AMPERO CONTROL Bluetooth MIDI Controller I purchased this new about six months ago. I am selling it because I am changing my equipment. I used it at live performances, but I had switch caps on it. I disposed of the original rubber feet and attached Velcro. If you don't need the Velcro, I can remove it before shipping. All accessories are included. I am also listing this on other flea market sites, so please comment before purchasing if possible. Thank you very much.
