Incredible synth, future sounds!. first generation (the best one)... Works perfectly; shows some signs of use (see photos)-these don’t affect its functionality at all. I uploaded the 4 system test results for peace of mind. Owned from new. Never left the home studio, with very light use. Battery is amazing. Box, USB cable, and accessories included. Latest OS installed. Returns not accepted, unless item is faulty, which is clearly not the case here. Thanks!
