YAMAHA MIDI cable, 15m. The connectors are straight on one end and L-shaped on the other. It has been stored in a dark place for a long time, so I cleaned the surface and checked the operation. I tested it with note sounds and various MIDI signals, and I believe it is working without any problems. I used it a few times in live performances before, but there are no noticeable stains. Since it is a used item, please refrain from purchasing if you are sensitive to such things. Thank you.
