LLEAPP Video

There's a video up of a performance I did with Cavan Fyans, Adam Parkinson, Shiori Usui at the Bongo Club in Edinburgh.

We had 2 days to put together an improvised, electronic performance with new people. Our practise focussed around trying to have "musical" interactions while using the laptops.

Truth Table Video up

I've finally gotten around to uploading my Truth Table video to Vimeo:

Kinetica Photos

I'm going to use this post to collect photos and media from Kinetica 2010. To start with, here's Parag's Flickr set: http://www.flickr.com/photos/pkmital/sets/72157623393186086/

Chaodependant and Memory are going to London

Thanks to the kindness of TINT, we're exhibiting both Chaodependant (by me, Owen Green and Agelos Papdakis) and Memory (by Parag Mital and Agelos Papadakis) at the Kinetica art fair in London.

Chaodependant Reconstruction

The last times Chaodependant go shown, it worked great, but the carpet base it was on looked awful. So, for taking it down to Kinetica we decided to put it on a more professional platform. Apart from aesthetics, we also wanted to address the problem that the pendulum gets further away from the pods towards the end of it's swing, and hence they have less effect on the movement.

Java libraries for ESRI ASCII Raster files

I've repeatedly come across the need to read or write Raster files in Java. These are data files which represent a rectangular grid of data using ASCII representations of numbers. An example, from GeoTools:

ncols 157

nrows 171

xllcorner -156.08749650000

yllcorner 18.870890200000

cellsize 0.00833300

nodata_value -9999

0 0 1 1 1 2 3 3 5 6 8 9 12 14 18 21 25 30 35 41 47 53

59 66 73 79 86 92 97 102 106 109 112 113 113 113 111 109 106

All values can be doubles or ints.

Max Midi Input

I've been having a fight with Max4Live recently about using midi devices. I'd like to make a gigantic patch which integrates all my control surfaces, and replaces lots of the automap functionality with something that fits my playing style better. The problem is:

  • m4l replaces max's midi functionality with its own driver, which takes midi from the Live channel the device is on.
  • so you can't use multiple devices in a patch. At least, you can't differentiate them.
  • a workaround would be to put each device on a different midi channel, and then separate the midi data inside the patch.

Servomotor Music

Servo with Phone coil attached to ArduinoServo with Phone coil attached to Arduino I started playing with an Arduino and a servo motor as preparation for a project I'm working on. Using an Arduino Nano on a breakout board, the setup just consists of plugging the three pin lead from the servo into one of the digital out ports.

Crowdsourcing GeoData

Crowdsourcing refers to using the general population to carry out tasks, often for free. Often, the idea is that by combining many inputs of unknown or variable quality, high quality outputs can be created - either through selection or some form of organisation.

More Max4Live

I've got my RhythmSequence working nicely as an M4L Device - the timing's correct, and it seems quite happy. I'll post code tomorrow when I'm awake. In the meantime, here's a picture.RhythmSequence 2RhythmSequence 2
