Final Year Project Video Demonstration

For any one who wishes to know what Music Technology at Edinburgh actually means? well this is what i created for my final year project, a literal creative fusion of music technology and technology! Enjoy!

Max/Msp to Kinect Via OSC for Offical Microsoft SDK


Today I finished the very first stages of my 4th year research project which was finding a way to take data from the Xbox Kinect and send it to Max/Msp. By using the Ventuz OSC C# wrapper i was able to pack all the X, Y, Z data for all the skeletal points into an OSC bundle and send that to Max where it was unpacked in the patch.

The data sent from the Kinect is the unchanged co-ordinate system of values in metres rangeing from -1 to 1.

That being said the data sent from Kinect to Max can be used by any device that is capable of reading OSC packets .The format of the OSC message is

/joint/skeleton_[1/2]/[joint] x, y, z

This is a simple implementation allows quick and easy access to the full power of the kinects skeletal tracking in windows for users of the offical SDK over OSC. I hope it can be of some use.

Chaos Music - The Final Piece

Chaos music is a composition based on my research and programming of the functions documented in my previous post. The piece uses the output data from the chaotic functions to drive musical synthesis with the built in functions of CLM, more explanation about methodology can be found in the attached report.

Algorithmic Comp. Piece 2 Research - Choas Functions

For my final year piece iv been researching choatic functions and non-linear maps. Below is a selection of function iv ported into Lisp. Each function outputs a text file that can be imported into most graphing software (the corresponding pictures were all produced with MATLAB). I intend to implement these functions and use there output to drive a piece of music.

The Logistic Equation


(with-open-file (*standard-output* "logistic.txt" :direction :output
:if-exists :supersede)
(let* ((x 0.5)
(r-env '(0 1 1000 4.0))
(r 0.0))


(loop for i below 1000 do
(setf r (envelope-interp i r-env)
x (* r (* x (- 1 x))))
(format t "~D ~D~%" r x)
)))

Algorithmic Composition with Common Lisp Music - Piece 1

This composition was used as an inital exploration into the world of Lisp and Common Lisp Music 4 (CLM). It experiemtned with using the builtin instruments as well as instruments provided by the course lecturer. It takes loose inspiration from a piece by John Chowning with more explanation in the report. All samples used are referenced from within the source file and can be downloaded from www.freesound.org

Fourier Analysis and MATLAB - Phase Vocoder

My first go at using MATLAB as a language was to build a phase vocoder with variable Q (below 1.5 works best) and create a GUI for easier use. It contains two methods of stretching Both versions of the source code are attached (GUI and non-GUI). Isnt the fastest implementation so I would advise against trying to stretch large files. There are two algorithums included for stretching, the first use Overlap add of windows to create the strech where as the other takes into account phase modifications

Computer Programming for Music Technology - Quadraphonic Delay In C and Max/Msp

The final piece of a course in C and its uses in building Max/Msp objects was to design and code a quadraphonic (four tap) delay in C for use as a Max/Msp object. The delay takes an incoming mono signal and allows the user to set four delay times which correspond to the the four outputs.
