Thanks everybody for the feedbacks, hopefully soon I'll be posting another piece using two arms and no stand.
@Max: Sure, so... I actually don't trigger any sound nor pre-recorded sound. All the sonic material you hear is the only muscle sound processed in real time. By "muscle sounds" I mean the voluntary contractions of arm muscles. It's a phenomenon known as MMG mechanical myography, namely the vibration of muscle fibres, which is being currently explored in biomedical computing. I use the MMG signal both as a sonic source and parameter controls. So far I could extract 6 independent binary triggers (fingers) and 2 moving events (overall continuous average and max value). There's still a lot of work to do (I'm looking into neural networks to improve the feature extraction), but it's real fun and intuitive to play with it. I've got a paper in the pipeline which will describe the development.
