This is a Yamaha YAMAHA QY700 sequencer. It is a used item, so there are scratches and other signs of wear. The LCD screen display is good. Includes a dedicated adapter: PA-5B. A dedicated carrying bag is also included as a service. Confirmed the operation of the front panel switches (there seems to be a slightly slow-responding numeric keypad, but it works if pressed a little harder. Not very noticeable). Confirmed the operation of the jog dial. Confirmed song playback via headphones by connecting an external MIDI sequencer to the MIDI terminals (A and B). Confirmed that a 2HD floppy disk can be inserted into the floppy drive and formatted (floppy disks are not included). Functions other than the above have not been confirmed. Please understand that we cannot guarantee that all functions are operational. I do not have detailed knowledge of the equipment, so I may not be able to answer questions. Please be aware that this is an old used item, so it has some wear and tear. Although I have checked it roughly, there may be oversights in detail, so please forgive me. Please purchase only if you understand that this is an old used item. Please note that we cannot accept claims after arrival. Please note that we do not ship overseas.
