DEMO OF DYNAMIC INSTRUMENTATION:
Introduction
The purpose of this post is to propose a solution to the following future research directions offered in two papers on the Algorithmic Music Evolution Engine (AMEE) “A Flexible Music Composition Engine” and “Real-Time Emotional Adaptation in Automated Composition”, recently developed at UWO (Hoeberechts, Demopoulos, Katchabaw 2007)[10][11]. I’ve divided up the problems into two high level categories A and B: Continue reading
Last year, the development of Robot 1.1 was an experiment in electrical Engineering and the Psychology (In terms of
rhythmic human-computer interaction). It is a hardware interface which interprets ambient sound as structured pulses (using low pass filter, peak detector and tempo filter circuits) that are fed into a microcontroller which controls a solenoid powered drum stick (see previous post for video):
I have been pondering both applications and new directions for this technology. One of the main questions I kept running into while working on this project, was the question of response time. In order for a rhythmic system to be interactive, it must operate in real time. The hardware aspects of Robot 1.1 were very effective at generating a real time response. Although, the functionality was limited: Continue reading
After months of design and construction between myself & Mike Vance, we’ve designed and created a machine we never thought possible…..A robotic musician which can interact with human players. Our Intelligent Robotic Percussion system was presented at the Engineering Design Presentations at the NRC research facility this past Friday. Our system had never been operational until 9 hours before the presentation, we were a hair’s breadth away and ready to finally give up….
This Report will explore the past and current research into the areas of Beat Induction, Rhythm Recognition and percussive improvisation.First we must ask, why? In terms of current robotic systems, most focus simply on sound production (Mechanically reproducing a set of static instructions) and rarely address perceptual aspects of musicianship, such as listening, analysis, improvisation and interaction with human input. There has been some breakthrough work done on improvisation and robotic percussion in the last few years which will be explored. First we will introduce the problem of beat induction and the varying methods by which it can be achieved. We will then attempt to clearly understand how this problem will be applied to our robotic system. Furthermore we will show how we can use state-of-the-art research into similar robotic systems as a guide and stepping stone for our project.
A few years ago when I was introduced to Borges I was moved by the idea of a complete library. His short story, Library of Babel, most importantly reminded me of the difference between the infinite and the very very large. Continue reading
Last month Lyndsay’s play On The Menu was accepted into the London One Act Festival at the Grand Theater. So, out of the blue Lyndsay was responsible for casting, producing and directing a play within 3 weeks. This was a huge commitment, much more so than a normal hobby would consume….She kept up a journal of the process on her website.
Below are some photos of last weeks work:
Rehearsals were moved to our living room, where I set up a mock stage. This helped assist with staging since we had very limited time – and only a handful of rehearsals.
How Efficient Is The Financial System?
Background
In 1948 Claude Shannon wrote a paper entitled ‘The Mathematical Theory of Communication,’ later expanding this into a book by the same name. Shannon’s work was the foundation to the stunning achievements of information theory. In many respects, Shannon’s work deserves recognition as the foundation of complexity theory as well.

You may have heard that humans are not “good” at generating randomness. This video explains why a coin flip is very different from a guess….
Just finished an animation segment for Art of the Problem which helps explain the concept of probability space and how it applies to dice. Great for anyone who hasn’t thought/heard of a probability space:
I Spent some time this summer aside from school & work playing more improvisational jazz piano. I enjoy jazz because once you can place your mind in the time & space of jazz you can experience the thrill of it, even as a beginner (like me). This thrill being a dual sense of unknowing and knowing: The understanding of where you can go with musical statements, while being unsure of the actual execution or path to take. All the while being aware of some passing feeling that undulates with the music. Lately I’ve been a huge fan of Brad Mehldau – performance video.
I had a jam recorded with some friends in Waterloo last week – it was rough around the edges, but great a space to play in.
Also, I’ve acquired some old studio lights this summer and I experimented with them by making a jazz video. A guy named Luke brought over his Moog Theremin to try out as well – it’s a crazy device:
Below are the first live tests of robot 1.0 (Duncan Storey on Guitar):
Most musical robots systems focus simply on sound production (Mechanically reproducing a set of static instructions) and rarely address perceptual aspects of musicianship, such as listening, analysis, improvisation, or modification of human input. Our project aims to create a device that “listens” to a human player and responds dynamically.
We designed this (robotic drummer) system as educational and research device which makes use of interdisciplinary collaboration (Drawing from music, computer science, engineering and cognitive psychology)
Below is another video outlining some of the capabilities of this drumming robot:
I just returned from a 13 day “working vacation” in Victoria. One of the most important lessons I learned on this trip was the art of lansanga gardening. This layering process of soil eliminates the need for tilling and mixing of soil while creating a very healthy base for planting. There’s no hard and fast rules about what to use for your layers, just so long as it’s organic and doesn’t contain any protein (fat, meat, or bone). The basics of making garden lasagnas are simple:
Don’t remove the sod or do any extra work, like removing weeds or rocks.
Mark the area for your garden using a water hose or a long rope to get the desired shape.
Cover the area you’ve marked with wet newspapers, overlapping the edges (5 or more sheets per layer).
Cover the paper with one to two inches of peat moss or other organic material.
Layer several inches of organic material on top of the peat moss.
Continue to alternate layers of peat moss and organic material, until desired thickness is reached.
Water until the garden is the consistency of a damp sponge.

With every great technological or cultural revolution comes a serious paradigm shift within the ethics of our bureaucratic institutions. Electricity, Aviation, The Internet, Nanotechnology and Biotechnology are among many evolutionary plateaus which challenge existing mindsets and therefore, ethical ideals.
We currently are in the infancy of one of the greatest albeit slow moving revolutions in human history. This is undoubtedly the frontier of Space. Space exploration is a field which has recently fallen out of the hands of government agencies and into the free market. This has given birth to new (and very important) concepts such as Space Tourism, which will be the focus of this paper. Continue reading
