The projects on this page are a sampling of some of the collaborative work that has come out of the CMC in the last decades.

Students and staff at the CMC are constantly creating new music and artworks, putting on concerts and shows, releasing recordings and software, etc. For up to the minute info on CMC community activities, please see the News & Events on our front page and links to individuals’ websites on our CMC People page.


Chiplotle: Now that’s a spicy plotter library!

Finally, a way to control your grungy old pen plotters with your shiny new laptop! Chiplotle is a Python library that implements and extends the HPGL (Hewlett-Packard Graphics Language) plotter control language. It supports all the standard HPGL commands as well as our own more complex drawing commands. Chiplotle also provides direct control of your HPGL-aware hardware via a standard usb< ->serial port interface. Chiplotle is developed by Douglas Repetto, Victor Adán.


RTcmix is a real-time software “language” for doing digital sound synthesis and signal-processing. It is written in C/C++, and is distributed open-source, free of charge. In certain respects, it is similar in function to other extant unit-generator-based software languages such as CSOUND, SuperCollider and (to a lesser extent) JSyn and Max/MSP — they do share a common heritage, after all. There are some differences, however, between all these languages… and variety is of course the spice of life! RTcmix is developed in part by Brad Garton and Dave Topper.


MEAPsoft is a program for automatically segmenting and rearranging music audio recordings. It is aimed at musicians and experimenters who want to play with new ways to put audio fragments together using state of the art machine listening and analysis techniques. MEAPsoft was a collaborative project between CMC students and staff and Dan Ellis’s LabROSA and was supported by several NSF grants.


SPEAR is an application for audio analysis, editing and synthesis. The analysis procedure (which is based on the traditional McAulay-Quatieri technique) attempts to represent a sound with many individual sinusoidal tracks (partials), each corresponding to a single sinusoidal wave with time varying frequency and amplitude. SPEAR was written by Michael Klingbeil while he was a DMA student at Columbia.


PeRColate is a collection of synthesis, signal processing, and image processing objects (with source-code toolkit) for Max, MSP, and Nato, developed by Dan Trueman and R. Luke DuBois.


ArtBots: The Robot Talent Show

ArtBots is a series of international exhibitions featuring robotic art and art-making robotis. It was founded and is co-curated by Douglas Repetto.

Education & Service

Music and Computers: A Theoretical and Historical Approach

Growing out of classes in computer music at Dartmouth College in the early 1990s, the text Music and Computers was begun by Larry Polansky and Douglas Repetto in 1997 as part of an NSF Math Across the Curriculum (MATC) grant at Dartmouth College. Dan Rockmore, Mary Roberts, and Phil Burk joined as co-authors in 1998, and together we self-published the book online as a freely available resource, and for use in classes co-taught by Polansky and Rockmore. In 2002 Key College Publishing purchased the rights to this web-book, and Music and Computers was only available as a commercial website for several years. In 2008 Key College Publishing returned the rights to the book to the authors, and we have decided to once again make it a freely available resource.

We have reorganized and updated some minor aspects of the book for this current version. We hope it is useful and interesting.

J.P. Morgan Kids Digital Dance and Sound Project

The CMC brings music technology to children and their teachers. A collaborative project of Ballet Frankfurt, Lego, mak.frankfurt, Paul Kaiser, and the CMC. Sponsored by J.P. Morgan. Participation of local school children organized with the collaboration of the Creative Arts Laboratory of Columbia University’s Teachers College and its city wide artists-in-residence program for schools.


An experimental “interdisciplinary course in the digital arts” offered for several semesters by the CMC in collaboration with Columbia’s Visual Arts Division.


An experimental course offered by the CMC in collaboration with Columbia’s Visual Arts Division and Barnard’s Department of Dance.

Sonic Glossary

The Sonic Glossary is an innovative teaching tool for music appreciation. This project was initiated by Columbia Musicologist Ian Bent, with research by faculty and graduate students from the Department of Music and technical assistance from AcIS and the CMC.

Digitization Projects

During the past several years, the CMC has put its combination of well-maintained equipment (analog and digital) and well-trained personnel to good use in doing archive and preservation work. The CMC has successfully completed a number of archive projects, earning a well-deserved reputation as one of the few places available with both the correct equipment and trained expertise to do critical archival work. Current and recently completed archive and preservation projects include: Composer’s Forum Concert Archive; Columbia University Music Department Concert Archive; Cornell University Concert Archive; European Archive of Spoken Yiddish; Columbia University EMC Tape Archive.
