New Interfaces For Musical Expression – NIME
Udder-Utter is an instrument that utters syllabic sounds derived from the Devanāgarī alphabet, which is used to write Hindi and other Indo-Arayan languages. It’s playability is inspired by the gestures involved in milking a cow. The sounds that this instrument utters are intended to be a mix of discrete and continuous in nature and are rhythmic due to their syllabic/phonetic origins. I see the Udder as an instrument for constructing and rupturing meaning through its playability by using syllabic sounds to construct monosyllabic meanings and imagery to extract formal elements.
Playing the instrument primarily involves manipulating and generating phonetic sounds. In addition the instrument allows its player to control a visual system explained below.
Screenshots of the visual system
The screen component for the performance reacted to the instrument. For this I had to interface MAX/MSP to C++ via openFrameworks and OSC.
The visual idea was to extract colours out of images and simultaneously erase them in the process. Image pixels were used to read colours and then the colours were mapped onto a stroke that was modulated depending on sensor values from the instrument. The speed with which the image lost colours depended on how the instrument was played (fast/slow gestures) and on certain other parameters.

Notes on the Imagery: I was interested in playing with the expression “milking the cash cow” by literally having the instrument sap colours out of currencies (notes/bills). I selected a series of currencies from nations that celebrate their abundance of natural resources and manpower through use of illustrations. These illustrations are references to their “cash cow”. One sees patterns of representation through iconography- such as farmers, tractors, cash crops, chimneys, industrial sheds, mineral deposits, mines etc, all of which serve as mastheads of development for emerging economies. In the globalized landscape such countries see themselves as offshore providers of resources to larger and richer countries. In turn such emerging economies are in ways the cash cow for richer nations who often sift for foreign resources before they start to consume their own as an act of self-preservation or find it cheaper to do so in their neo-imperialistic spirit. It is this vicious underrepresented portrait of national interests vs vested interests that I wanted to express through this instrument and performance. To me it was important to represent the consumed and less the consumer.

Two oscillators – SinOsc and TriOsc (triangle) at 200 and 300Hz
A sin and triangle oscillator with 200hz and 400hz base freq are multiplied in the following intervals 1,2,3,5,8,12 at 0.25 second intervals
A sin and triangle oscillator at these 1,2,3,5,8,12 intervals multiplied by their fundamental frequencies in sucession
Three triangle oscillators with 290hz and 300hz and 45hz base freq are multiplied by the following intervals 1,2,3,5,8 in 60ms intervals
64 sin waves at intervals 1,2,3,5,8,13,21,34 multipled by 21
60 sin waves at random freq between 200 and 240hz

Careful Listening · posted by vaibhav bhawsar 252 days ago
Sounds as durations, textures, intensities in my work environment.
Durations
Made the sounds coherent to the listening mind. Too short and the mind would have to fill the gaps. Whereas long continuous sounds, such as hum emanating from a air vent, would eventually recede, the mind would stop paying attention.
Textures
Textures arouse curiosity. Much like a game where you would go chasing after a sound, trying to catch up and experience its richness. In my environment it was hard to find rich textures like flowing water, footsteps on grainy soil- lack of a better word the sounds that emerge from phenomena in nature. There were as an abundance of high pitched repetitive sounds from phones, beepers, sirens etc. Most of these emanating from electronic devices or machines. The sounds someone turning pages of a book were delightful.
Intensities
Repetition, duration greatly affect the perceived intensity of a sound. As I moved away from my immediate (louder) sounds, I could only hear rumbling sounds of moving traffic a block away from my workplace.

Tools for Frameworks for Interactive Sound
Chuck
I just gave chuck a shot and I think I will enjoy using it as a tool for programming sound. It’s chucking => (similar to patching) metaphor makes good sense to me. Though I am still trying to figure out how I can do concurrent programming so that I can alter params on the fly.
OpenFramworks and STK
My other option would be to use the Synthesis Toolkit with openframeworks . I still have to really play with STK to see if I want to further work with it. The reason I want to explore this route is so that I have the opportunity to tie in some visual component (through OpenFrameworks) to the work I will be doing.
