The MIDI CAPTAIN STD is a MIDI controller with 10 buttons and multiple connection terminals. I've used it for a few days, but it's in excellent condition with almost no scratches. All accessories are included. Please refrain from purchasing if you are overly concerned about minor details. It will be shipped in its factory default state. - Model Name: MIDI CAPTAIN STD - Connection Terminals: USB, MIDI IN, MIDI OUT, DC 9V - Expression Pedal Terminals: EXP1, EXP2 - Number of Buttons: 10 - Brand: PAINTAUDIO
