YAMAHA QY700 Music Sequencer [Included Items] Main unit, power cable, floppy disk Instruction manual, dedicated bag, dedicated cloth Power is on. I don't know how to use it, so I tried pressing a few buttons, and it responded. I haven't pressed all the buttons, so I don't know the detailed usage. Please understand that I've only confirmed by pressing a few buttons. It's a very old item. No scratches or stains on the main unit. The screen film on the main unit is also attached, but it's slightly peeling. It seems it was hardly used. The instruction manual has some stains and wrinkles, but there's no problem with reading it. It was stored in the dedicated bag, so the main unit is not dusty and I think it's in good condition. It will be carefully packed with cushioning material, with rain protection, and shipped anonymously. Thank you.
