"This is an xoxbox built poorly by Alien Intercomm. The sequencer seems very buggy, patterns self-erasing, self-changing & sometimes patterns cannot be created, seems like a problem with the O.S.?.. but i'm no expert at either using a 303 sequencer or building 303 clones. The Headphones output is messed up, it has a lot of crackling, random & sudden volume changes & frequency changes so it will most likely need to be replaced. The Main output sounds good. All knobs and buttons function properly but the buttons are recessed lower than they should be. All parts of the synth engine function as they should. I have not tested the MIDI/DIN sync/gate/cv ports. Includes the original power supply. This is a great repair project for anyone with the ability & knowledge to do so or to use for parts for other x0xb0x's."
