25th Nov 2012, Music Hackspace Ensemble + Webcam instrument workshop

Update (17 Dec 2012) – Code and slides from the Webcam workshop are available on Github. –Tim

Join us on Sunday 25th of November 2012 for a day of workshopping and the first Music Hackspace Ensemble meeting with Tim Murray-Browne, our resident composer under Sound and Music’s embedded composer residency programme.

We will start with a workshop where we create instruments that respond to movement using the webcam on your laptop and software synthesisers. Afterwards we’ll have the first Music Hackspace Ensemble meeting (http://musichackspace.org/meet-tim-murray-browne-composer-in-residency/ ). Bring along your own ideas, projects and instruments, as this will be a good opportunity for all to brainstorm and discuss the possibilities and objectives of the Ensemble project. Feel free to attend either the workshop or the meeting, but it will be much better if you can make both!

25th Nov 2012 at Troyganic, 132 Kingsland Road, E2 8DY London.

12 pm to 4 pm – Workshop

In this workshop you will learn how to turn the webcam on your laptop into an instrument controlled by movement. We will be exploring the relationship between physical movement and sound, how to extract musically useful data from a video stream and how to link these together in a way that makes sense to you and any potential spectators.

The workshop will involve using

– openFrameworks to grab the webcam stream and turn it into MIDI data,

– OpenCV to track movement, create trigger zones and possibly some face-tracking,

– Ableton Live to host and control software synthesisers from the MIDI.

It will be helpful to have some experience of openFrameworks, C++ or Ableton Live but we will provide you with a starter kit that will work out the box so if you don’t have experience you’ll still have a basic working instrument to start exploring with.

What do you need to bring:

You need to bring your own laptop with Ableton installed (there is a free 30 day trial version available). If your laptop does not have a webcam you will need an external one. Also, you will need an IDE. If you are on a Mac this is Xcode which is available for free on the app store (it takes time to download so it’s best to do this before the workshop). On a PC, we will be working with Visual Studio 2010 Express, which is also available to download for free from the Microsoft website. You will also need a pair of headphones.

We will be providing a kit with OpenFrameworks and OpenCV on the day.

For the workshop please register via workshops@musichackspace.org

4 pm – Break

4.30 pm – Music Hackspace Ensemble project meeting group

After the workshop we will have a break and then return to the first Hackspace Ensemble meeting. Feel free to bring your own instruments, projects and ideas – or the instrument you created in the workshop – and we will spend some time exploring where we want the project to go and what kind of projects or events we hope to come out of it. All welcome!
