So what is GDIF? Gesture description interchange format
"The Gesture Description Interchange Format (GDIF) is being developed as a tool for streaming and storing data of music-related movements, actions, and gestures. Current general purpose formats developped within the motion capture industry and biomechanical community (e.g. C3D) focus mainly on describing low-level motion of body joints. We are more interested in describing gesture qualities, performer-instrument relationships, and movement-sound relationships in a coherent and consistent way. A common format will simplify working with different software, platforms and devices, and allow for sharing data between institutions." (The Jamoma environment is used to prototype GDIF.)
Alexander Refsum Jensenius is the man who initiated the GDIF project. He's written a variety of articles about music, gestures, movement, and emerging technologies.
Here's Alexander's bio: "Alexander (BA, MA, MSc, PhD) is a music researcher and research musician working in the fields of embodied music cognition and new interfaces for musical expression (NIME) at the University of Oslo and at the Norwegian Academy of Music. He studied informatics, mathematics, musicology, music performance and music technology at UiO, Chalmers, UC Berkeley and McGill. Alexander is active in the international computer music community through a number of collaborative projects, and as the initiator of GDIF. He performs on keyboard instruments and live electronics in various constellations, including the Oslo Laptop Orchestra (OLO)."

Sonic Interaction Design (SID)
"Sonic Interaction Design is the exploitation of sound as one of the principal channels conveying information, meaning, and aesthetic/emotional qualities in interactive contexts."
SID Action has four working groups:
- "SoundHack was my main thing for a long time, and I poured a lot of effort into it. It was the place I put my ideas. I did have something of a mission with SoundHack. I wanted to take some computer music techniques that were only used in academia, and get them out there so that all types of musicians could use them."-Tom Erbe SoundHack Spectral Shapers
Csound Blog "Old School Computer Music"
"Csound is a sound and music synthesis system, providing facilities for composition and performance over a wide range of platforms. It is not restricted to any style of music, having been used for many years in the creation of classical, pop, techno, ambient, experimental, and (of course) computer music, as well as music for film and television."-Csound on Sourceforge
Quote from Dr. Richard Boulanger (Father of CSound):
"For me, music is a medium through which the inner spiritual essence of all things is revealed and shared. Compositionally, I am interested in extending the voice of the traditional performer through technological means to produce a music which connects with the past, lives in the present and speaks to the future. Educationally, I am interested in helping students see technology as the most powerful instrument for the exploration, discovery, and realization of their essential musical nature - their inner voice."
Upcoming post about innovations at Stantum:
I'll be focusing on Stantum and its music and media technologies division, JazzMutant. in my next post. It is interesting to note that the co-founders of Stantum, Guilliam Largilleir and Pascal Joget, have a background in electronic music. Guiliam specializes in multi-modal user interfaces and human-machine interface technologies. Pascal has a background in physics and electronics, and has worked as a sound engineer.
My music back-story:
The very first computer-related course I took was Computer Music Technology (in 2003), since I play an electronic midi/digital keyboard and previously tried to teach myself a few things, long before computers and related technologies were "easy" for me to figure out. During the mid-90's, I tried my hand at Dr. Richard Boulanger's CSound, and tried to acquaint myself with tools from Cycling'74, but I gave up. Not long after that, bought the first version of MOTU's Freestyle, which nicely worked on my Performa 600, hooked up to my Ensoniq 32, after the nice people at MOTU sent me an update that was compatible with my set-up. Later on, I came across Tom Erbe's SoundHack freeware.
A lot has changed since then!
