Alesis pads which look to be a great condition, like they've hardly been used. They are an unwanted gift. I tried them on my Macbook, see video, and the pads and buttons appear to all work fine. My Windows PC threw a driver error when connected via USB for some reason. Might just be my machine but I will be selling them as is so please factor that in to your purchase decision. There's also MIDI connections, though untested. They were sold as working so probably fine. Unit and original box, no cables. Uses printer style usb cable. Manual available online.
