I bought this new about 30 years ago and used it as a minus-one karaoke machine for saxophone practice. More recently, I've mainly used it as a MIDI sound source. I'm selling it to clear out some space. It's been used quite a bit, so it shows signs of wear. The LCD screen is also quite dim. However, I've confirmed its operation and sound quality for this listing, and it can still play and receive MIDI input. Comes with an AC adapter and instruction manual. This is an old product, so please understand that it's sold as-is, with no returns. I'm open to a little price negotiation, so please contact me. @@@@@@@@@@@@@@@@@@ Yamaha QY8 Music Sequencer, a compact and versatile digital instrument. - Brand: Yamaha - Model Name: QY8 - Function: Music Sequencer - Country of Manufacture: Japan Thank you for looking.
