Lötklaus Pro: Loop-Based Control Signal Sequencer
(2008)
LKpro is a loop-based system to record, edit and play control signals. These signals can either be used to trigger cheap noisemaking children toys (aka crap) or to interrupt an audio line. LKpro was primarily developed for stage purposes, but it is also intended for use as an educational tool for “hands on toy tinkering” workshops targeting musicians. The project sees itself as part of the Do It Yourself Cultural Movement. The system is open, the firmware source code is available and re-writable using the Arduino IDE (http://arduino.cc).
