From Sebastian Tomczak’s site:

I wanted to be able to control a servo motor from Live directly via a USB connection using MIDI data and no software layers. This was done via a Teensy board.

Often to integrate physical electronic devices into Ableton one has to run it through an additional piece of software (usually MAX/MSP) which can muck things up and add the possibility for error. This device solves that problem.

I can’t wait to see/hear what kind of music Sebastian makes in the meatspace with his new servo capabilities.

For documentation and the code he used, check out Sebastian’s site.
