I found this while cleaning out the storage. I'm selling it because I don't use it. [Product] YAMAHA QY70 Music Sequencer [Condition] The adapter is missing, and I tried putting in batteries, but it wouldn't turn on. Therefore, I haven't checked the internal components or performed any professional checks. Since the operation is unconfirmed, it is considered junk. I don't have specialized knowledge, so I may not be able to answer questions. *Please check the images for scratches and stains.
