ChaosLooper is a DIY noise synthesizer based on the popular digital loop chip PT2399. The circuit produces diverse looping noise by amplifying the charges of the on-chip memory. The speed of the loop can be varied from slow noise floor to fast beats. A built in filter and noise switch modify the sounds. The line in can be used to seed the chaos.
