cracklebox

I’ve just bought a CrackleBox from STEIM. It’s an inexpensive, nicely made circuit bent instrument, played by touching the silvery contact pads on the box surface. The pads connect to various points on a circuit board inside the box – touching the contacts short circuits various parts of the board, resulting in semi-predictable sounds being generated.

This is a first improvisation using the CrackleBox with my time stretching instrument. The sounds are electronic and tend to be intense, so this is quite a different piece from my work with flugel horn.

A bit of history…

The CrackleBox was created by Michel Waisvisz at STEIM in the 1970s, and is one of the earliest examples of a circuit-bent instrument.

The idea in circuit bending is to take an existing piece of (battery powered) consumer electronics, expose the circuit board, and touch various points on it until you get some kind of unintended sound. You gradually create a map of the most interesting points to touch, and then solder wires between those points and some kind of contact pads that you can touch with your fingers.

There’s a great article on circuit bending here, with a more pithy definition : “the creative short-circuiting of everyday electronic sound devices to make strange new instruments and art objects”

Here’s a link to the site of an interesting custom maker of electronic instruments – BugBrand.

An early pioneer of circuit bending is Reed Ghazala, whose excellent (and beautiful) site is well worth visiting. Not only does Reed make custom instruments, but he has a wealth of material on how to circuit bend your own instruments. If circuit bending interests you, his site is a good place to start. He also has a book available on Amazon: Circuitbending: Build Your Own Alien Instruments (ExtremeTech)

Also check out Handmade Electronic Music by Nicholas Collins, which is about all kinds of hardware hacking, not just circuit bending.  It’s a great book for beginners as you start off by creating very simple sound makers with basic tools like loudspeakers and batteries.There’s chapters on making contact mics, tape head instruments, circuit bending of various kinds, and building simple synthesiszer circuits. And along the way you learn how to solder, and avoid electrocuting yourself. You really don’t need to know anything about electronics to start making noise makers with this book.

Flutes and Sensor Controlled Looping Software

Fast Tube by Casper

Something a little different …

The software that I use for the Special Needs project that I run for Eyemusic/Colourscape was originally created for Simon Desorgher, the flautist who is one of the people who run eyemusic (the other is Lawrence Casserley). Simon had for years wanted some kind of a system that would record his live playing, and the allow him to replay and manipulate those recordings in real time, while he continued to play his flute.

Not long after I performed for the first time in Colourscape, we were talking about how such a system might work, and I suggested to Simon that I could build him the software to do this in max/msp. And so LiveSampler was born. The system was somewhat cranky to use at first, but after every series of Special Needs workshops I rebuilt the software almost from the ground up, gradually improving both the functioning (eliminating things which weren’t useful, and modifying the user interface) and the reliability of the programme. Working with different disablilties gradually narrowed down the choice of sensors, until the current system uses only infra-red distance sensors, presure pads (on the floor) and acceleration/tilt sensors, which Simon has on his arms.

I also finally decided that Simon should use a dedicated computer (a Mac Mini) for his performance system, as we were having constant problems using his all purpose PowerBook. Although there have been a few performances with this system over the last two or three years, I think I’m safe in saying that this is the first completely problem free performance that Simon has had. Hopefully we now have a stable system!

Steve Lawson and I finally managed to get together today. After some initial problems with Steve’s looper, we got started, and produced this 45 minute improvisation. I’m very happy with the way it worked out – apart from a few small cuts to tidy things up, this is exactly what we [...]
