This is a KAOSSILATOR PRO, a loop recorder and sampler with a touch screen, and USB/MIDI connectivity. It is in working condition, but shows some signs of use. Audio from the LINE IN and the unit's internal sounds can be heard through headphones, but there is no sound from the LINE OUT (or only barely audible at maximum output), so it is being sold as junk. The touch panel and other buttons and knobs function without issue, so it can be used as a dedicated MIDI device or in combination with a DAW. Power adapter included. - Model Name: KAOSSILATOR PRO - Color: Black - Connectivity: USB, MIDI, LINE IN, LINE OUT - Features: Loop Recorder, Sampler - Display: Touch Screen Thank you for looking.
