Man Hacks His Arm Prosthesis Enabling Him To Control Music Synthesizer With His Thoughts

Man Hacks His Arm Prosthesis Enabling Him To Control Music Synthesizer With His Thoughts

Bertrolt Meyer is a DJ, music producer and engineer who was born without a lower left arm.

Having worn a prosthetic arm since he was 3 months old, he upgraded to an I-Limb which is a myoelectric prosthesis that uses electrical signals from the muscles of the residual limb to control the movement of his prosthetic hand.

As an inventive musician with a passion for electronic music, Meyer had the idea to exchange his prosthetic hand with a DIY controller for his modular synthesizer. The end result is he can now alter the parameters of his music just by thinking about it.

He is calling the design “SynLimb” which is still a work in progress by the small team including Chrisi from KOMA Elektronik and his husband Daniel. He admits that even he still needs more practice at it, but his invention is nothing short of genius.

Meyer explains:

“The SynLimb converts the electrode signals that my prosthesis picks up from my residual limb into control voltages (CV) for controlling my modular synthesizer. The SynLimb thus allows me to plug my prosthesis directly into my synthesizer so that I can control its parameters with the signals from my body that normally control the hand. For me, this feels like controlling the synth with my thoughts.”

In the video below Meyer gives some background on himself and how the SynLimb works, and we can see the process in action. A future where electronic music production meets transhumanism looks exciting and full of potential.
