his will most likely be the last video of the system sounding this particular way because im changing some shit. https://youtu.be/gaFi_jUHS4s
Do the lights and music correspond to his movements or is it just choreographed?
the lights and the sound ONLY respond to movement. i dont move, there is no sound. or light, except for fluctuations of the accelerometers z-axis. no choreography, just practice 
Impressive, very nice. What are you using for a controller?
this is the controller. its a 3d printed sonocybernetic interface. there are 2 raspberry pis running pure data, mounted to my arms and the hand interface is called an exo-hand for the time being. it is 98% 3d printed, including the sensors. the only non-printed parts are the arduino, accelerometer, and wire.
is a breakdown https://www.youtube.com/watch?v=MEcG6LfpBPE
Well the Pi’s and arduino would be the controllers. The interface is the input and the output would be the speakers and lights.
hmmm…i dont use “controller” as a term in that way although i do know the context youre coming from. i thought you were using the term the way one refers to digital musical interfaces as controllers. i see and use the term controller as someone or thing that is in control. and i use the term interface to encompass the entire system which includes the computers, the microcontrollers, the sensors, lights, and procedural sound and data for feedback.
This is really impressive
