Thank you for viewing. This is a "USB-MIDI Cable," a MIDI interface compatible with Mac/Win, offered at the price of two MIDI cables. I purchased it to connect to a mini keyboard for entering notes when creating sheet music, but I rarely used it, so I am selling it. I don't have the equipment to fully test its functionality, but it is displayed correctly in the Windows 11 Device Manager. It is a used item, but if you are interested, please consider it.
