Okay. This is a MIDI interface of some type. I cannot remember if I had it in my older MAC computer days or not. Seems I had a different one. This one might be a PC model I got somewhere along the way. Again, not sure. See photos and decide.

 Anyways, it is what it is. You get what is pictured. I have not way to test it. Sold as seen AS IS.

That said see the photos and let me know if you have any questions. Thanks. Frazier
