.

The workshop also served to launch the 2019 T-Stick Creation Project, a new  program supporting composition for the T-Stick which will culminate in a concert performance in February 2020.

This workshop explores the development of compositional and performance practices for the T-Sticks—a family of gestural musical controllers designed to sense performer interactions such as touching, tapping, twisting, tilting, squeezing, and shaking. Joseph Malloch—the T-Stick designer (Dalhousie University)—and D. Andrew Stewart—composer/T-Stick instrumentalist (University of Lethbridge)—will discuss the instrument design and compositional possibilities for the T-Sticks, followed by a hands-on workshop for the practical use of the T-Stick, including how to set up, perform and notate. Finally, the workshop will include a report on the CIRMMT Student Award project, Between design, composition, and performance: expanding and embedding a high-level gesture vocabulary for the T-Stick, by Eduardo Meneses and Takuto Fukuda.

MINT – Music in New Technologies Forum


The MINT Forum 2018 is devoted to the advancement of music through new technologies. How can advances in new technologies change the experience of making music (from the musician’s perspective) and listening to music (from the audience’s perspective)? What are the musical and performative implications and applications of the vast array of new technologies that are now emerging?

WHERE: University of Kings College, Halifax, NS
WHEN: 16–18 November, 2018
