Crudbox by Steven Litt

“The CrudBox allows users to plug electronic or electromechanic devices into a 16 step, 8 channel step sequencer. While normal sequencers draw from a set bank of sounds, the CrudBox allows one to plug in devices such as turntables or solenoids or power tools, opening up the range of sounds one can sequence.”
