Whereas every existing sequencer and drum machine before the CrudBox created sound electronically, using either 1) analog synthesis, in which sound is created by manipulating voltage in real time, or 2) prerecorded or preprogrammed digital sound, the CrudBox creates sound by recording, looping, and editing the actions of motors, solenoids, and virtually any other physical, mechanical object and then amplifying their sounds in real time. There is absolutely no recording of audio in the CrudBox. All the sounds are created acoustically in real time.
